Hi ole, I am debugging my application. I did same as above mentioned comment. But couldn't get the line number and filename. Please advice me on how to see values of line no. and filename in debugger.

If you see unexpected resets, uncomment ble_debug_assert_handler in app_error_handler, remove the reset, run the project with a debugger, and stop it if you see the ASSERT LED light up. This will show you what failed.

If you don't understand the problem you're seeing, post a new question with all information you have.

Thank you! It works well now! But another problem happened. Once I disconnect it from dongle, the system will be reset soon. What happened?

Take a look at this: https://devzone.nordicsemi.com/index.php/advertising-with-no-timeout

I met the same problem. And I changed 180s to 0, but it doesn't work at all. I also found it must small than 180s. I set 179s, it's OK. I set 181s, it doesn't work, I means that doggle can't detect it at all. By the way, I commented sd_power_system_off() in on_ble_evt().

This happens because the advertising is setup to have a timeout of 180 s (3 minutes), and in the on_ble_evt() method, the chip is put in system off when this occurs. In system off, everything is turned off, and the clock hence stops.

Please note that the chip doesn't reset before you actually wake it up again; it will just stay in system off waiting for a reset or a GPIO configured with SENSE is set.
