1. Introduction to the Evaluation Kit
Welcome to the JenNet-IP EK040 Evaluation Kit. This kit allows a small wireless network of devices to be monitored and controlled in either of the following ways:
Wirelessly from a remote control unit within the network
From an external device (such as a PC, tablet or mobile phone) via an IP connection (e.g. via the Internet)
The kit components are pre-loaded with a Smart Home demonstration application, developed using the NXP JenNet-IP network protocol and associated libraries. The evaluation kit can also be used in conjunction with the JenNet-IP software to develop custom wireless control and monitoring applications for lighting or other suitable targets.
This chapter introduces you to JenNet-IP and the evaluation kit by describing the:
concept of a JenNet-IP system - see
contents of the kit - see
hardware features of the kit - see
1.1 JenNet-IP System
JenNet-IP is a proprietary NXP protocol which is based on the 6LoWPAN industry standard. A 6LoWPAN system employs a blend of wired and wireless technologies to achieve flexible communication within a wide range of applications/markets.
6LoWPAN allows communication between a wireless network and remote devices via wired IP connections. A particular feature of 6LoWPAN is that communications are packaged in IPv6 (Internet Protocol version 6) messages.
JenNet-IP is an implementation of 6LoWPAN in which NXP’s JenNet protocol is used as the wireless network protocol in the system. Thus, JenNet is used as the wireless network layer of the 6LoWPAN stack, giving rise to the JenNet-IP stack (see
).
A typical JenNet-IP system includes a number of Wireless Personal Area Networks
(WPANs) connected together using a wired Local Area Network (LAN), such as an
Ethernet bus, which is itself connected to a Wide Area Network (WAN), such as the
Internet. This is illustrated in Figure 1 below.

Figure 1: Typical JenNet-IP System
Such an arrangement allows:
Nodes in separate WPANs to communicate via the LAN
A remote device (IP Host) to access a WPAN node via the WAN and/or LAN
Each WPAN is interfaced to the LAN by means of a Border-Router device.
An example application is the provision of remote access, via the Internet, to a wireless lighting system - for example, the lighting system in a warehouse could be remotely controlled from a PC in an office (which need not be on the same site) or from a mobile phone while travelling.
In practice, a JenNet-IP system can incorporate multiple LANs (and their associated
WPANs) connected together via a WAN (such as the Internet).

2. JenNet-IP System Concepts
This chapter outlines the essential concepts that you will need in order to set up and run the supplied JenNet-IP Smart Home demonstration. As indicated in
page
, a JenNet-IP system is built using a combination of Internet and wireless network technologies. Therefore, information is provided here on:
Wireless networks (WPANs)
Internet Protocol
JenNet-IP software architecture
You should read this chapter before attempting to assemble, configure and run the
demonstration (as described in Chapter 3 and
Note: These concepts are more fully described in the
JenNet-IP WPAN Stack User Guide (JN-UG-3080) and
JenNet-IP LAN/WAN Stack User Guide (JN-UG-3086).
2.1 Wireless Network Concepts
This section briefly describes the aspects of wireless networks (WPANs) that you will need to understand in order to operate the JenNet-IP Smart Home demonstration.
2.1.1 Radio Frequency
The NXP boards used as the wireless network nodes of the demonstration system communicate in the 2400-MHz radio frequency (RF) band. This is one of the standard
RF bands used by the IEEE 802.15.4 protocol on which the wireless network is built.
The band is available for unlicensed use in most geographical areas (check your local radio communication regulations).
The 2400-MHz band spans radio frequencies 2405 to 2480 MHz and is divided into 16 channels, numbered 11 to 26 (the numbers up to 10 are used for other RF bands). In the demonstration system, the channel of operation can be:
specified by the user, or
automatically selected by the system as the result of a channel energy scan
(the best operating channel is selected as the one with least detected activity)
Note: In the JenNet-IP Smart Home demonstration, the channel number is set to 0 so that the system will automatically select the best operating channel.

2.1.2 Node Types
In addition to running an application, each node of a WPAN has a networking role. A
WPAN can contain three types of node, differentiated by their networking roles, as described below:
Node Type
Co-ordinator
Router
End Device
Description
Every WPAN must have a Co-ordinator. This node has a role in starting and forming the network, and can also have a routing role
(passes messages from one node to another). The Co-ordinator is always the first node to be started and the network then forms around it.
This node passes messages from one node to another, although this routing functionality need not be used (in which case the node acts as an End Device). Messages can also originate and/or terminate at a Router.
This node is simply a place where messages can originate and/or terminate (the node does not have a routing role). In order to conserve power, an End Device can sleep when it is not required to be active.
Table 1: Node Types in a WPAN
In the JenNet-IP Smart Home demonstration system, a USB dongle from the evaluation kit acts as the WPAN Co-ordinator. The boards from the evaluation kit act as the Routers of the network. There are no End Devices in the demonstration.
Note: The Remote Control Unit of the evaluation kit acts as a ‘sleepy broadcaster’ during normal operation of the demonstration. This is not one of the standard WPAN node types listed above. It is a device that sleeps and only wakes when it is needed to broadcast commands.

2.1.3 Network Topology
A WPAN in a JenNet-IP system normally has a Tree topology, which determines how the nodes are linked and how messages propagate through the network.
A Tree network consists of a Co-ordinator, Routers and End Devices. The Coordinator is linked to a set of Routers and End Devices - its children. A Router may then be linked to more Routers and End Devices - its children. This can continue to a number of levels and can be visualised as a tree structure with the Co-ordinator at the top, as illustrated in
Co-ordinator
Router Router
End Device End Device End Device
Figure 16: Tree Network
Thus, the Co-ordinator and Routers can have children and therefore can be parents, but End Devices cannot have children and therefore cannot be parents.
In sending a message from one node to another, the message travels from the source node up the tree to the nearest common ancestor and then down the tree to the destination node.
Note: In JenNet-IP ‘standalone mode’, described in
Chapter 4 , the WPAN is initially formed as a Tree
network with the Remote Control Unit as the network
Co-ordinator. However, this topology is not subsequently used in the operation of the network. In this mode, the Remote Control Unit broadcasts a control message and any receiving Routers will re-broadcast it
(there is no selective routing down the tree). Thus, the message is received by all nodes, with the target node able to identify itself and take the appropriate action.

Chapter 2
JenNet-IP System Concepts
Different tree topologies can be formed, even from the same set of nodes. When a network is started, the resultant topology depends on a number of factors, including the order in which the nodes were started and their relative positions. The figure below shows three different but valid tree networks, all formed using a Co-ordinator, two
Routers and three End Devices.
Figure 17: Different Tree Networks
Note that a Router can be used as a ‘leaf’ node in a Tree network, in which case its routing capability is not utilised. This is the case in the JenNet-IP Smart Home demonstration (in which there are no nodes programmed as End Devices).

2.1.4 Network Identity
An individual WPAN in a JenNet-IP system can be identified in two ways:
PAN (Personal Area Network) ID: The PAN ID is a 16-bit value which is used at a low level (it is a feature of the IEEE 802.15.4 protocol) - for example, it is used in the delivery of messages sent between nodes. A value for the PAN ID is pre-set in the Co-ordinator. Routers and End Device will subsequently learn the PAN ID when they join the network.
Note: In the JenNet-IP Smart Home demonstration, the
PAN ID is pre-set to the special value 0xFFFF, which forces the WPAN Co-ordinator to select a suitable PAN
ID (which does not clash with that of other networks).
Network Application ID (or JenNet ID): This is a 32-bit value which can be used at the application level to identify the WPAN. If used, it is defined by the application developer in order to ensure that nodes joining the WPAN are running the correct application (all node applications in the WPAN should have the same Network Application ID).
Note: In the JenNet-IP Smart Home demonstration, the
Network Application ID (JenNet ID) is pre-set to the value 0x11111111. However, its value can be changed
via the Border-Router (see Section 3.2.1
) - this is useful if multiple WPANs based on this demonstration are to operate within radio range of each other.
2.1.5 Node Addresses
The basic way of referring to a node in a network is by means of a numeric address.
In a WPAN, the IEEE or MAC address of the device is commonly used. This is a 64bit address, allocated by the IEEE, which uniquely identifies the device in the world – this address is fixed for the lifetime of the device. It is also sometimes called the
‘extended’ address.
In a JenNet-IP system, a WPAN node is identified by means of its IPv6 address. This is a 128-bit address which is formed from a 64-bit address prefix (specified by the system developer) and the 64-bit MAC address of the node. For more information on
IPv6 addresses, refer to Section 2.2
below.

Chapter 2
JenNet-IP System Concepts
2.2 IP Concepts
This section briefly describes the aspects of the Internet Protocol (IP) that you will need to understand in order to operate the JenNet-IP Smart Home demonstration. For a more complete introduction to IP, refer to the JenNet-IP LAN/WAN Stack User Guide
(JN-UG-3086).
2.2.1 IP Data Packets
The Internet Protocol is used by computers/servers on the worldwide web, and other communications networks, to transfer data between each other. The data is transported across an IP network in a packet or datagram, which is a group of data bits comprising header information and payload data. The destination device for an IP packet is represented by an IP address in the packet header.
An IP data packet may need to pass through many devices or networks to reach the final destination device. IP is a connectionless protocol, which means that no circuit set-up is required before a packet is sent out - that is, there is no pre-determined path to reach the destination device. Packets between particular source and destination devices may take different routes through the network(s) at different times, according to local conditions such as traffic loads and link failures.
IP is an unreliable service based on ‘best effort’ delivery. The network makes no guarantee about the proper arrival of packets, data corruption, out-of-order delivery, duplicate arrival, and lost or dropped/discarded packets.
2.2.2 IPv6 Addresses
The Internet has so far predominantly used the Internet Protocol version 4 (IPv4). IPv4 uses 32-bit (4-byte) addresses, giving rise to an address space containing 2
32
(or nearly 4300 million) unique IP addresses. Part of this address space is reserved for special purposes, such as private networks and multi-cast addresses, reducing the number of addresses available for public Internet use by approximately 34 million.
However, the IPv4 address space is now effectively exhausted and therefore cannot support the future expansion of the Internet.
Internet Protocol version 6 (IPv6) has, so far, been introduced to a limited extent, but is destined to supersede IPv4 as a means of avoiding IP address exhaustion. IPv6 uses 128-bit (16-byte) addresses, giving rise to an address space containing 2
128
(or approximately 3.4 x 10
38
) unique IP addresses. It is unimaginable that this address space will ever be exhausted.
IPv6 128-bit addresses are normally represented as eight groups of four hexadecimal digits, where each group is separated by a colon (:). For example:
2001:DB8F:756A:0000:0000:9B67:084C:6112
Any leading zeros in a group of four hex digits may be omitted. Continuing from the previous example:
2001:DB8F:756A:0:0:9B67:84C:6112
32 © NXP Laboratories UK 2012 JN-UG-3089 v1.2
JenNet-IP EK040 Evaluation Kit
User Guide
One or more consecutive groups of 0s can be replaced with a double-colon (::). For example:
2001:DB8F:756A::9B67:84C:6112
Substitution with a double-colon may be performed only once within an address, since multiple occurrences of the double-colon can be ambiguous. For example, writing address 2001:DB84:385A:0:0:0:3A6D as 2001:DB84::385A::3A6D could be interpreted as any one of the following:
2001:DB84:0:0:0:385A:0:3A6D
2001:DB84:0:0:385A:0:0:3A6D
2001:DB84:0:385A:0:0:0:3A6D
2.2.3 IPv6 Address Components
A 128-bit IPv6 address consists of two 64-bit parts:
Address Prefix: This comprises the 64 most significant bits of the address and identifies the network. This prefix will therefore be the same for all devices in a network. The Address Prefix is itself subdivided into two parts:
Site Prefix: This comprises the 48 most significant bits of the Address
Prefix and is allocated by an Internet Service Provider (ISP) or the
Regional Internet Registry (RIR).
Subnet ID: This comprises the 16 least significant bits of the Address
Prefix and, as the name suggests, identifies a particular subnet on the organisation’s site. It is assigned by the local IT administrator.
Host Interface ID: This comprises the 64 least significant bits of the address and identifies a particular device in the network. It is normally taken to be the
IEEE (MAC) address of the device (which is itself a universally unique identifier), with bit 57 inverted.

2.3 JenNet-IP Software Stacks
A JenNet-IP system consists of a WPAN part and a LAN/WAN part. The WPAN and
LAN/WAN domains are connected via a Border-Router device, one for each WPAN - see
on page
. The Border-Router is normally the same device as the
WPAN Co-ordinator node.
Therefore, the software in a JenNet-IP system runs in three distinct parts of the system:
Nodes of the WPAN
Border-Router between the WPAN and LAN/WAN domains
Devices in the LAN/WAN domain (IP Hosts)
These divisions are illustrated in the figure below.

Border-Router: This device has both LAN/WAN and WPAN interfaces:
WPAN Interface: This side of the Border-Router runs a JenNet-IP WPAN stack, which communicates with the equivalent stack on the WPAN nodes
- this side of the Border-Router usually acts as the WPAN Co-ordinator node
LAN/WAN Interface: This side of the Border-Router runs a JenNet-IP
LAN/WAN stack, which communicates with the equivalent stack on the
LAN/WAN device (IP Host) - this side of the Border-Router must be a
Linux-based device
The two sides of the Border-Router communicate via a serial link.
LAN/WAN Device: The user application operates over a JenNet-IP LAN/WAN stack, which is connected to the Border-Router via an IP (IPv6 or IPv4) link.

JenNet-IP System Concepts
2.4 Data Message Handling
A data message may be sent from any part of the system to any other. Since a JenNet-
IP system is IPv6-based, a message is sent in an IPv6 packet.
A WPAN operates using the IEEE 802.15.4 standard protocol at its lowest level and messages are exchanged within the network as IEEE 802.15.4 frames. Thus, within a
WPAN, IPv6 packets are embedded inside IEEE 802.15.4 frames.
The sub-sections below outline the roles of the stack in sending, receiving and passing on messages in a JenNet-IP system.
2.4.1 Sending and Receiving Messages
In sending and receiving messages, the JenNet-IP WPAN stack on a wireless node operates as follows:
Sending Data: Moving down the stack, when sending a message from the application, the message is first inserted into a UDP packet which is then embedded into an IPv6 packet by the IP layer. Since an IPv6 packet is normally too large to fit into the payload of an IEEE 802.15.4 frame, the 6LoWPAN layer compresses the IPv6 packet before it is inserted into the frame at the IEEE
802.15.4 layer. If the compressed packet is still too large, 6LoWPAN fragments the compressed packet for transportation in two or more frames.
Receiving Data: Moving up the stack, when receiving a message, the payload of the incoming IEEE 802.15.4 frame is extracted. This data is then decompressed by the 6LoWPAN layer (which also combines fragmented packets, if necessary). The resulting IPv6 packet is disassembled by the IP layer to obtain the embedded UDP packet, from which the message is extracted and passed to the application.
2.4.2 Passing Messages Through the Border-Router
Passing a message through the Border-Router from LAN/WAN to WPAN domains, or vice-versa, requires the transformation of the message, as follows:
LAN/WAN to WPAN: In the LAN/WAN domain, the message is transported as an IPv6 packet (possibly inside an Ethernet packet on the LAN). In passing the message into the WPAN domain, the Border-Router must compress the IPv6 packet and insert it into one or more IEEE 802.15.4 frames, in which the message will be transported in the WPAN domain.
WPAN to LAN/WAN: In the WPAN domain, the message is transported as a compressed IPv6 packet embedded in one or more IEEE 802.15.4 frames. In passing the message into the LAN/WAN domain, the Border-Router must extract the payload data from the frame(s), decompress it and pass on the resulting IPv6 packet.

3. Smart Home Demonstration
The chapter describes how to use the contents of the JenNet-IP EK040 Evaluation Kit to set up and run the pre-loaded JenNet-IP Smart Home demonstration. This demonstration is based on a WPAN with nodes containing lights, which may be monitored and controlled as follows:
via an IP connection from a remote device on a LAN or WAN (e.g from a PC)
wirelessly from a Remote Control Unit within the WPAN
Note: A ‘standalone’ version of the JenNet-IP Smart
Home demonstration is also available which does not provide IP connectivity, allowing only wireless control of the nodes from a Remote Control Unit within the WPAN.

3.1 Demo System Overview
In the JenNet-IP Smart Home demonstration, a set of lights/sensors form a WPAN which can be accessed either from a Remote Control Unit within the WPAN or from a
PC located on an Ethernet bus. The components of the JenNet-IP EK040 Evaluation
Kit are used in the demonstration as follows:
Carrier Boards with Lighting/Sensor Expansion Boards: The four carrier boards supplied in the kit are pre-fitted with Lighting/Sensor expansion boards
(Arduino-compatible shields) and JN514x modules. Each of these four board assemblies acts as a node of the WPAN, where the JN514x module on each node is pre-programmed as a WPAN Router. In the demonstration, the white
LEDs (on the expansion boards) are the lights to be controlled. The carrier boards, expansion boards and JN514x modules are separately described in
, respectively.
Remote Control Unit: The Remote Control Unit acts as a node of the WPAN.
In the demo described in this chapter, the unit initially behaves as a WPAN
Router until it has joined the network and then acts as a ‘sleepy broadcaster’. In the latter mode, the device sleeps and only wakes when it is needed to broadcast control commands (it does not have the role of a conventional WPAN node). If sleeping, the unit must be activated using the Wake (circle) button

USB Dongle: This demonstration uses one of the supplied USB dongles programmed as a Border-Router and WPAN Co-ordinator. The dongle connects to the Linksys router (via the USB extension cable). Together they provide the Border-Router which is the interface between the WPAN and LAN/
WAN domains - the dongle handles the WPAN side of this interface. The dongle is also the Co-ordinator node of the WPAN. The USB dongle is
Linksys Router: The Linksys router has been pre-programmed with an NXP firmware upgrade which allows the router to operate in a JenNet-IP system. It is connected to the above USB dongle (via the USB extension cable). Together they provide the Border-Router which is the interface between the WPAN and
LAN/WAN domains - the router handles the LAN/WAN side of the interface and connects to the Ethernet bus on which the controlling PC is located. The
Linksys router is described in Section 1.3.6

3.1.1 Lighting Control from a PC
In this demonstration, control and monitoring commands can be issued from a PC on an Ethernet LAN connected to the Border-Router, from where the commands will be delivered to the target nodes in a WPAN. A command can be directed to an individual node in the form of a unicast or to groups of nodes in the form of a broadcast.
Two web applications are provided on the Linksys router that allow a PC user to monitor and control the lights in the WPAN. These applications run on the router and serve web pages to a normal web browser on the PC, allowing the user to interact with the WPAN nodes through the Border-Router. The applications are:
Smart Devices interface: This application provides a high-level interface for monitoring and controlling the lights in the WPAN, through easy-to-use graphical controls (on-screen buttons and a slider control). The application can be accessed by entering the following (case-sensitive) IP address into the web browser:
http://192.168.11.1/cgi-bin/SmartDevices.cgi
JenNet-IP Browser: This application provides a low-level interface for monitoring and controlling the lights in the WPAN, allowing the user to access the MIBs on the WPAN nodes (see
for an introduction to MIBs).
The application can be accessed by entering the following (case-sensitive) IP address into the web browser:
http://192.168.11.1/cgi-bin/Browser.cgi
Note: The JenNet-IP Border-Router Configuration interface is also provided on the Linksys router. This application can be accessed by simply entering the IP address of the router into a web browser on the PC:

The Remote Control Unit normally operates as a ‘sleepy broadcaster’. Thus, the unit sleeps until it is needed. If sleeping, the unit can be activated using the Wake (circle) button below the keypad. Once woken, the unit remains active for 10 minutes following the last key press before going back to sleep. When the unit is active, pressing any key will cause the left LED to momentarily illuminate (if this does not happen, you must first activate the unit using the Wake button).
3.1.3 Node States and MIBs
In JenNet-IP, the state of a node is held in a Management Information Base (MIB) as a table of variables on the node - each MIB is a logical grouping of variables.
A control operation is implemented by writing to the relevant MIB variable
A monitoring operation is implemented by reading the relevant MIB variable
To use the Smart Home demonstration, it is not strictly necessary to know about the
MIBs, although it is possible to access them from the PC by directing a web browser
to the JenNet-IP Browser application which runs on the Linksys router (see Section
).
The MIBs used by the demonstration are detailed in the JenNet-IP Smart Home
Application Note (JN-AN-1162), which describes the application code for the demonstration.

3.2 Setting Up the Demo System
This section describes how to set up the demo system using the evaluation kit components in the roles indicated in
:
Setting up the LAN part of the system is described in
Setting up the WPAN part of the system is described in
3.2.1 Setting Up the LAN Part
In setting up the LAN part of the demo system, you will need the following components:
A PC running Windows XP or Windows 7
Linksys router and USB extension cable (from the evaluation kit)
USB dongle (from the evaluation kit)
Ethernet cable (from the evaluation kit)
To set up the LAN part of the system, follow the instructions below.
Step 1 Connect the PC to the Linksys router
a) Boot up the PC.
b) Use the supplied Ethernet cable to connect the PC to the Linksys router (but do not power on the Linksys router yet). Use a blue Ethernet socket on the router (do
not use the yellow socket labelled ‘Internet’).
Step 2 Connect the USB dongle to the Linksys router
Connect the USB dongle (which is programmed as a Border-Router and as a WPAN
Co-ordinator) to the USB socket of the Linksys router via the supplied USB extension cable (use of this cable improves the radio performance of the dongle).

Step 3 Power on the Linksys router
Connect the power supply to the Linksys router. The unit will automatically power on
(this will also start the USB dongle). The power LED will first flash and then the central
LED will flash. The unit is ready when the central LED stops flashing and remains illuminated.
Since the USB dongle will also be the Co-ordinator of the WPAN, this device will create a network, for the moment consisting of just the Co-ordinator - the rest of the
network will be formed in Section 3.2.2
Step 4 Check the Linksys router configuration from the PC (optional)
If you wish, you can now check the system configuration on the Linksys router as described below - you should not need to change the default settings. Otherwise, continue to
to set up the WPAN part of the system.
a) Launch a web browser on the PC.
b) Access the JenNet-IP Border-Router Configuration interface on the Linksys router by entering the following IP address into the browser:
http://192.168.11.1/
c) On the resulting web page, log in with username root and password snap.
d) On the next web page, select the JenNet-IP tab and then select the 6LoWPANd sub-tab.
The 6LoWPANd sub-tab is illustrated in the screenshot below.

3.2.2 Setting Up the WPAN Part
In setting up the WPAN part of the demo system, you will need the following components:
LAN part of the system (set up as described in
Remote Control Unit
Carrier boards fitted with JN514x modules and Lighting/Sensor expansion boards
Antennae and batteries for the above boards
You can use as many of the boards as you like in this demonstration - for example, you may wish to initially use only one board.
Caution: The LEDs on the Lighting/Sensor expansion board are very bright at maximum intensity. To avoid damage to your eyes, do not look into them directly for an extended period of time.
To set up the WPAN part of the system (and therefore complete the demo system), follow the instructions below:
Step 1 Start the Remote Control Unit
Remove the battery compartment slide-cover on the rear of the Remote Control Unit and insert two of the supplied AAA batteries (the required polarities are indicated inside the battery compartment). Then replace the cover.
On installing the batteries, the Remote Control Unit will automatically power up. The unit will then attempt to join the WPAN that has been created by the USB dongle (Coordinator) attached to the Linksys router. The left LED on the Remote Control Unit will flash twice per second while the unit is trying to join the network, but the unit will not
be able to join until it has been whitelisted (next two steps).
Note 1: If the Remote Control Unit has been previously used, it will remember the last network to which it belonged. To clear this information and return to the factory settings, enter the following key sequence into the unit: PRG OFF DOWN OFF [# O - O].
Note 2: While the Remote Control Unit will initially join the WPAN as a Router node, it will then discard its
Router functionality and become a ‘sleepy broadcaster’
). In order to wake the unit from sleep at any time, press the Wake (circle) button located below the keypad.

Step 2 Access the JenNet-IP Border-Router Configuration interface from the PC
If not already done (from the LAN part set-up in
Border-Router Configuration interface from the PC as follows:
a) Launch a web browser on the PC.
b) Access the JenNet-IP Border-Router Configuration interface on the Linksys router by entering the following IP address into the browser:
http://192.168.11.1/
c) On the resulting web page, log in with username root and password snap.
Step 3 Display the ‘whitelist’ of WPAN nodes in the interface on the PC
a) In the interface, select the JenNet-IP tab and then select the Whitelist sub-tab.
Normally, this sub-tab shows a list of the detected WPAN nodes, identified by their
IPv6 addresses, as illustrated in the screenshot below. Those nodes that are ticked (in the checkbox on the left-hand side) are in the whitelist and so are allowed into the network. Currently, only the Remote Control Unit should be listed and should be unticked (greylisted) - if it does not appear, refresh the list by clicking Whitelist again.
48
b) Put the Remote Control Unit into the whitelist by ticking its checkbox on the lefthand side and click the Save & Apply button. The unit should now be able to join the network.
Once the unit has joined the network, the left LED will illuminate solidly for 5 seconds before being extinguished (note that the unit does not sleep and wake while trying to join a network, and should therefore not be left in this state for a long period of time in order to conserve battery power).
After joining the network, the Remote Control Unit enters a configuration mode for about 30 seconds, during which the left LED will flash slowly. This mode provides an opportunity for configuration to be performed via the Border-Router, but is not used in this demonstration. Once out of this mode, the left LED is extinguished and the unit enters ‘sleepy broadcaster’ mode (when required, the unit can be brought out of the sleep state by pressing the Wake (circle) button).

Step 4 Install antenna onto a board and start the node
Perform the following for just one node:
a) On a carrier board fitted with a JN514x module with uFl connector, install one of the supplied push-through antennae onto the board and connect the attached fly lead to the uFL connector on the module (this installation is fully described in
).
b) Insert four of the supplied AAA batteries onto the rear of the carrier board (the required polarities are indicated on the board). Also ensure that the batteries have been selected as the power source for the board, with the jumper J4 in the BAT
position (as described in Section 1.3.2
). When battery power is supplied, the colour LED module on the expansion board illuminates in red.
On power-up, the node will attempt to join the WPAN (for which the USB dongle is the
Co-ordinator). While the node is trying to join the network, the three white LEDs on the expansion board will be fully illuminated (they are very bright and, to avoid eye
damage, you must not look directly into them for an extended period of time).
There is no timeout on the node’s attempt to find and join the WPAN, but the node will
not be able to join until it has been whitelisted (next step).
Note: If the board has previously been used, it will retain settings (e.g. PAN ID) from the previous network to which it belonged. To clear this information and return to the factory settings, perform a factory reset as follows:
Wait at least 2 seconds following power-up and then press the Reset button on the carrier board 4 times with
less than 2 seconds between two consecutive presses.
After the reset, the board will try to join a new network.
Step 5 Add node to whitelist in the JenNet-IP Border-Router Configuration interface
a) Ensure that the Whitelist tab is shown in the JenNet-IP Border-Router
Configuration interface in the web browser on the PC (see Step 3).
b) Refresh the page in the browser. The new node should now appear in the list but will be unticked (greylisted). If the node fails to show in the list, you are advised to power off the board (e.g. remove the batteries) and re-start it (from Step 4b).
c) Make a note of the node’s IPv6 address and relate it to the physical node, for identification purposes later on (you may wish to label the node with the address).
d) Put the node into the whitelist by ticking its checkbox on the left-hand side. If you have prior knowledge of the node’s IEEE/MAC address and commissioning key, you can enter these details in the box revealed by clicking the Add button.
e) Click the Save & Apply button. The node should now be able to join the network.
Once the node has joined the network, the white LEDs will flash twice to indicate this and then remain fully illuminated.
Step 6 Start the next node (if any)
If there are still nodes to be started, start the next node as described from Step 4.

3.3 Operating the Demo System
This section describes how to control the lights (white LEDs) on the nodes in the
WPAN. Two situations are described:
Controlling the lights from a PC outside of the WPAN (via IP)
(see
Controlling the lights from the Remote Control Unit within the WPAN
(see
Note 1: Groups of nodes can optionally be set up in this demonstration, allowing sets of lights to be controlled collectively. You can run the demonstration without first forming groups but will only be able to control individual lights or all the lights together. If you wish to set up
Note 2: Switching off the Border-Router (Linksys router and USB dongle) will cause the WPAN to automatically enter ‘standalone’ mode, described in
Subsequently switching the Border-Router back on will cause the WPAN to return to full demonstration mode.
3.3.1 Lighting Control from PC
The lights in the WPAN can be controlled from the PC via IP. This method of control allows the lights to be switched on, switched off or dimmed individually, as a group or globally (all lights). The JenNet-IP Smart Home system must first be set up as described in
.
You can control the lights in the WPAN from the Smart Devices interface which is accessed by directing the web browser on the PC to the following (case-sensitive) IP address:
http://192.168.11.1/cgi-bin/SmartDevices.cgi
On the resulting Smart Devices page, the lights can be controlled individually from the
Individual Control tab, in a group from the Group Control tab or collectively from the
Global Control tab, as described below.
Individual Control
The Individual Control tab contains sections for all the nodes in the WPAN which have lights that can be controlled (a node is identified by its IPv6 address next to its name). For each node, there is a set of controls as depicted in the figure below.
50 © NXP Laboratories UK 2012 JN-UG-3089 v1.2
JenNet-IP EK040 Evaluation Kit
User Guide
Using the controls for an individual node, you can:
Switch the light on by clicking on the On box
Switch the light off by clicking on the Off box
Vary the brightness of the light (dimmer operation) using the vertical slider in the green bar (to the right to brighten, to the left to dim) - this is achieved by clicking the desired location in the bar (rather than moving the vertical slider)
Group Control
The Group Control tab contains a section for each group of lights in the WPAN
(groups “Hall” and “Lounge”). For each group, there is a similar set of controls as described above for the Individual Control tab. The use of groups is optional - if used, they must have been set up as described in
.
Global Control
In the Global Control tab, there is a similar set of controls as described above for the
Individual Control tab, but just one set of controls which control all the network nodes simultaneously.
3.3.2 Lighting Control from the Remote Control Unit
The lights on the nodes of the WPAN can be controlled from within the network using the Remote Control Unit. This method of control allows the lights to be switched on, switched off or dimmed. The JenNet-IP Smart Home demonstration system must first
be set up as described in Section 3.2
The Remote Control Unit allows the control of a group of nodes or all the nodes in the network. Nodes can only be controlled individually if they have been assigned to separate groups, one node per group. Therefore, if groups of nodes have not been configured, the Remote Control Unit can only be used to control all lights
(synchronously). Assigning nodes to groups using the Remote Control Unit is described in
.
The main operations that can be performed on the lights from the Remote Control Unit are described below.

Note 1: All possible operations and their associated key sequences are summarised in
Note 2: If the Remote Control Unit is sleeping (the left
LED does not illuminate when a key is pressed), the unit must be activated using the Wake (circle) button below the keypad before entering any command sequences.
For further information, refer to Section 3.1.1
Note 3: Before performing any of the operations below, you should press the key corresponding to the relevant group of nodes (A, B, C, D or *). Once a group has been selected, all subsequent operations will be applied to that group until another group is selected.
Switching on lights
The lights (in the selected group) can be switched on by pressing the key:
ON [I]
If a light is off when this key is pressed, it will be illuminated to the brightness that it had before it was last switched off.
If a light is on when this key is pressed, the command will have no effect.
Switching off lights
The lights (in the selected group) can be switched off by pressing the key:
OFF [O]
Increasing brightness of lights
The lights (in the selected group) can be increased in brightness by pressing the key:
UP [+]
The brightness will only increase while the key is being pressed, until the maximum brightness is reached (to avoid eye damage, do not look directly into
the LEDs when they are at or near maximum brightness).
If a light is off when this key is pressed, the command will switch on the light.
Decreasing brightness of lights
The lights (in the selected group) can be decreased in brightness by pressing the key:
DOWN [-]
The brightness will only decrease while the key is being pressed, until the minimum brightness is reached (the lights cannot be completely switched off with this key).
If a light is off when this key is pressed, the command will have no effect.

3.4 Configuring Groups of Lights
The lights on the nodes in the WPAN can be enrolled into groups. The lights within a group can be controlled synchronously by issuing a single command for the group. For example, in a real situation, the tablelamps in a lounge could belong to a group, allowing all the tablelamps to be switched on/off or dimmed at the same time. Note that a light can be enrolled into more than one group (or into no groups).
A group has an associated multicast address which is stored inside each member node. A command for a group includes the relevant multicast address but is broadcast to all nodes in the WPAN. A receiving node is able to use the multicast address to identify itself as a member of the group and therefore execute the command.
Groups can be configured on both the remote PC and on the Remote Control Unit.
Group configuration is described separately for the two cases in the sub-sections below.
Caution: Groups set up on the PC are not the same as groups set up on the Remote Control Unit.
3.4.1 Configuring Groups on the PC
This section describes how to set up groups of lights (WPAN nodes) for control from a PC via an IP connection. Groups of lights can be set up from the JenNet-IP Browser, which runs on the Linksys router and is accessed via a normal web browser on the PC.
The JenNet-IP Smart Home demonstration provides the following groups via the
JenNet-IP Browser:
“Hall” with multicast address FF15::A00A - this group is initially empty
“Lounge” with multicast address FF15::B00B - this group is initially empty
“All” with multicast address FF15::F00F - running nodes are automatically added to this group
The demonstration does not allow any other groups to be created.
The interface uses a group identifier which is derived from the group’s multicast address - for an IPv6 multicast address of the format FF15::x00x, the group identifer is of the fomat 0xFFx00x (for example, FF15::A00A is abbreviated to 0x15A00A).
The JenNet-IP browser is accessed by directing the web browser on the PC to the following (case-sensitive) IP address:

3.4.2 Configuring Groups on the Remote Control Unit
This section describes how to set up groups of lights (WPAN nodes) for control from the Remote Control Unit in the WPAN.
On the Remote Control Unit, there are keys for four default groups: A, B, C and D.
These groups are initially empty. In addition, there is a key for the All group (the * key).
The running nodes in the WPAN will be automatically put into the All group. To assign one or more nodes to another group (other than All), follow the instructions below:
Note 1: When assigning a node to a group, the radio transmitter of the Remote Control Unit operates in a low-power mode. This requires the unit to be brought near to the node to be added to a group.
Note 2: Group memberships set up using the Remote
Control Unit are particular to that unit and do not automatically apply to other Remote Control Units or to control from a PC via the Smart Devices interface.
Note 3: Grouping also provides a method of controlling individual nodes from the Remote Control Unit, by assigning one node per group.
Step 1 Remove the nodes that are not required in the group
The nodes that are not required in the group should be powered off (e.g. by removing their batteries).
Step 2 Locate the Remote Control Unit near to the node to be added
Place the Remote Control Unit close to the node to be added to the group.
Step 3 Add the node to the group
Add the nearby node to the group by entering the following key sequence into the
Remote Control Unit: PRG UP ON GRP [# + I A/B/C/D]
For group A, enter: # + I A
For group B, enter: # + I B
For group C, enter: # + I C
For group D, enter: # + I D
Step 4 Repeat for another node
If another node is to be added to the group, repeat the procedure from Step 2.
56
Note: A node can be removed from a group using the command PRG DOWN OFF GRP - for example, for group A the required key sequence is # - O A.

4. Smart Home Demonstration (Standalone)
The chapter describes how to use the contents of the JenNet-IP EK040 Evaluation Kit to set up and run the pre-loaded JenNet-IP Smart Home demonstration in ‘standalone’ mode. This demonstration is based on an isolated WPAN with nodes containing lights and sensors, which can be controlled wirelessly from a Remote Control Unit.
The standalone version of the JenNet-IP Smart Home demonstration does not provide
IP connectivity. Therefore, unlike in the version of the demo described in
, the standalone WPAN cannot be monitored and controlled from a remote PC via an
IP connection. In practice, a JenNet-IP system may be developed as a standalone system that can be extended to a full system with IP connectivity by simply adding a
Border-Router - for example, an entry-level lighting system may be sold as a standalone system consisting of lamps and a remote control until, with the potential to add IP connectivity by purchasing an optional Border-Router.
This chapter guides you through the set-up and operation of the standalone demo system, as follows:
provides an overview of the demo system, describing the roles of the evaluation kit components in the demonstration
details how to set up the demonstration network from the contents of the evaluation kit and run the pre-loaded software.
describes how to operate the demonstration.
4.1 Standalone Demo System Overview
In the standalone version of the JenNet-IP Smart Home demonstration, lights on the nodes of a WPAN can be controlled from a Remote Control Unit within the WPAN. The components of the JenNet-IP EK040 Evaluation Kit used in the demonstration are as follows:
Carrier Boards with Lighting/Sensor Expansion Boards: The four carrier boards supplied in the kit are pre-fitted with Lighting/Sensor expansion boards
(Arduino-compatible shields) and JN514x modules. Each of these four board assemblies acts as a node of the WPAN, where the JN514x module on each node is pre-programmed as a WPAN Router. In the demonstration, the white
LEDs (on the expansion boards) are the lights to be controlled. The carrier boards, expansion boards and JN514x modules are separately described in
, respectively.
Remote Control Unit: The Remote Control Unit acts as a node of the WPAN.
In the standalone version of the demo, described in this chapter, the unit can act as the Co-ordinator which creates the WPAN, but normally acts as a ‘sleepy broadcaster’. In the latter mode, the device sleeps and only wakes when it is needed to broadcast control commands (and does not have the role of a conventional WPAN node). If sleeping, the unit must be activated using the
Wake button below the keypad before any other keys are pressed (also refer to
). The Remote Control Unit is described in

During WPAN formation, the Remote Control Unit is enabled as a Co-ordinator through which other nodes join the WPAN. However, once the network has been formed, the Remote Control Unit is used in its default mode as a ‘sleepy broadcaster’.
Commands from the Remote Control Unit will then be broadcast to nodes, so routing down the WPAN tree will not be adhered to.
Note: The Remote Control Unit can be put into Coordinator mode for node commissioning (through the key sequence PRG ON OFF ON GRP). It will remain in this mode for 5 minutes, but the mode can be exited at any time by pressing the Wake button (below the keypad).

4.1.1 Lighting Control from the Remote Control Unit
In this demonstration, control commands will be entered into the Remote Control Unit and wirelessly broadcast (in IEEE 802.15.4 packets) to the WPAN nodes. A command can be addressed to all nodes or to a pre-defined group of nodes.
A complete list of the operations that can be performed from the keypad is provided in

The Remote Control Unit normally operates as a ‘sleepy broadcaster’. Thus, the unit sleeps until it is needed. If sleeping, the unit can be activated using the Wake (circle) button below the keypad. Once woken, the unit remains active for 10 minutes following the last key press before going back to sleep. When the unit is active, pressing any key will cause the left LED to momentarily illuminate (if this does not happen, you must first activate the unit using the Wake button).

4.1.2 Node States and MIBs
In JenNet-IP, the state of a node is held in a Management Information Base (MIB) as a table of variables on the node - each MIB is a logical grouping of variables. A control operation is implemented by writing to the relevant MIB variable.
To use the standalone Smart Home demonstration, it is not strictly necessary to know about the MIBs, but they are detailed in the JenNet-IP Smart Home Application Note
(JN-AN-1162), which describes the application code for the demonstration.
4.2 Setting Up the Standalone Demo System
This section describes how to set up the standalone demo system using the evaluation kit components in the roles indicated in
.
In setting up the standalone system, you will need the following components:
Remote Control Unit
Carrier boards fitted with JN514x modules and Lighting/Sensor expansion boards
Antennae and batteries for the above boards
You can use as many of the boards as you like in this demonstration - for example, you may wish to initially use only one board.
Caution: The LEDs on the lighting/sensor expansion board are very bright at maximum intensity. To avoid damage to your eyes, do not look into them directly for an extended period of time.
To set up the system, follow the instructions below:
Step 1 Start the Remote Control Unit
Remove the battery compartment slide-cover on the rear of the Remote Control Unit and insert two of the supplied AAA batteries (the required polarities are indicated inside the battery compartment). Then replace the cover.
On installing the batteries, the Remote Control Unit will automatically power up.
Step 2 Put the Remote Control Unit into Standalone Mode
By default, the Remote Control Unit is configured to join an existing WPAN in the full
JenNet-IP Smart Home demonstration described in
Chapter 3 . To exit this mode and
put the unit into standalone mode, enter the following key sequence into the unit (you may first need to activate the unit using the Wake button - see
PRG DOWN UP DOWN [# - + -]
The unit will then act as a WPAN Co-ordinator and create a WPAN. The left LED on the Remote Control Unit will flash while the unit is creating the network and will stay
60 © NXP Laboratories UK 2012 JN-UG-3089 v1.2
JenNet-IP EK040 Evaluation Kit
User Guide
illuminated for a few seconds once the network is created (with no other nodes yet).
The Remote Control Unit will then revert to ‘sleepy broadcaster’ mode.
Step 3 Install antenna onto a board (if not already done) and start the node
Perform the following for just one node:
a) If not already done, on a carrier board fitted with a JN514x module with uFl connector, install one of the supplied push-through antennae onto the board and connect the attached fly lead to the uFL connector on the module (this installation is fully described in
b) Insert four of the supplied AAA batteries onto the rear of the carrier board (the required polarities are indicated on the board). Also ensure that the batteries have been selected as the power source for the board, with the jumper J4 in the BAT
position (as described in Section 1.3.2
). When battery power is supplied, the colour LED module on the expansion board illuminates in red.
On power-up, the node will search for a WPAN to join. During this time, the three white
LEDs on the expansion board will illuminate at full intensity (they are very bright and,
to avoid eye damage, you must not look directly into them for an extended period of
time).
Note that there is no timeout on the node’s attempt to find and join a WPAN.
Note: If the board has previously been used, it will retain settings (e.g. PAN ID) from the previous network to which it belonged. To clear this information and return to the factory settings, perform a factory reset as follows:
Wait at least 2 seconds following power-up and then press the Reset button on the carrier board 4 times with
less than 2 seconds between two consecutive presses.
After the reset, the board will try to join a new network.
Step 4 Allow the node to join the WPAN (of the Remote Control Unit)
To allow the node to join the WPAN of the Remote Control Unit (note that at this stage, the node will be assigned to a group):
a) Bring the Remote Control Unit to within direct radio range of the node.
b) Put the Remote Control Unit into Co-ordinator mode and enable the node to join the WPAN by entering the following key sequence into the unit:
PRG ON OFF ON GRP [# I O I A/B/C/D/*]
Note: In this key sequence, you must specify the group
GRP to which the node will be assigned: A, B, C, D or *.
The star (*) option refers to the All group. A node is automatically added to the All group (as well as to the specified group). However, you can specify the All group in the key seqeunce if you do not wish the node to be assigned to any other group.
JN-UG-3089 v1.2

Chapter 4
Smart Home Demonstration (Standalone)
Following the above key sequence, the Remote Control Unit will allow 5 minutes for nodes to join the network, during which the left LED on the unit will be illuminated. At the end of this period, the unit will revert from Co-ordinator mode to
‘sleepy broadcaster’ mode. You can escape from Co-ordinator mode at any time by pressing the Wake button (below the keypad).
c) Wait for the node to successfully join the network, which is indicated by the white
LEDs on the node flashing twice and then remaining illuminated at full brightness.
In the case of a successful join, the left LED on the Remote Control Unit will also blink. If the node fails to join, power off the node (e.g. remove the batteries) and restart from Step 3 (possibly bringing the Remote Control Unit closer to the node).
d) Once the node has joined the network, if the 5-minute timeout has not elapsed then press the Wake button (below the keypad) on the Remote Control Unit to escape from Co-ordinator mode.
Step 5 Check that the node has joined the WPAN
Use the Remote Control Unit to check that the node has joined the WPAN. For example, use the unit to switch off the lights on the node by entering the following key sequence into the unit:
GRP OFF [A/B/C/D/* O] where GRP identifies the group to which the node was assigned.
Then switch all lights in the WPAN back on by entering the command GRP ON [* I].
If the node fails to respond to commands from the Remote Control Unit, you should return to Step 4 (and failing that, to Step 3).
Step 6 Start and install the next node (if any)
If there are still nodes to be started, start and install the next node as described from
Step 3.

4.3 Operating the Standalone Demo System
This section describes how to control the lights (white LEDs) on the nodes in the standalone WPAN from the Remote Control Unit. The lights can be switched on, switched off or dimmed. The standalone JenNet-IP Smart Home demonstration
system must first be set up as described in Section 4.2
The Remote Control Unit allows the control of a group of nodes or all the nodes in the network. Nodes can only be controlled individually if they have been assigned to separate groups, one node per group. Therefore, if groups of nodes have not been configured, the Remote Control Unit can only be used to control all lights
(synchronously).
The main operations that can be performed on the lights from the Remote Control Unit are described below.
Note 1: All possible operations and their associated key sequences are summarised in
Note 2: If the Remote Control Unit is sleeping (the left
LED does not illuminate when a key is pressed), the unit must be activated using the Wake button below the keypad before entering any command sequences. For
further information, refer to Section 4.1.1
.
Note 3: Before performing any of the operations below, you should press the key corresponding to the relevant group of nodes (A, B, C, D or *). Once a group has been selected, all subsequent operations will be applied to that group until another group is selected.
Switching on lights
The lights (in the selected group) can be switched on by pressing the key:
ON [I]
If a light is off when this key is pressed, it will be illuminated to the brightness that it had before it was last switched off.
If a light is on when this key is pressed, the command will have no effect.
Switching off lights
The lights (in the selected group) can be switched off by pressing the key:
OFF [O]

B. Firmware Re-programming
The following components of the JenNet-IP EK040 Evaluation Kit are supplied preprogrammed with the JenNet-IP Smart Home demonstration but can be reprogrammed with other applications:
Remote Control Unit - see
JN514x modules - see
USB dongles - see
B.1 Re-programming Remote Control Unit
The firmware of the Remote Control Unit can be re-programmed using the supplied programming dongle (part number: DR1128) . This re-programming is conducted as follows:
1.
Remove the battery compartment cover on the rear of the unit to reveal the J3 header for the programming dongle (if there are batteries in the compartment, you can leave them or remove them).
2.
Insert the programming dongle onto the header in the battery compartment, as illustrated below.
68 © NXP Laboratories UK 2012 JN-UG-3089 v1.2
JenNet-IP EK040 Evaluation Kit
User Guide
3.
Use one of the supplied ‘USB A to Mini B’ cables to connect the programming dongle to a USB port of your PC.
4.
Use the JN51xx Flash Programmer application on your PC to load the new firmware image into the Remote Control Unit. You must use the standalone
JN51xx Flash Programmer tool (JN-SW-4007), which is available from
www.nxp.com/jennic/support/software. The programming procedure is described in the JN51xx Flash Programmer User Guide (JN-UG-3007), but ignore references to resetting the device and putting it into programming mode - for the dongle, this is done automatically.
5.
Once programming has completed, remove the programming dongle and replace the battery compartment cover.
Note: The programming dongle can also be used as a
UART port on the Remote Control Unit for debug purposes.
B.2 Re-programming JN514x Modules
The Flash memory devices on the supplied JN514x modules are pre-programmed with the software for the JenNet-IP Smart Home demonstration. At some point, you may wish to re-program the modules with another application. To do this, you must use the standalone version of the JN51xx Flash Programmer utility (JN-SW-4007), which is available from www.nxp.com/jennic/support/software. The programming procedure is described in the JN51xx Flash Programmer User Guide (JN-UG-3007).
Note that when re-programming the JN514x modules on the carrier boards in this kit, you must use one of the supplied ‘USB A to Mini B’ cables to connect a USB port of your PC to the carrier board.
JN-UG-3089 v1.2

Appendices
B.3 Re-programming USB Dongles
The necessary binary application for the JenNet-IP Smart Home demonstration has been pre-loaded in the Flash memory of both dongles. However, you can easily reprogramme a dongle with another binary file through a USB port of your PC and the
NXP LPC1343 device on the dongle. The replacement binary file must be a specially prepared file called FIRMWARE.BIN.
B.3.1 Preparing the Binary File
Before a custom application binary file can be programmed into the USB dongle, a utility called jn514x_firmware.exe must be run on the file to strip out a 4-byte header.
This utility is provided in the JenNet-IP SDK (JN-SW-4051) and is located as follows:
C:/Jennic/Tools/NXP_USBDongle/jn514x_firmware.exe
The utility can be run from a bash shell using the following command:
/cygdrive/c/Jennic/Tools/NXP_USBDongle/jn514x_firmware.exe
with the following options:
-f used to specify the name of the input file
-m used to specify the IEEE/MAC address of the target device (: separated)
-c used to specify the target chip type (in this case, should be JN5148J01)
Therefore, the required usage is:
.../jn514x_firmware.exe -f <app path/name> -m <MacAddress> -c JN5148J01
The utility will output the modified file as firmware.bin in the directory of the utility. This file must be renamed as FIRMWARE.BIN (all capitals).
B.3.2 Programming the Dongle
This re-programming of the dongle uses a simple ‘drag and drop’ method within
Windows Explorer, as follows:
1.
Plug the USB dongle into a free USB port of your PC (if an ‘Installing driver’ message is displayed, refer to
Installing Device Driver for USB Dongle below).
2.
Open Windows Explorer - the dongle should appear as ‘Jennic_USB’.
3.
If the dongle currently contains any files, delete them.
4.
Within Windows Explorer:
d) Navigate to the new FIRMWARE.BIN file on your PC.
e) ‘Drag and drop’ or ‘copy and paste’ the new binary file onto the USB dongle.
