Android 2.0上使用蓝牙通信

核心提示：1.服务器端：//请从http://www.uuidgenerator.com上获取你自己的UUIDUUID uuid = uuid.fromString(”27648B4D-D854-5674-FA60E4F535E44AF7″);BluetoothAdapter adapter = BluetoothAdapter

1.服务器端：

//请从http://www.uuidgenerator.com上获取你自己的UUID

UUID uuid = uuid.fromString(”27648B4D-D854-5674-FA60E4F535E44AF7″);

BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();

BluetoothServerSocket serverSocket = adapter.listenUsingRfcommWithServiceRecord(”MyBluetoothApp”, uuid);

// blocks until a connection is accepted

BluetoothSocket socket = serverSocket.accept();

// close the listening socket ? does not close the connected client socket

serverSocket.close();

2.客户端

// UUID of server socket

UUID uuid = uuid.fromString(“27648B4D-D854-5674-FA60E4F535E44AF7″);

BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();

// BT MAC address of server

BluetoothDevice device = adapter.getRemoteDevice(“00:11:22:33:44:55″);

BluetoothSocket socket = device.createRfcommSocketToServiceRecord(uuid);

adapter.cancelDiscovery();

// blocks until connection established

adapter.connect();

3.双方连接上后，就开始读写了

InputStream in = socket.getInputStream();

OutputStream out = socket.getOutputStream();

out.write(…);

in.read(…);

…

in.close();

out.close();

socket.close();
