Problem with advertising reset

[AndrzejB]

Hi, I try to turn off the advertising after the first connection and then turn it on after pressing the button, this is what I wrote:

void radio_notification_evt_handler(bool radio_evt)
{
    if (radio_evt)
    {
		//radio going active
		LEDS_INVERT(BSP_LED_1_MASK);
		if (connection_occurance) sd_ble_gap_adv_stop();
    } 
}

//

void GPIOTE_IRQHandler(void)
{
		printf("Are you here?");
		ble_advertising_start(BLE_ADV_MODE_FAST);
		if(NRF_GPIOTE->EVENTS_PORT)
                   		NRF_GPIOTE->EVENTS_PORT = 0;
}

Program comes to the handler of button interrupt but there the program is crashing. This problem is quite suprising for me, because I reset advertising in other application and there it's work well. Only difference is that in the other case I turn off and immediately turn on advertising, and in this application I wait for button.

As far as i know, advertising is automatically stopped after connection. You sure you need to stop it manually?

Yes, you are right, my mistake. Function ble_advertising_on_ble_evt in ble_evt_dispatch starts the advertising after connection end and after I remove this function I don't need to stop advertising manually. However, I still can't start advertising in GIOTE_IRQHandler, and I don't know why. Beneath I placed sys_evt_dispatch and ble_evt_dispatch, maybe there is a reason why it not working (in fact I have trouble to fully understand these functions, particularly when these functions are calling)

static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
{
    dm_ble_evt_handler(p_ble_evt);
    ble_conn_params_on_ble_evt(p_ble_evt);
    on_ble_evt(p_ble_evt);
    ble_our_service_on_ble_evt(&m_our_service, p_ble_evt);
}


static void sys_evt_dispatch(uint32_t sys_evt)
  {
        pstorage_sys_event_handler(sys_evt);
        ble_advertising_on_sys_evt(sys_evt);
        if (sys_evt == NRF_EVT_POWER_FAILURE_WARNING)
        {
    	sd_power_dcdc_mode_set(NRF_POWER_DCDC_DISABLE);
        }
    }
