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?

    Thanks all for attempting to provide insight. I came back to this today to find another board was being enumerated by iOS with a "blank" name. So even though the device was detected, the name was blank, so I didn't realize the device was enumerated.

    Subsequent reflash of the same program seems to have cleared this up, but I suspect there's some iOS cache issue involved here more so than a strange soft-device interaction.
