User Manual

Product Description

RAK3172 Low-Power Long Range Transceiver module that is based on STM32WLE5CC chip. It provides an easy to use, small size, low-power solution for long range wireless data applications. This module complies with Class A, B & C of LoRaWAN 1.0.3 specifications. It can easily connect to different LoRaWAN server platforms like The Things Network (TTN), Chirpstack, Actility, etc. It also supports LoRa Point to Point (P2P) communication mode which helps you in implementing your own customized longrange LoRa network quickly.

You can configure the mode and operation of the module using AT commands via a UART interface. RAK3172 also offers low power features which is very suitable for battery powered applications.

Interfacing with RAK3172

RAK3172 module can be configured using AT commands via UART interface. You need a USB to UART TTL adapter to connect the RAK3172 to PC’s USB port and a serial terminal tool. It is highly recommended to use RAK Serial Port Tool (opens new window)so you can easily send AT commands and view the replies from the console output.

Connect to the RAK3172

Mount the RAK3172 Core module on a RAK5005-O Base board.
Connect the Base board with the computer using USB cable
Any serial communication tool can be used; but, it is recommended to use the RAK Serial Port Tool (opens new window).
Configure the serial communication tool by selecting the proper port detected by the computer and configure the link as follows:
♦ Baud Rate: 9600 baud
♦ Data Bits: 8 bits
♦ Stop Bits: 1 stop bit
♦ Parity: NONE

Configuring RAK3172

To enable the RAK3172 module as a LoRa P2P module or a LoRaWAN end-device, the module must be configured and parameters must be set by sending AT commands.

The first step is to connect the RAK3172 module to the USB-UART converter computer as described in the previous section. Using a serial communication tool, you can now send commands to the RAK3172. For example, sending the AT will display OK. For the details of all supported AT commands, refer to AT Commands for RAK3172.
