Possible reasons for BLE suddenly not working?

pctj101

I have a custom board that is running the NRF52832 from the Redbear MB-N2 Module.

Suddenly the board will not BLE advertise. I loaded the HRM example and that won't advertise either.

Then I loaded the same files on another 2 boards (1 custom, 1 redbear blend2) and the same binary successfully advertises on BLE.

Is there a chance I "burnt out" the BLE transmission ability of the NRF52? Anything I should check?

    Hi Petter, Thanks for asking some follow on questions.

    I believe the softdevice is properly in place for 2 basic reasons:

    1. I mergehex the softdevice into the hex file so it's impossible to forget
    2. The same hex file on a different board successfully does BLE advertisement

    The remainder of my application works just fine. I2C, UART, GPIO letc. So the board is at least largely alive. :)
