Re-install RAK 3272S factory firmware

LPWAN Modules / EVBs RAK3172

I attempted to test the custom firmware using STMCUBE IDE. It failed. I would now like to re-install the factory firmware (AT Command Set). Can anyone provide directions.

Thanks,

Tim

Hi @tgibbs99 ,

You can upload the RAK3172 FW using STM32CubeProgrammer.

Download the latest RAK3172 FW Here. You need to use the .hex file and NOT the .bin file. - https://downloads.rakwireless.com/LoRa/RAK3172/Firmware/RAK3172_Latest_Firmware.zip

You can follow the guide here on how to use STM32CubeProgrammer. This is WisTrio tracker but the process is the same. You also need to connect BOOT0 pin to 3.3V so that the UART Bootloader will be activated.- RAK5205 Quick Start Guide | RAKwireless Documentation Center
