my data is not transferring

[ps_anu]

hi... 

i want to check how the sleep mode is working so i am testing with the simple uart program 

here you can see the code .. ble_nus is not sending the data in ble_uart app

please help me out ... too confused

 */
int main(void)
{
    bool erase_bonds;

    // Initialize.
    uart_init();
    log_init();
    timers_init();
    buttons_leds_init(&erase_bonds);
    power_management_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();
    uint16_t i;

    // Start execution.
    printf("\r\nUART started.\r\n");
    NRF_LOG_INFO("Debug logging for UART over RTT started.");
    advertising_start();
  // Enter main loop.

    for(i=0;i<5;i++)
    {
    ble_nus_data_send(&m_nus, "kd", 4, m_conn_handle);
    power_manage();
   
    
    }
}
