Issue: Was anyone successful in upgrading the firmware of RAK7204 to the latest version (RAK7204_v18.104.22.168.H.R App.bin)?
I have tried it with the “LoraButton Upgrade Tool V1.0” and with the “RAK Device Firmware Upgrade Tool v1.4.exe”. Both of them didn’t work.
The device was in Boot Mode and the boot-jumper was removed. With both tools, I got a timeout error and it’s not possible to upgrade to version 22.214.171.124.
I can only flash firmware-version v126.96.36.199 with the LoRaButton Upgrade tool.
