关于android 经典蓝牙开发 使用UUID连接的问题

先贴一下我连接的代码，有点乱

开启蓝牙连接，由于连接是耗时的，所以肯定新开一个线程去连接，以下是连接的代码`package

public class ConnectThread extends Thread {

private BluetoothDevice btd;

private BluetoothSocket bts;

private BluetoothController mController;

//00001101-0000-1000-8000-00805f9b34fb

public static final String MY_UUID = “00001101-0000-1000-8000-00805F9B34FB”;

private InputStream in;

private OutputStream out;

private static byte read_byts[] = new byte[120];

public static boolean isConnected = false;

public ConnectThread(BluetoothDevice btd) {
BluetoothSocket temp = null;
mController = new BluetoothController();
this.btd = btd;
try {
temp = btd.createInsecureRfcommSocketToServiceRecord(UUID.fromString(MY_UUID));
} catch (IOException e) {
e.printStackTrace();
}
bts = temp;
}

private static android.os.Handler handler = new android.os.Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if (msg.what == 1) {

}
}
};

@Override
public void run() {
super.run();
//取消搜索因为搜索会让连接变慢
mController.getmAdapter().cancelDiscovery();
try {
//通过socket连接设备，这是一个阻塞操作，直到连接成功或发生异常
Log.e(TAG, "run: 连接1");
Log.e(TAG, "当前线程2：" + Thread.currentThread());
// bts.connect();
bts=connectBtByChannel(btd);
Log.e(TAG, "run: 连接2");
Log.e(TAG, "run: 连接成功" );
if (bts.isConnected()) {
isConnected = true;
in = bts.getInputStream();
out = bts.getOutputStream();
}
} catch (IOException e) {
Log.e(TAG, "run: 连接3——————————————————————》" + e.getMessage());
Log.e(TAG, "run: 连接3");
//无法连接，关闭socket并且退出
System.out.println("=========拒绝");
try {

bts.close();
} catch (IOException e1) {
e1.printStackTrace();
}
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
while (isConnected) {
try {
Log.e(TAG, "当前线程：" + Thread.currentThread());
int len = in.read(read_byts);
if (len != -1) {
Message me = Message.obtain();
me.what = 1;
handler.sendMessage(me);
}
} catch (IOException e) {
e.printStackTrace();
}
}
//管理连接(在独立的线程)
// manageConnectedSocket(mmSocket);
}

/* Call this from the main activity to send data to the remote device */
public void write(byte[] bytes) {
try {
out.write(bytes);
} catch (IOException e) {
}
}

public void cancel() {
try {
bts.close();
} catch (IOException e) {
e.printStackTrace();
}
}

private static int port = 0;

/**
* 通过反射原理，使用随机端口发起蓝牙连接
*/
public BluetoothSocket connectBtByChannel(BluetoothDevice mBluetoothDevice) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException, IOException, InvocationTargetException {
Method method = mBluetoothDevice.getClass().getMethod("createRfcommSocket", new Class[]{int.class});
port = port++ % 30;
if (port == 0) {
port = 1;
}

BluetoothSocket mBluetoothSocket = (BluetoothSocket) method.invoke(mBluetoothDevice, port);//1-30端口
mBluetoothSocket.connect();//发起连接
return mBluetoothSocket;
}

/**

* */
public BluetoothSocket connectBtBySco(BluetoothDevice mBluetoothDevice) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException, IOException{
Method method = mBluetoothDevice.getClass().getMethod("createScoSocket");

BluetoothSocket mBluetoothSocket = (BluetoothSocket)method.invoke(mBluetoothDevice);
mBluetoothSocket.connect();//发起连接
return mBluetoothSocket;
}
/**未配对过的，在连接建立之前先配对
* @throws Exception */
public void createBond(BluetoothDevice mBluetoothDevice) throws Exception{
try {
// 连接建立之前的先配对
if (mBluetoothDevice.getBondState() == BluetoothDevice.BOND_NONE) {
Method creMethod = BluetoothDevice.class.getMethod("createBond");
Log.i("BluetoothManager", "开始配对");
creMethod.invoke(mBluetoothDevice);
}
} catch (Exception e) {
// TODO: handle exception
//DisplayMessage("无法配对！");
e.printStackTrace();
throw new Exception("Can't createBond with this device,please try again");
}
}

}

一开始我是使固定的UUID去获取一个BlueToothSocket

temp = btd.createInsecureRfcommSocketToServiceRecord(UUID.fromString(MY_UUID));

拿到之后进行连接

bts.connect();

但是不知道什么原因一直返回

read failed, socket might closed or timeout, read ret: -1

可能是UUID的问题吧。

然后百度一下这个问题，也有很多人都碰到过这个问题，用了其中一个人的解决办法
