我正在尝试从我的Android手机（三星galaxy s2）发送一个“helloWorld”（只是一个字符串）到运行linux的PC上的python脚本。但我无法让它工作。以下是android应用程序（客户端）和python脚本（服务器）的代码。蓝牙在PC和手机上工作正常（例如，我可以通过BT从手机发送照片）。当我调用btSocket.connect（）;在下面的java代码中，它只是不会连接。我是否必须指定要连接到的端口，因为我已为 serverSocket 指定了端口？任何帮助将不胜感激。

public class BlueTooth_testActivity extends Activity {
    TextView header;
    Button discoverDevicesBtn;
    Button sendMsgBtn;
    Button closeBtn;
    EditText sendTxt;
    BluetoothAdapter btAdapter;
    BluetoothSocket btSocket;
    private static String btAdress = "00:10:60:D1:95:CD";
    private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
    private OutputStream out;
    public BluetoothDevice device;
    private Boolean CONNECTED = false;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //init layout parameters        
        header = (TextView) findViewById(R.id.text1);
        discoverDevicesBtn = (Button) findViewById(R.id.discBtn);
        sendMsgBtn = (Button) findViewById(R.id.sendButton);
        closeBtn = (Button) findViewById(R.id.closeButton);
        sendTxt = (EditText) findViewById(R.id.editText1);
        discoverDevicesBtn.setOnClickListener(discoverDeviceListener);
        sendMsgBtn.setOnClickListener(sendMsgListener);
        closeBtn.setOnClickListener(closeBtnListener);
        //init bluetooth
        btAdapter = BluetoothAdapter.getDefaultAdapter();
        if (btAdapter.isEnabled()) {
            Toast.makeText(this, "Bluetooth state:" + btAdapter.getState() + " Ok!", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "Bluetooth state:" + btAdapter.getState() + " Not ok!", Toast.LENGTH_LONG).show();
        }

    }

    private Button.OnClickListener discoverDeviceListener = new Button.OnClickListener() {@Override
        public void onClick(View v) {
            if (!CONNECTED) {
                device = btAdapter.getRemoteDevice(btAdress);
                header.append("\nRemote device: " + device.getName());
                try {
                    btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
                } catch (Exception e) {
                                    }
                header.append("\n createRfcommsockettoservice! ");
                btAdapter.cancelDiscovery();
                try {
                    btSocket.connect();
                    CONNECTED = true;
                    header.append("\n btSocket Created!");
                } catch (IOException e) {
                    Toast.makeText(getApplicationContext(), "Could not connect to socket", Toast.LENGTH_LONG);
                    try {
                        btSocket.close();
                    } catch (Exception b) {}
                }
            }

        }
    };


    private Button.OnClickListener sendMsgListener = new Button.OnClickListener() {@Override
        public void onClick(View v) {
            if (CONNECTED) {
                try {
                    out = btSocket.getOutputStream();
                    String msg = sendTxt.getText().toString();
                    byte[] msgBffr = msg.getBytes();
                    out.write(msgBffr);
                    Toast.makeText(getApplicationContext(), "Message sent", Toast.LENGTH_LONG).show();
                } catch (Exception a) {
                    Toast.makeText(getApplicationContext(), "Could not send msg", Toast.LENGTH_LONG).show();
                }
            } else {
                Toast.makeText(getApplicationContext(), "cant send msg, not connected", Toast.LENGTH_LONG).show();
            }

        }
    };


}  

（我没有费心去包含其余的java代码，因为问题出在连接设置的某个地方）

import bluetooth

name="bt_server"
target_name="siggen"
uuid="00001101-0000-1000-8000-00805F9B34FB"

def runServer():
serverSocket=bluetooth.BluetoothSocket(bluetooth.RFCOMM )
    port=bluetooth.PORT_ANY
    serverSocket.bind(("",port))
    print "Listening for connections on port: ", port   
    serverSocket.listen(1)
    port=serverSocket.getsockname()[1]
    inputSocket, address=serverSocket.accept()
    print "Got connection with" , address
    data=inputSocket.recv("1024")
    print "received [%s] \n " % data    
    inputSocket.close()
    serverSocket.close()  

runServer()
