Android Zebra Scanner Connection Issue reg.,

I am getting an error when i am trying to connect to Zebra Scanner through Bluetooth connection. From the SDK that zebra has provided was throwing an error message "Could not connect to device: read failed, socket might closed or timeout, read ret: -1"

The same with the app downloaded from the Google Play Store and tried to connect the scanner and the same error was observed.

Both the Device Scanner and Zebra Scanner Bluetooth was turned on.
