RAK3172 Module AT Command Manual
Introduction
RAK3172 WisDuo module is based on STM32WLE5CC chip and it is designed to simplify LoRaWAN and LoRa
point-to-point (P2P) communication. To integrate LoRa technology into your projects, the RAK3172 is implemented
with an easy-to-use UART communication interface where you can send AT commands. Through these AT
commands, you can set the parameters needed for LoRa P2P and LoRaWAN communication. You can also use
any microcontroller with a UART interface to control the RAK3172 module.
The UART serial communication is exposed on the UART2 (also identified as LPUART1 port), through Pin 2
(TX2) and Pin 1 (RX2). The default parameters of the UART2 communication are 115200 / 8-N-1. The 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 Module Datasheet.

AT Commands List
There are two AT Commands set for RAK3172 depending on the firmware uploaded on the device.
1. RUI3 AT Commands
 NOTE:
In addition, aside on UART2, AT commands can also be interfaced via UART1 Pin 4 (TX1) and Pin 5
(RX1). You can configure the settings of UART1 and UART2 interfaces via RUI3 Serial Operating Modes.
2. 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.
