Unable to flash RAK4600 using firmware upgrade tool

Hi all,

I have tried everything, but for some reason my RAK4600 does not want to be flashed using the firmware upgrade tool. I flashed the latest firmware: 3.4.0.14 using a j-link and the nrfjprog tool. I expected the firmware tool to work after that, since I read that the bootloader should be included in that file (I used the .hex file). The module responds to AT commands as expected, but I get a ERROR 1 response after sending at+set_config=device:boot. What could be wrong? Maybe I can try to flash the bootloader again? Does anyone have a link to the right bootloader?

Many thanks in advance,

Daan

Hello Daan,

The RAK4600 cannot be flashed with the DFU tool. You can flash the firmware only over SWD (Jlink) interface or over BLE.
The command at+set_config=device:boot is not supported by the RAK4600 firmware.

Hello Bernd,

Thank you for the quick response. That’s good to know! I’ll try flashing over SWD than.
