So have you used the debugger to see what's going on?

First off, can you check that the crystal oscillator(s) on the defect device are soldered on the right way, a rather common issue is that these are soldered on 90 degrees off for instance.

Have you made sure that both devices have the same application flashed onto them, and that both (when using BLE) have a SoftDevice flashed onto them as well?

Best regards,

Simon

What happens? I can't see ble advertising on my phone with the faulty one.

I agree that no real world things can be identical, that's why I want to be sure that all the things that can be identical (flash and other things that I am looking for) are identical before saying that the board is faulty.

In what way(s), exactly?

In the real world, no two things are ever truly identical - there are always (slight) variations.

Plus, there is the possibility that one may be faulty / damaged - or even incorrectly manufactured.
