@Jorge I got it working though I can't remember what the problem was in the end. I've sent you some of my code snippets for you to compare with. Please update here if you find your problem and I'll mark it as the answer.

@SBatt Did you discovered what was the problem? I'm having a similar problem and wanted to know your solution, if you have one.

Thanks again for your help. I was really hoping it was something stupid I missed! The ISP130301 module has an internal 20ppm crystal (P/N:NX2012SA), though I'll try using the internal Oscillator.

The only other thing I can think of is a bad matching circuit for the Antenna, I'll check that out next.

Cheers.

There are few PAN's in rev2 IC that were fixed in rev3. But if you moved from rev2 to rev3 then it should have worked for you.

Can you debug little bit and narrow down the scope of the problem. Maybe some initialization is failing!!!???

Most common thing in your type of situation is the LFCLK. by default in the SDK examples the function ble_stack_init uses external crystal clock NRF_CLOCK_LFCLKSRC_XTAL_20_PPM.

Make sure that you have it on your device else you need to change this to internal RC clock whose definitions you can find in nrf_sdm.h inside enum NRF_CLOCK_LFCLKSRCS
