Hi
Last year I got a nRF52 devboard and I modified the ble uart peripheral example to flash a led depending on what it recieves from nRF uart app. It all worked fine(after some forum consulting) so I decided to try making my own version of the devboard (custom pcb) with some extra features. Once the PCB arrived, I got it working, except the ble part. I tried flashing softdevice and did everything as on the devboard, nothing helped. I tried removing the nRF52 mcu from the nRF devboard and soldering a fresh IC that I got from mouser. Same problem, ble now won't work on the devboard either. Then I ordered new devboards, repeated the same flashing process and they work just fine. I can't figure out whats wrong here, can somebody write steps for programming a blank ic from scratch, just in case I'm doing something wrong.
