The BKPT instruction represents a breakpoint, so I guess it is you that halted the execution by setting a breakpoint? Anyway it is difficult to guess anything about your implementation without more details. It may be a good idea to do things in steps, so that you know how to advertise, use timers and use GPIOTE separately. Then combining it should be straightforward.

Hi Einar, thank you for reply.

I made a code as you show, but I have a problem now.

My app does not advertising when i enable the code app_gpiote_user_register().

Stopping at BKPT 0xAB I checked on Keil debugger then.

If disable GPIOTE (no use app_gpiote_user_register()), i can see advertising when i call sd_ble_gap_adv_start().

I dont know what is the cause.

This should be straightforward. You can call sd_ble_gap_adv_start() to start advertising when the event that should trigger it occurs (a pin change using GPIOTE in your case). Then you can use a timer (I suggest that you use the application timer), and call sd_ble_gap_adv_stop() when the timer times out.
