Android Question Bluetooth problems

[Giuliano Cucchiarini]

Hi
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:.......)

java.io.IOException: read failed, socket might closed or timeout, read ret: -1

Could you please help me?

Thank You
Giuliano C.

The Serial library allows you to connect to devices that implement the SPP profile. Bluetooth keyboards are handled automatically by the OS.
