PWM Modul crash after start advertising.

Hi does no one have an idea what a reason for a crash could be? My Problem is, if i press my off button (doesn't matter if i use app_button or using gpiote) a timer is started. If the timer is finished it calls the button timeout handler which is a "System_off Function" And if i call In the Function a function which turn on the PWM (like set_pwm (128)) or if i use my wait function (using app_timer to wait some milliseconds) th processor crashes and doesn#t reset the System like i need.

What reason could it have the this happens?

best regards Nils Minor

Do i have to look for something special to use gpiote, becaouse i think that the gpiote makes some errors in my Code.

Hi, i just checked my code again and found, It its maybe not beacouse of the softdevice, maybe its becaouse of me gpiote handle. If i call the Gpiote interrupthandler the pressing the button no pwm and no delay (delay with the apptimer) works.here is my code


void gpiote_init									(void)											// Initialisierung des GPIOTE Moduls
{
		uint32_t err_code;
	
    uint32_t pin_mask1 = (1 << BUTTON_EIN);
		uint32_t pin_mask2 = (1 << BUTTON_AUS);
	
	  APP_GPIOTE_INIT(APP_GPIOTE_MAX_USERS);
    NVIC_SetPriority(GPIOTE_IRQn, APP_IRQ_PRIORITY_HIGH);

    // We want to be notified both on rising and falling edge. 
    err_code = app_gpiote_user_register(&m_gpiote_user_id_ein, pin_mask1, pin_mask1, gpiote_event_handler_ein);
    APP_ERROR_CHECK(err_code);
    
		err_code = app_gpiote_user_register(&m_gpiote_user_id_aus, pin_mask2, pin_mask2, gpiote_event_handler_aus);
    APP_ERROR_CHECK(err_code);
	
    err_code = app_gpiote_user_enable(m_gpiote_user_id_ein);
    APP_ERROR_CHECK(err_code);
	
	  err_code = app_gpiote_user_enable(m_gpiote_user_id_aus);
    APP_ERROR_CHECK(err_code);	
	
		uartStr("\n** GPIO Task Events erstellt                **");

		// NRF_GPIOTE->INTENSET = GPIOTE_INTENSET_PORT_Msk;
    // NVIC_EnableIRQ(GPIOTE_IRQn);
}

// The button eventhandler for shortpress 
void button_ein_short_pressed			(void * p_context)					// Timeouthandler für createTimerforGPIO
{ 	
	if (device_status == true && bt_ein_enable == true) 		// Ist das Gerät an?
	{	
		app_timer_stop 	(m_timer_id_ein_long_push);			// Timer wird angehalten 
	
		if (bt_count != bom_config_stat.TherapieIntensiSchritte)
		{
			bt_count++;
			uartStr("\n** Taster |Ein +| wurde gedrueckt           **");
		}
		else
		{
			uartStr("\n** Maximaler Tasterwert erreicht            **");
		}
	}
	else													// Ansonsten muss 2 Skeunden lang gedrückt werden
	{
		uint32_t err_code;
			
		err_code = app_timer_start(m_timer_id_ein_long_push, BUTTON_LONG_PRESSED, NULL);
		APP_ERROR_CHECK(err_code);
	}
}

Maybe a reason for crashing could also bee, that i use 2 giote members for handl my two buttons.
