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: 220.127.116.11 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,
