Issue: Firmware update

Setup: firmware update from to

Server: none

I can not update firmware from to
The version of Boot loader is 3.0.2.
The update does not proceed after the ‘Start sending…’ message is displayed in the
RAK LoRaButton Upgrade Tool V1.0.

Hi @najin,

Please use STM32CubeProgrammer software to update your firmware. Use the .hex file (not the .bin file) from this https://downloads.rakwireless.com/LoRa/RAK811/Firmware/. This hex file will also update your bootloader.

After that you don’t to use RAK LoRaButton Upgrate Tool V1.0 but the latest RAK DFU Tool https://downloads.rakwireless.com/LoRa/Tools/RAK_Device_Firmware_Upgrade_tool/
