I'am trying to connect my Android App with a bluetooth Keyboard using the bluetooth tutorial.
When I run the app, I see the messages:

'Searching for devices,.
1 device found then Bluetooth keyboard,

Trying to connect to: Bluetooth keyboard (DC:2C:.......) read failed, socket might closed or timeout, read ret: -1

Could you please help me?

Thank You
