Here's some basic code snippets.
Server code
UUID uuid = uuid.fromString("27648B4D-D854-5674-FA60E4F535E44AF7"); //
generate your own UUID at http://www.uuidgenerator.com
BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
BluetoothServerSocket serverSocket =
adapter.listenUsingRfcommWithServiceRecord("MyBluetoothApp", uuid);
BluetoothSocket socket = serverSocket.accept(); // blocks until a
connection is accepted
serverSocket.close(); // close the listening socket - does not close
the connected client socket
Client code
UUID uuid = uuid.fromString("27648B4D-D854-5674-FA60E4F535E44AF7"); //
UUID of server socket
BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
BluetoothDevice device = adapter.getRemoteDevice("00:11:22:33:44:55");
// BT MAC address of server
BluetoothSocket socket = device.createRfcommSocketToServiceRecord(uuid);
adapter.cancelDiscovery();
adapter.connect(); // blocks until connection established
At this point both sides have a connected BluetoothSocket that you can go
crazy with.
InputStream in = socket.getInputStream();
OutputStream out = socket.getOutputStream();
out.write(...);
in.read(...);
...
in.close();
out.close();
socket.close();
