Default BT Keyboard - how to?

Hey Guys

i bought this BT Keyboard :

It works on Windows Mobile without any "driver", but on every android version atm it don't works (i can just pair it)

There is an App for the Android (on the driver disk of the keyboard), but this don't work -.- even on the Produkt Page is written: "Google Android(1.6+)" bad joke -.-

Already tried "elbrain.bluekeyboard.ime (free version)" but after it tries with "Connecting..." some seconds later it displays "Disconnected."

Does anyone has the same BT Keyboard, and got it work?
