[Prasad Kesarkar]

I am making a Bluetooth connection to a device. I have used this library for connection.

It gives problem in Android 5.0 and above specially when the screen the is locked. I get the following error in logcat

After this error I get java.io.IOException: read failed, socket might closed or timeout, read ret: -1 .

I am stuck terribly. Thanks in advance for help.
