Bluetooth failure for nrf51822

Question

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

Hi, 
 There are no specific reasons why this should not work. You will have to try and fail a bit, for instance try to set breakpoints to look for asserts, floating pins (uarts), and if you have the correct low frequency clock option (internal or external 32kHz).

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.
