android蓝牙连接错误(读取失败的套接字可能关闭或超时)

我想从Android设备中的应用程序连接到远程设备(配对).远程设备是HC-05模块.
我的代码是:

UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); //Standard SerialPortService ID

try {
    mSocket = MyDevice.createRfcommSocketToServiceRecord(uuid);
} catch (IOException e) {
    Toast.makeText(this, "S", Toast.LENGTH_SHORT).show();
}  

ba.cancelDiscovery();

try {
    mSocket.connect();
} catch (IOException e){
    Toast.makeText(this, e.getLocalizedMessage(), Toast.LENGTH_SHORT).show();

    Log.e("YOUR_APP_LOG_TAG1", "I got an error", e);
}

try {
    mOutputStream = mSocket.getOutputStream();
    mInputStream = mSocket.getInputStream();
} catch (IOException e) {
    Toast.makeText(this, "io", Toast.LENGTH_SHORT).show();
}

Run Code Online (Sandbox Code Playgroud)

但我在行mSocket.connect()中遇到错误.

错误:
