Device getting restart after advertising_start() function

[subodh]

Hi, I am using following code inside for(;;) in main function

if(diff == 30) 	
    advertising_stop();
else if(diff == 60)
    advertising_start();

Following are the advertising_start and advertising_stop function

static void advertising_start(void) {
    uint32_t err_code;

    err_code = sd_ble_gap_adv_start(&m_adv_params);
    APP_ERROR_CHECK(err_code);

    err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING);
   APP_ERROR_CHECK(err_code);
}

static void advertising_stop(void) { 	
   uint32_t err_code;
   err_code = sd_ble_gap_adv_stop(); 	
   APP_ERROR_CHECK(err_code);

   err_code = bsp_indication_set(BSP_INDICATE_IDLE); 	
   APP_ERROR_CHECK(err_code); 
}

advertising_stop(); works properly when diff(time difference) reaches 30. but when diff reaches 60 and advertising_start() is called then device gets reset. What may be the reason behind this?

I am new to development framework, please guide me on this issue.

Most likely the device is not advertising when you call sd_ble_gap_adv_stop(), and in that case it will return NRF_ERROR_INVALID_STATE.

Thank you Einar, I wait to start advertising after the disconnection event then I stopped the advertising. i.e BLE_GAP_EVT_DISCONNECTED leads to advertising start and later we can stop advertising. i.e once it comes to known state we can change state to advertising stop. Isn't it?
