Question

我正在开发一个简单的蓝牙应用程序，我想发送短信。在尝试配对设备时遇到问题，它会抛出异常“java.io.IOException：Service discovery failed”。有关详细信息，我将在此处发布代码。在LG手机Android 2.3.3上移植应用程序

private static final UUID MY_UUID = UUID.fromString("00000003-0000-1000-8000-00805F9B34FB");
BluetoothDevice btDevice = BluetoothActivity.btDevices.get(position).getBtDevice();

clientSocket = btDevice.createRfcommSocketToServiceRecord(MY_UUID);

//Method m = btDevice.getClass().getMethod("createRfcommSocketToServiceRecord", new Class[] { UUID.class } );                   
//clientSocket =(BluetoothSocket) m.invoke(btDevice, MY_UUID);

//Method m = btDevice.getClass().getMethod("createRfcommSocket",new Class[] { int.class }); 
//clientSocket =(BluetoothSocket) m.invoke(btDevice, 1);

if(clientSocket!=null)
{

    if(BluetoothActivity.btAdapter.isDiscovering()){
        BluetoothActivity.btAdapter.cancelDiscovery();

}
//facing issue during paring                        
clientSocket.connect();

tmpOut = clientSocket.getOutputStream();
tmpOut.write("HelloWorld.txt".getBytes());
if(tmpOut!=null){
    tmpOut.close();
}   
}

感谢任何形式的帮助，

尝试使用此UUID：

fa87c0d0-afac-11de-8a39-0800200c9a66

出于某种原因，这是我唯一可以上班的UUID ......我不知道为什么。
