实现一个android服务，通过蓝牙读取Arduino上的按钮传感器输入

我正在尝试将Arduino 101上的按钮传感器连接到Android应用程序

其想法是实现一个应用程序，该应用程序连接到Arduino上的蓝牙硬件按钮，然后在后台运行一个服务，不断监听蓝牙广播。如果点击按钮，蓝牙信号将通过Arduino传输，服务应捕获该信号并打开应用程序

我使用Android的蓝牙通用属性配置文件（GATT）官方文档将任意数据从Arduino传输到后台服务。我的服务能够连接到蓝牙信号并断开连接，但无法检测到按钮的点击

谁能帮帮我吗

这是蓝牙侦听器服务的代码

private final BluetoothGattCallback mGattCallback = new      BluetoothGattCallback() {
        @Override
        public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
            String intentAction;
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            intentAction = ACTION_GATT_CONNECTED;
            mConnectionState = STATE_CONNECTED;
            broadcastUpdate(intentAction);
            Log.i(TAG, "Connected to GATT server.");
            // Attempts to discover services after successful connection.
            Log.i(TAG, "Attempting to start service discovery:" +
                    mBluetoothGatt.discoverServices());

        } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            intentAction = ACTION_GATT_DISCONNECTED;
            mConnectionState = STATE_DISCONNECTED;
            Log.i(TAG, "Disconnected from GATT server.");
            broadcastUpdate(intentAction);
        }
    }

    @Override
    public void onServicesDiscovered(BluetoothGatt gatt, int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) {
            broadcastUpdate(ACTION_GATT_SERVICES_DISCOVERED);
        } else {
            Log.w(TAG, "onServicesDiscovered received: " + status);
        }
    }

    @Override
    public void onCharacteristicRead(BluetoothGatt gatt,
                                     BluetoothGattCharacteristic characteristic,
                                     int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) {
            broadcastUpdate(ACTION_DATA_AVAILABLE, characteristic);

        }
    }

    @Override
    public void onCharacteristicChanged(BluetoothGatt gatt,
                                        BluetoothGattCharacteristic characteristic) {
        broadcastUpdate(ACTION_DATA_AVAILABLE, characteristic);
    }
};

private void broadcastUpdate(final String action) {
    final Intent intent = new Intent(action);
    sendBroadcast(intent);
}

private void broadcastUpdate(final String action,
                             final BluetoothGattCharacteristic characteristic) {
    final Intent intent = new Intent(action);
    final byte[] data = characteristic.getValue();
    if (data != null && data.length > 0) {
            final StringBuilder stringBuilder = new StringBuilder(data.length);
            for(byte byteChar : data)
                stringBuilder.append(String.format("%02X ", byteChar));
        System.out.println(stringBuilder);
            intent.putExtra(EXTRA_DATA,"\n" + stringBuilder.toString());
    }
    sendBroadcast(intent);
}

以下是另一个服务中的BroadcastReceiver。这两个服务正在相互通信

 private final BroadcastReceiver mGattUpdateReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();
        if (BluetoothLeService.ACTION_GATT_CONNECTED.equals(action)) {
            mConnected = true;
        } else if (BluetoothLeService.ACTION_GATT_DISCONNECTED.equals(action)) {
            mConnected = false;

        } else if (BluetoothLeService.ACTION_GATT_SERVICES_DISCOVERED.equals(action)) {
            // Show all the supported services and characteristics on the user interface.
            displayGattServices(mBluetoothLeService.getSupportedGattServices());

        } else if (BluetoothLeService.ACTION_DATA_AVAILABLE.equals(action)) {
           System.out.println(intent.getStringExtra(BluetoothLeService.EXTRA_DATA));

        }
    }
};

嘿，连接正常吗？你能在arduino和android之间发送数据吗？您能串行打印从Android传输的任何数据吗？是的，Arduino代码正在工作。我可以在Android活动中传输arduino的数据，但不能在服务中传输。嘿，连接正常吗？你能在arduino和android之间发送数据吗？您能串行打印从Android传输的任何数据吗？是的，Arduino代码正在工作。我可以在Android活动中传输arduino的数据，但不能在服务中传输。
