RAK3172 Evaluation Board AT Command Manual

Introduction​

The RAK3172 Evaluation WisDuo Board is based on the STM32WLE5CCU6 chip and it is designed to simplify LoRaWAN and LoRa point-to-point (P2P) communication. To integrate LoRa technology into your projects, we implemented an easy-to-use USB interface, through which you can send AT commands. Through these AT commands, you can set the parameters needed for LoRa P2P and LoRaWAN communication.

The RAK3172 Evaluation Board consists of two modules:

  • RAK3372 WisBlock Core module The RAK3372 is a module built with the RAK3172 WisDuo Stamp module on a WisBlock Core-compatible PCB.
  • RAK5005-O Base Board The RAK5005-O is a WisBlock Base Board that provides a power supply, battery connector, solar panel charging connector, one IO-Slot, and four small extension slots to use WisBlock modules with the evaluation board. You can find detailed information in the RAK5005-O Documentation.

The USB serial communication is exposed on the USB connector or the RAK5005-O base board. The default parameters of the UART2 communication are 115200 / 8-N-1. Firmware upgrade is also possible through this port. To get familiar with the pin distribution of this module and find a schematic circuit of a reference application, refer to the RAK3172-E Module Datasheet.

AT Commands List​

There are two AT Commands set for RAK3172-E depending on the firmware uploaded on the device.

  1. RUI3 AT Commands
NOTE

In addition, aside on UART2 that is connected to USB-UART converter, AT commands can also be interfaced via TX1/RX1 on the WisBlock Base board. It is not configured to accept AT command by default. To configure TX1/RX1 interfaces, refer to RUI3 Serial Operating Modes.

  1. AT Commands (DEPRECATED) - FW version 1.0.4 and below
warning
  • There are RAK3172 devices loaded with old firmware versions which are not based on RUI3 (RAKwireless Unified Interface V3). These devices have v1.0.4 and below.
  • If the host microcontroller code is based on this old firmware, we have a RAK3172 AT Command migration guide that explain in detail the few differences between the two AT commands set.
