check current firmware version
need to update the firmware, its 18.104.22.168.H and the latest is 22.214.171.124.H
check current bootloader version
check the bootloader version with STM32CubeProgrammer as described in the getting started document, V3.1 … that’s fine, no need to update
update the firmware
Because the current firmware on this device is newer then V126.96.36.199 , we need to set the device in bootmode with an AT command.
You can do this with the RAK serial port tool
device is now in bootmode… we close this app and (download) start the RAK LoRaButton Upgrade Tool.
download and select latest firmware and press START
do a little dance
close this app and recycle power, start the port tool again to see if your update was succesfull.
it was and we’re up to date.
next step to get the device connected to TTN
