Post ICS版本中的藍牙連接問題

我能夠首次連接到外部成對的藍牙硬件。之後，如果我重複連接/ disconect程序有時會得到例外。Post ICS版本中的藍牙連接問題

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

，並能夠連接again.Sometimes第二審判本身多次試驗後成功

問題與設備觀察：Nexux7（版本4.3）和MotoG（奇巧）

代碼連接：

private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); 
device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(devAddress);  
socket = device.createRfcommSocketToServiceRecord(MY_UUID);

和呼叫從的AsyncTask socket.connect（）

代碼關閉插座：主題

if (in != null) { 
      Logger.loge(CLASS_NAME + "." + "resetConnection", "in != null"); 
     try { 
      in.close(); 
     } catch (Exception e) { 
      // Log.d(TAG,"exception in closing inputstream - " + e.getMessage()); 
     } 
     in = null; 
    } 
if (out != null) { 
    Logger.loge(CLASS_NAME + "." + "resetConnection", "out != null"); 

    try { 
     out.close(); 
    } catch (Exception e) { 
     // Log.d(TAG,"exception in closing outputstream - " + e.getMessage()); 
    } 

    out = null; 
} 
if (socket != null) { 
    Logger.loge(CLASS_NAME + "." + "resetConnection", "socket != null"); 

    try { 
     socket.close(); 
    } catch (Exception e) { 
     //Log.d(TAG,"exception in closing socket - " + e.getMessage()); 
    } 
    socket = null; 
}
