服务发现失败android蓝牙

Question

我正在开发一个代码，以便与来自Micromax Tab的自定义蓝牙电路进行通信。直到套接字创建它工作正常。但是，当我尝试连接失败时，说服务发现失败或主机关闭。我尝试了所有可能的提到这个主题的帖子，提到了同样的问题。但最终得到同样的错误。我试图改变UUID，但没有任何作用。任何线索？ 下面是我的代码：

final BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); 
     if (mBluetoothAdapter == null) { 
       Toast.makeText(this, "Bluetooth not found",Toast.LENGTH_LONG).show(); 
     } 

     if (!mBluetoothAdapter.isEnabled()) { 
      Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); 
      startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT); 
     } 

     Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices(); 
    // If there are paired devices 
    if (pairedDevices.size() > 0) { 
     // Loop through paired devices 
     for (BluetoothDevice device : pairedDevices) { 
      // Add the name and address to an array adapter to show in a ListView 
      if(device.getName().equals("linvor")) 
      { 
       mmDevice = device; 
       Toast.makeText(this, "Name: " + device.getName() + " And Address: " + device.getAddress(),Toast.LENGTH_LONG).show(); 
      } 

     } 
    } 
    mBluetoothAdapter.cancelDiscovery(); 
    BluetoothSocket tmp = null; 
    // UUID uuid = UUID.fromString("00001105-0000-1000-8000-00805F9B34FB"); 

    // MY_UUID is the app's UUID string, also used by the server code 
     // tmp = mmDevice.createRfcommSocketToServiceRecord(uuid); 
    Method m = null; 
    try { 
     m = mmDevice.getClass().getMethod("createRfcommSocket", new Class[] {int.class}); 
     try { 
      tmp = (BluetoothSocket) m.invoke(mmDevice, 1); 
     } catch (IllegalArgumentException e) { 
      // TODO Auto-generated catch block 
      Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
     } catch (IllegalAccessException e) { 
      // TODO Auto-generated catch block 
      Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
     } catch (InvocationTargetException e) { 
      // TODO Auto-generated catch block 
      Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
     } 
    } catch (NoSuchMethodException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } 
    try { 
     tmp = (BluetoothSocket) m.invoke(mmDevice, 1); 
    } catch (IllegalArgumentException e) { 
     // TODO Auto-generated catch block 
     Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
    } catch (IllegalAccessException e) { 
     // TODO Auto-generated catch block 
     Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
    } catch (InvocationTargetException e) { 
     // TODO Auto-generated catch block 
     Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
    } 


    Toast.makeText(getBaseContext(), "Created socket",Toast.LENGTH_LONG).show(); 
    mmSocket = tmp; 
    mBluetoothAdapter.cancelDiscovery(); 
    Toast.makeText(getBaseContext(), "Discovery cancelled",Toast.LENGTH_LONG).show(); 
    try { 
     // Connect the device through the socket. This will block 
     // until it succeeds or throws an exception 
     mmSocket.connect(); 
     Toast.makeText(getBaseContext(), "Connected",Toast.LENGTH_LONG).show(); 
    } catch (IOException e1) { 
     // Unable to connect; close the socket and get out 
     Toast.makeText(getBaseContext(), e1.getMessage(),Toast.LENGTH_LONG).show(); 
     try { 
      mmSocket.close(); 
     } catch (IOException e) { 
      Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_LONG).show(); 
     } 
    }
