required Bluetooth ON and OFF functions in "ble_app_uart" example

Hi,

I want to write Bluetooth ON and OFF functions for the project purpose,

what are all the steps needs to follow while creating ON function and same for OFF function.

Thanks in advance

Kind Regards,

Thiru.

  • HI Kenneth,

    Thank you for the reply,

    sd_ble_gap_disconnect(m_conn_handle, BLE_GAP_EVT_ADV_SET_TERMINATED);
    sd_ble_gap_adv_stop(m_advertising.adv_handle);

    I have tried both calls, but the bluetooth discovery is not stoped

    Need to follow any sequence?

    Thank you for the support.

  • What is the return code for those two calls? Also, it may be that the application is setup in a BLE callback that when the link is disconnected, that the application should start advertisement again, so look for that.

    Best regards,
    Kenneth

  • Hi Henry_Chou

    I tried lots of time but i am not able to ON and OFF 

    Receive data via UART data_array[].It get's OFF but not getting ON i don't have Idea

    void uart_event_handle(app_uart_evt_t * p_event)
    {
    static uint8_t data_array[BLE_NUS_MAX_DATA_LEN];
    static uint8_t index = 0;
    uint32_t err_code;
    /****************************************************************/
    if(data_array[0] == '1')
    {
         // ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
         ble_advertising_restart_without_whitelist(&m_advertising);

    }
    else if(data_array[0] == '2')
    {
         sleep_mode_enter();
    }
    /****************************************************************/
    switch (p_event->evt_type)
    {
    case APP_UART_DATA_READY:
    UNUSED_VARIABLE(app_uart_get(&data_array[index]));
    index++;
    if ((data_array[index - 1] == '\n') ||
    (data_array[index - 1] == '\r') ||
    (index >= m_ble_nus_max_data_len))
    {
    if (index > 1)
    {
    NRF_LOG_DEBUG("Ready to send data over BLE NUS");
    NRF_LOG_HEXDUMP_DEBUG(data_array, index);

    do
    {
    uint16_t length = (uint16_t)index;
    err_code = ble_nus_data_send(&m_nus, data_array, &length, m_conn_handle);
    if ((err_code != NRF_ERROR_INVALID_STATE) &&
    (err_code != NRF_ERROR_RESOURCES) &&
    (err_code != NRF_ERROR_NOT_FOUND))
    {
    APP_ERROR_CHECK(err_code);
    }
    } while (err_code == NRF_ERROR_RESOURCES);
    }

    index = 0;
    }
    break;

    case APP_UART_COMMUNICATION_ERROR:
    APP_ERROR_HANDLER(p_event->data.error_communication);
    break;

    case APP_UART_FIFO_ERROR:
    APP_ERROR_HANDLER(p_event->data.error_code);
    break;

    default:
    break;
    }
    }
