[quote user="metcenger"]Do you mean that in the event BLE_ADV_EVT_IDLE instead of go to sd_power_system_off() func, should I run app timer and after it goes off, run advetrising again?[/quote]

For instance yes, or any other action you want to do when the timer goes off.

Thanks. I able to run app timer. But I can't understand what do you mean.

Yes, after advertising time elapsed, I go to the sd_power_system_off(); function.

Do you mean that in the event BLE_ADV_EVT_IDLE instead of go to sd_power_system_off() func, should I run app timer and after it goes off, run advetrising again?

Hello,

You will notice that on advertisment timeout that there is BLE_ADV_EVT_IDLE event in on_adv_evt() for most BLE peripheral examples. Typically the chip then go to system OFF state by calling sd_power_system_off(). In your case you must remove sd_power_system_off(), and instead start an app_timer with a 30second timeout, on app_timer timeout you can for instance start advertisement again (or do other action). You should find several examples that show how to define, create, and start app timer.
