STEVAL-IDZ3xxV1 demonstration kit for the SPZB32W1x2.x
series of 802.15.4/ZigBee® radio communication modules
Introduction
The STEVAL-IDZ3xxV1 is a demonstration kit from the SPZB32W1x2.x series of
802.15.4/ZigBee® RF modules based on the STM32W108CB microcontroller that integrates
a 32-bit ARM® Cortex™ M3 microprocessor and a 2.4 GHz, IEEE 802.15.4 radio.
Accordingly, with the loaded protocol stack and application SW, the STM32W108CB
microcontroller is suitable for different types of wireless network scenarios.
Each STEVAL-IDZ3xxV1 kit enables the user to test the RF module performances, the
features of the protocol libraries defined for the microcontroller, and to prototype the target
802.15.4/ZigBee application. The kit includes a development board and a software library
that can be integrated into the structure of the packages available from the ST website for
the use of ZigBee PRO, Zigbee RF4CE and simplified MAC on the STM32W108CB
microcontroller. The STEVAL-IDZ3xxV HW integrates an RF module belonging to the
SPZB32W1x2.x series together with an extended number of external connectors that allow
the integration of peripherals as requested by the target application.
The STEVAL-IDZ3xxV1 kit can be used for the following purposes.
■
Demonstration: ZigBee PRO. By using the sensor/sink application example integrated in
the kit and two development boards, the user can easily set up a demo showing a few of
the basic features of the ZigBee protocol stack.
■
Development: by using external equipment consisting of a development environment for
the STM32W, the kit can be used to prototype and debug a target application.
This document describes the hardware and software components of the STEVAL-IDZ3xxV1
and provides instructions for setting up the hardware and loading and running the
application examples. This document is not meant to be a ZigBee tutorial and assumes that
the user is familiar with IAR development tools and the basic features of the STM32W108CB
microprocessor.

IAR toolset
The IAR embedded Workbench IDE for ARM is a very powerful integrated development
environment used for developing and managing complete embedded application projects.
Note:
For programming (and/or debugging) using the IAR toolset, an IAR J-Link JTAG emulator is
required. The IAR J-LINK is a JTAG emulator designed for ARM cores. It connects via a
USB port to a PC running Windows 2000 or XP. It has a built-in 20-pin JTAG connector,
which is compatible with the standard 20-pin connector defined by ARM. When using the
IAR J-Link, an external power supply is required to power the STEVAL board. The first time
the IAR J-Link is plugged into the PC's USB port, the user is requested to provide the
relative J-Link driver. To do this, browse to the IAR installation directory and select the folder
ARM > Driver > J-Link. The IAR toolset and the IAR J-Link are not provided with the kit. For
detailed information and documentation about IAR products, refer to www.iar.com. As an
alternative, ST-Link can be used in place of the IAR J-Link emulator. ST-Link is a very lowcost, in-circuit debugger/programmer for STM32. It connects to the application or
demonstration board for programming and debugging via a JTAG std connection. The
complete ST-Link documentation is available from www.st.com.

Install the CP2102 drivers
The following steps are needed to install the driver for use of the USB-UART bridge CP2102
on your PC.
Note:
The driver can be found on the silicon labs web page at www.silabs.com, and a copy is also
included in the IDZ3LIB.
Unzip the file CP210x_VCP_Win2K_XP_S2K3.zip
Double click on CP210x_VCP_Win2K_XP_S2K3.exe to install the driver
Connect the STEVAL by inserting the USB connector in one of the USB slots of the PC.
To use the USB-to-UART bridge, the jumpers JP3, JP4, JP5, and JP6 must be configured as
shown in Figure 11. When the driver is correctly installed, it is possible to see the COM
associated to the STEVAL listed in the “Ports” field of the computer management utility of
the PC (see Figure 15).
If you want to connect multiple STEVALs to the PC via the USB-to-UART bridge, it is
necessary to appropriately reprogram the ID associated to the CP2102 component. A tool
from silicon labs can be used for this operation. That tool and related documentation is also
available (an144sw.zip) in the IDZ3LIB.

Install and run the sink-sensor application
Install and run the sink-sensor application
The sink-sensor application included in the IDZ3LIB is provided to allow the STEVAL user to
easily set up a ZigBee network by using the hardware included in the kit. The sink-sensor is
derived from the homonymous application included in the EmberZnet package libraries and
shows the basic features of a distributed sensor network for remote monitoring.
The sink-sensor application requires the use of at least two different STEVALs (or other
compatible hardware), respectively running sink and sensor applications in the same
network.
3.1
Sink-sensor sample application
The sensor-sink application is an example of a complete application that implements a
distributed sensor network with one or more data collection points (called “sensors”) and
one data storage point (called “sink”). This application uses a “push” style of communication,
where the sensor periodically sends reports to the sink without needing to be asked for this
data.
In this specific case, sensors capture temperature data measured by the sensor that is
integrated in the STEVAL and sends that data to a sink that is connected to a PC. Data
collected by the sink are then available at serial ports associated to the STEVAL when it is
connected to a PC and they can be used by every kind of application running on it.
The sink node is also set up to be the ZigBee coordinator device, and it forms the network
automatically on first startup, therefore retaining these settings across reboots. The sink
sends out advertisements (SINK_ADVERTISE) at regular intervals using a multicast (after
making a many-to-one route request). If the joining procedure is activated by pushing a
button on the board, a not joined sensor hearing a SINK_ADVERTISE sends a message
(SENSOR_SELECT_SINK) requesting to use that sink (after setting its address table entry
to the sink). If the sink has a free address table entry it responds with a sink ready message
(SINK_READY) and, at that point, the sensor is free to send data (DATA) to the sink at fixed
intervals (as set by SEND_DATA_RATE).
The sink sensor communication is set with the following network parameters:
CHANNEL - 26
PANID 0x01ff
APP_EXTENDED_PANID {'s','e','n','s','o','r',0,0}.
The payload of the packet sent by the sensor is 12 bytes long and it includes:
8 bytes corresponding to the 64-bit address of the sender
2 bytes corresponding to the temperature values as captured by the sensor integrated
in the STEVAL
2 bytes corresponding to the voltage level as measured on the voltage meter integrated
in the STEVAL.
The sensor-sink application allows the user to interact with STEVAL by sending commands
through a serial port (the COM associated to STEVAL when connected to the PC). Refer to
the sink and sensor source files for the list of supported commands and implementation.

Install and run the sink-sensor application
3.2
UM1454
Load sink-sensor on the STEVAL
The kit includes the “bin” images of the sink-sensor application that can be loaded onto the
STEVAL by using the Flasher downloader tool. The following steps should be followed.
Configure the jumpers JP3, JP4, JP5 and JP6 as in Figure 11 for use of USB-UART
bridge
Configure the jumpers JP2 as in Figure 13 to activate the boot signal
Plug the STEVAL into one of the USB slots on the PC and identify the serial port
associated to the STEVAL (by using the Computer Management Utility of the PC) (See
Figure 15). The power-LED (LED1) goes on to indicate the STEVAL is powered via the
USB
Run the Flasher as described in Section 2.6.6 by using the batch file where the user
has specified the COM port to use and the sink.bin or sensor.bin (from C:\Program
Files\STMicroelectronics\EmberZNet-4.x.x\STM32W108\app\idz3lib\prebuilt\sensor)
file as per user needs
Unplug the STEVAL and configure the jumper JP2 as in Figure 14 to use the loaded
application.
Note:
The previous step can be followed to load any other “bin” images on the STEVAL.
3.3
Setting-up a network and running the sink-sensor
application
This section describes how to use the STEVAL to run the sink-sensor application. Refer to
the source code files for details on the implementation and use of the EmberZnet APIs.
The sensor-sink application can be run once the user has successfully loaded the
sensor and sink applications as described in Section 3.2 on two different STEVAL
boards
Verify that jumper JP2 is configured as represented in Figure 14
In the procedure described below, the choice made was to connect both sensor and
sink to a PC via the mini-USB connector. That allows to monitor the serial messages of
both the sensor and the sink by using the HyperTerminal utility on your PC
Connect sink. Verify JP3-4-5-6 are as in Figure 11 and connect STEVAL-sink to one of
the USB slots of the PC. LED2 and LED3 start toggling which indicates the sink has
appropriately formed the network as coordinator
Open a HyperTerminal by specifying the COM associated to STEVAL-sink (see
Figure 15) and by using the configuration 115200-8-NONE-1-NONE. The serial
messages are seen, as shown in Figure 17. Press the reset button on STEVAL to make
the sink application start from the beginning. The init, form and sink advertise
messages are shown in Figure 17.

Figure 17. Sink advertise and form network messages
Connect sensor. Verify JP3-4-5-6 are as in Figure 11 and connect STEVAL-sensor via
the mini-USB to the PC. You see LED3 ‘on’
Open a HyperTerminal by specifying the COM associated to STEVAL-sensor (see
Figure 15) and by using the configuration 115200-8-NONE-1-NONE
To allow the sensor to join the network set up by the STEVAL-sink, press the SW3
button on STEVAL-sink and the SW3 button on STEVAL-sensor in an interval shorter
than 60 seconds. If this join operation sequence runs successfully the LED2 and LED3
on the STEVAL-sensor start toggling
Figure 18 and 19 respectively show the serial messages of sink and sensor
respectively during the join phase. After the network is set up, the sensor sends a data
packet every 10 seconds that contains the temperature value, the power supply voltage
and the node ID, as also shown in the same figures.

Figure 19. Sensor: join and data messages
Commands can be sent through the HyperTerminal to both the STEVAL-sink and the
STEVAL-sensor. For example, in Figure 20 the result of the command “i=print node
info” sent to STEVAL-sink can be seen.
Figure 20. Sink: “i” command output
Note:
The application uses a constant called MISS_PACKET_TOLERANCE as a threshold for
fault tolerance. On the sensor, this threshold controls how many message timeouts can be
permitted between the sensor and sink before the sensor decides to attach itself to a
different sink.
For a sink, this controls how many data reports can be missed from a sensor before the sink
“forgets” about the sensor (stops maintaining a record of its attachment). Although bindings
are kept on the sink node to track the attached sensors, these could easily be made
temporary (used only for the SINK_READY message) to allow the sink application to
support more nodes without enlarging the binding table, assuming that the sink application
does not care which sensors and how many sensors are attached to it.

RoHS compliance
Note:
The sensor advertisement is a broadcast. The behavior of such a broadcast in the network
depends on the network topology and density. ZigBee limits the number of broadcasts that
can be active in a network to 10 to minimize the network disruption and loss of bandwidth.
As this network increases in size or density, the rate of the sensor advertisement should be
reduced in frequency.
