What I wonder, can I change the main.c file to log e.g. BLE errors etc.?
--> I.e. adapt this file here, compile and flash:
https://github.com/espruino/Espruino/blob/3a1b5142a281e5c2f9e827d2901abf88b13167f7/targets/nrf5x_dfu/main.c
Then I could try to log the error code etc. on the screen - if this would help.
Cheers, David
