连接蓝牙HID设备,需要先进行蓝牙配对,然后建立蓝牙连接。以下是Android编程实现连接蓝牙HID设备的步骤:
1. 获取蓝牙适配器
```
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
```
2. 打开蓝牙
```
if (!bluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
```
3. 扫描蓝牙设备
```
bluetoothAdapter.startDiscovery();
```
4. 获取已配对设备列表
```
Set<BluetoothDevice> pairedDevices = bluetoothAdapter.getBondedDevices();
```
5. 连接蓝牙设备
```
BluetoothSocket socket = device.createInsecureRfcommSocketToServiceRecord(MY_UUID);
socket.connect();
```
其中,MY_UUID 是一个唯一标识符,它用于识别应用程序与设备之间的蓝牙通信。HID设备通常使用的是HID协议,其UUID为00001124-0000-1000-8000-00805f9b34fb。
连接成功后,您可以使用InputStream和OutputStream与设备进行通信。请注意,对于HID设备,您需要了解其通信协议并按照其协议进行通信。
