android bluedroid怎样进行蓝牙通信

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

if (!bluetoothAdapter.isEnabled()) {
    // 提示用户打开蓝牙或检查蓝牙设置
}

bluetoothAdapter.startDiscovery();
// 注册回调方法
bluetoothAdapter.setDiscoveryListener(new BluetoothAdapter.DiscoveryListener() {
    @Override
    public void onDiscoveryStarted(int filter) {
        // 搜索开始时的处理
    }

    @Override
    public void onDiscoveryStopped(int filter) {
        // 搜索结束时的处理
    }

    // 其他回调方法...
});

Set<BluetoothDevice> bondedDevices = bluetoothAdapter.getBondedDevices();
if (bondedDevices.size() > 0) {
    // 遍历已配对设备列表
    for (BluetoothDevice device : bondedDevices) {
        // 获取设备名称和地址
        String deviceName = device.getName();
        String deviceAddress = device.getAddress();
        // 你可以在这里根据设备名称或地址进行进一步的操作
    }
}

BluetoothSerialPortAdapter bluetoothSerialPortAdapter = new BluetoothSerialPortAdapter(context);
bluetoothSerialPortAdapter.connect(remoteAddress); // 远程设备的MAC地址

InputStream inputStream = bluetoothSerialPortAdapter.getInputStream();
OutputStream outputStream = bluetoothSerialPortAdapter.getOutputStream();

inputStream.close();
outputStream.close();
bluetoothSerialPortAdapter.disconnect();
