ble_uart problem with dfu

[djqtsg]

Hardware (HW)

• BMD 350 evaluation board, equivalent to PCA10040

Software

• nRF5 SDK 12.0. Keil uVersion 5 IDE.

• SoftDevice: s132_nrf52_3.0.0_softdevice.hex

• Firmware application (FA): nRF5_SDK_12.0.0_3bcc1f7\examples\ble_peripheral\experimental_ble_app_buttonless_dfu

Modified dfu main.c:

1. Add uart service init code to service_init after dfu service init
2. Add nus_data_handler to handle data received from BLE

Compiling OK, firmware flashing OK and running.

From Android "nRF Toolbox", I can see both dfu and uart services and connect device with UART panel. However, when I try to send text to device, nus_data_handler is not triggered.

You're not dispatching the BLE events to the NUS BLE event handler, you need to add the ble_nus_on_ble_evt() event handler to the ble_evt_dispatch() function in main.c

static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
{
    ble_conn_state_on_ble_evt(p_ble_evt);
    pm_on_ble_evt(p_ble_evt);
    ble_conn_params_on_ble_evt(p_ble_evt);
    bsp_btn_ble_on_ble_evt(p_ble_evt);
    on_ble_evt(p_ble_evt);
    ble_advertising_on_ble_evt(p_ble_evt);
    ble_dfu_on_ble_evt(&m_dfus, p_ble_evt);

    /* Add Missing NUS BLE event handler */
    ble_nus_on_ble_evt(&m_nus, p_ble_evt);
}

thanks. it's working now!
