Bluetooth failure for nrf51822

[Spok]

Hello,

I have been experimenting with a couple nrf51822 modules lately, and I am a at a point where one of the modules doesn't advertise in bluetooth anymore (it was working this very morning). I belive it is a hardware issue since if I flash the same code on another nrf51822, I can see it advertised (as a bluetooth keyboard).

Is there any troubleshooting steps I can do to confirm this ? I would like to know if it can be saved or if I have to swap it with another one.

Thanks

Thanks for your comments.

Couple more details: my code seems to run fine according to the debug data that I have. I am reading a UART pin and making a LED blink to get the data and I can see no particular error.

The board is a core nrf51822.

I will see if it could be an issue with the softdevice, but my loading script is supposed to reflash it every time, so it should be there.
