The chip should only reset if it enters SYSTEM OFF during debugging (it will run "Emulated System OFF mode" as described in reference manual), as this will generate an error which will reset the chip, or if the chip is waken from System OFF by one of the wakeup sources.

Adding a while(1) after entering System OFF in sleep_mode_enter() (before APP_ERROR_CHECK) should prevent the chip from resetting due to an error code.

Hello Jorgen. Thanks for the help. In the case, have so way to avoid the chip restart? I see an example that make a way to avoid the micro reset. If you have some example about this.

Again, thanks for the help. I remove the sleep_mode_enter() and works.

Hi,

By default, the BLE examples have set the advertising duration to 180 seconds. When the advertising becomes idle, the chip will enter SYSTEM OFF mode.

This can be controlled in the application:

Set APP_ADV_DURATION to 0 to disable timeout and advertise forever.
Remove call to sleep_mode_enter() in case BLE_ADV_EVT_IDLE in function on_adv_evt(). This will prevent the chip from going to System OFF sleep mode, but advertising will end after 3 minutes.

Best regards,
Jørgen
