Hi! Just to close this ticket.

I read the RESETREAS register as you suggested, but I also tried to search the main reason for the reset.

Finally, it seems that it is something related with this ticket

I upgraded softdevice s132_nrf52_4.0.3 to softdevice 4.0.5 and I haven't seen the error anymore.

I will continue testing with others version to stay at the most recent/compatible with my program.

Hi,

Could you read the RESETREAS register after a reset and share your code?

Hi!

I'm using SDK S132 v4.0.3. I don't use watchdog but I tried to debug using other methods.

First, writing in a non-volatile variable to save the information after reset.and second,a SDCard which writes when radio_event_handler is on or off and and second

When using the SD error happens in both situations (on and off). The variable in RAM shows the same behaviour although sometimes it gets corrupt.

I also tried with intervals, when it reached BLE_ADV_EVT_IDLE, I used ble_start_advertising to start again.

I tried both fast and slow advertising and the result is the same. The thing is that sometimes you have to wait many hours until reset happens.

Hi,

Which SDK and Softdevice version are you using?

Are you using a watchdog? Could you check the RESETREAS register for the reset reason?

Have you tried implementing advertising in intervals? Does the issue still persists?
