nrf52805- BLE Broadcasting stopped in few samples

[mohit kumar]

we are using nrf52805 after in few devices sometimes BLE is not visible(stopped broadcasting) to the receiver.

Here are the observation on that faulty device:-

1. Device BLE input supply available

2. 1.2V available  on DEC4

3. But not getting any oscillation on DSO XC1 AND XC2.

Hi

Have you tried debugging to see what is going on in your application? Do just some nRF52805 designs act faulty like this, or do all your PCBs not work? A common issue if just some of them are faulty is that the HF crystal you have is soldered on 90 degrees the wrong way. This would also explain why you don't see any oscillation on XC1/2.

Best regards,
