Thank you! I changed priority to 3 and now everything works fine :)

I am not familiar with advertising module (i just don't use it to advertise), but i think this is because you cannot call SVC from higher priority context. I assume your GPIOTE IRQ have higher priority than SVC, so it causes hardfault. You just have to leave somehow from interrupt context (just set a flag in irq handler?) and start advertising by checking the flag. about ble_evt_dispatch and sys_evt_dispatch - they are used to propagate BLE and SOC events in app, you can read about it here and here

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);
        }
    }

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