nReload Pin (Button) function：
1. When this pin is set to “low” during module boot up, the module will enter wireless firmware and config upgrade mode. This mode is used for customer manufacture.
(See Appendix C to download software tools for customer batch configuration and upgrade firmware during mass production)
2. After module is powered up, short press this button ( “Low” < 3s ) to make the module go into “Smart Link “ config mode, waiting for APP to set password and other information. (See Appendix C to download SmartLink APP)
3. After module is powered up, long press this button ( “Low” > 3s ) to make the module recover to factory setting.
High-Flying strongly suggest customer fan out this pin to connector or button for
“Manufacture” and “ Smart Link” application.
nLink Pin (LED) function：
1. At wireless firmware and config upgrade mode , this LED used to indicate configure and upgrade status.
2. At “Smart Link “ config mode, this LED used to indicate APP to finish setting.
3. At normal mode, it’s Wi-Fi link status indicator
High-Flying strongly suggest customer fan out this pin to LED.

1.2.4. On-board Chip Antenna
HF-LPT200 module support internal on-board chip antenna option. When customer select internal antenna, you shall comply with following antenna design rules and module location suggestions:
For customer PCB, RED color region (8.3x18.4
mm) can’t put componet or paste GND net;
Antenna must away from metal or high components at least 10mm;
Antenna can’t be shieldedby any meal enclosure; All cover, include plastic, shall away from antenna at least 10mm;
Figure 5.
Suggested Module Placement Region
High-Flying suggest HF-LPT200 module better locate in following region at customer board, which to reduce the effect to antenna and wireless signal, and better consult High-Flying technical people when you structure your module placement and PCB layout.
1.2.5. External Antenna
HF-LPT200 module supports internal antenna and external antenna(I-PEX or SMA) option for user dedicated application.
If user select external antenna, HF-LPT200 modules must be connected to the 2.4G antenna according to IEEE 802.11b/g/n standards.

2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-LPT200 module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-LPT200. One is for STA, and another is for AP. When HF-LPT200 works as AP, other STA equipments are able to connect to HF-LPT200 module directly. Wireless
Networking with HF-LPT200 is very flexible.
Notes :
AP : that is the wireless Access Point, the founder of a wireless network and the centre of the network nodes. The wireless router we use at home or in office may be an AP.
STA : short for Station, each terminal connects to a wireless network (such as laptops, PDA and other networking devices) can be called with a STA device.
2.1.1.
Basic Wireless Network Based On AP (Infrastructure)
Infrastructure: it’s also called basic network. It built by AP and many STAs which join in.
The characters of network of this type are that AP is the centre, and all communication between STAs is transmitted through the AP. The figure following shows such type of networking.
2.1.2.
Figure 9.
HF-LPT200 Basic Wireless Network Structure
Wireless Network Based On AP+STA
HF-LPT200 module support AP+STA network mode, means module support one AP interface and one
STA interface at the same time, as following figure,
Shanghai High-Flying Electronics Technology Co., Ltd(www.hi-flying.com)

HF-LPT200 Low Power WiFi Module User Manual
Figure 10.
HF-LPT200 AP+STA Network Structure
When module enables AP+STA function, Module’s STA interface can connect with router and connect to TCP server in the network. At the same time, module’s AP interface is also active and permit phone/PAD to connect through TCPB, then phone/PAD can control user device and and setting the module parameters,
The advantage of AP+STA mode is:
Users can easily setting and track user device through Phone/PAD and not change the orginal network setting.
Users can easily setting module’s parameters through WiFi when module works as STA mode.
2.2. Work Mode : Transparent Transmission Mode
HF-LPT200 module support serial interface transparent transmission mode. The benefit of this mode
High-Flying
As in this mode, the module's serial port always work in the transparent transmission mode, so users only need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In other words, the serial cable of users’ original serial devices is directly replaced with the module; user devices can be easy for wireless data transmission without any changes.
The transparent transmission mode can fully c ompatible with user’s original software platform and reduce the software development effort for integrate wireless data transmission.
The parameters which need to configure include:

2.3. UART Frame Scheme
2.3.1.
UART Free-Frame
HF-LPT200 support UART free-frame function. If user select open this function, module will check the intervals between any two bytes when reciving UART data. If this interval time exceeds defined value
(50ms default), HF-LPT200 will think it as the end of one frame and transfer this free-frame to WiFi port, or HF-LPT200 will receive UART data untill 1000 bytes, then transfer 1000 bytes frame to WiFi port.
HF-LPT200 ’s default interval time is 50ms. User can also set this interval to fast (10ms) through AT command. But user have to consider if user MCU can send UART data with 10ms interval ,or the
UART data may be divide as fragment.
Through AT command: AT+UARTTE=fash/normal, user can set the interval time: fast (10ms) and normal (50ms).
2.3.2.
UART Auto-Frame
High-Flying
Auto-frame trigger length : The fixed data length that module used to transmitting to the network.
Auto-frame trigger time: After the trigger time, if UART port received data can’t reach autoframe trigger length, then module will transmitting available data to the network and bypass the auto-frame trigger length condition.
Shanghai High-Flying Electronics Technology Co., Ltd(www.hi-flying.com)

HF-LPT200 Low Power WiFi Module User Manual
Detailed UART auto-frame function can refer to AT+ instruction set “UARTF/UARTFT/UARTFL” introduction.
2.4. Encryption
Encryption is a method of scrambling a message that makes it unreadable to unwanted parties, adding a degree of secure communications. There are different protocols for providing encryption, and the HF-LPT200 module supports following:
WEP
WPA-PSK/TKIP
WPA-PSK/AES
WPA2-PSK/TKIP
WPA2-PSK/AES
2.5. Parameters Configuration
HF-LPT200 module supports two methods to configuration parameters : Web Accessing and
AT+instruction set.
Web accessing means users can configure parameters through Web browser. When HF-LPT200 module connected to wireless network, parameters configuration is done on a PC connected to the same wireless network.
AT+instruction set configuration means user configure parameters through serial interface command.
Refer to “AT+instruction set” chapter for more detail.
2.6. Firmware Update
HF-LPT200 module supports two on-line upgrade methods:
Webpage Wi-Fi Upgrade
Remote Upgrade
Webpaged based Wi-Fiupgrade,please refer to 3.1.8 firmware upgrade page , user can upload firmware file from PC to HF-LPT200.
HF-LPT200 module also support upgrade from remote HTTP server, keep module connects to AP router before excuate remote HTTP upgrade. Remote upgrade have two methods: Direct Download and Upgrade

Direct Download and Upgrade
AT+UPURL command to set the remote directory and file name, such as:
AT+UPURL=http://www.hi-flying.com/!admin/down/,lpb.bin
After excuate this command, the module will directly download the “lpb.bin” file from remote directory and start upgrade Application.
Notes:
please contact with high-flying technical people before upgrade firmware, or maybe damage the module and can’t work again.
2.7. SOCKET B Function
HF-LPT200 support double socket communication, the socket B function is disabled by default.
After the module is started, send command “AT+SOCKB” to set the connection parameter, send command “AT+TCPDISB=on” to try to connect with TCP server. Send command “AT+TCPDISB=off” to close connection. Send command “AT+TCPLKB” to inqure TCP connection.
2.8. Multi-TCP Link Connection
When HF-LPT200 module configured as TCP Server, it supports Multi-TCP link connection, and maximum 5 TCP clients permitted to connect to HF-LPT200 module. User can realize multi-TCP link connection at each work mode.
Multi-TCP link connection will work as following structure:
