issue in start and stop advertising

[ps_anu]

Hi, 

I am using nRF52832 , and sdk 15.2 version. I am trying the start the advertisement using timer , once it is connected it should send the data , and should disconnect. start and stop advertising is working with respect to the timer but my data is not receiving in the nRF toolbox app . why ? have a look at my code , correct me if were wrong . Led part is working fine which is declared in the timer_sensor_event_handle(), only the data i am not receiving 

static void timer_sensor_event_handler()
{

advertising_start();


 nrf_delay_ms(10000);

 nrf_gpio_pin_toggle(18);

  ble_nus_data_send(&m_nus, "hello", 25, m_conn_handle);
 nrf_delay_ms(10000);
sd_ble_gap_adv_stop(m_adv_handle);


}

 You should check what is returned by ble_nus_data_send(). There is an error in your application if it's nonzero.

how to check that ?

    static uint8_t test_array[] = {"hello"};
    static uint16_t lengde = sizeof(test_array);
    err_code = ble_nus_data_send(&m_nus, test_array, &lengde, m_conn_handle);
    APP_ERROR_CHECK(err_code);

Also, initialize the data_buffer with the data that you would want to send before the function call.
