iPazzPort mini-keyboard Bluetotth connection

I just paired my new iPazzPort with Bluetooth on my Raspberry Pi 2. However, when I try to use it, nothing happens.
Wired input devices (leyboard + mouse) work well.
Even after restart, with wired input devices connected or not, when I press a key, there is just the blue light flashing on the keyboard + the red light flashing on the receiver, but on the screen nothing happens; mousepad seems inactive too.
Does anybody know how to do it right? Please help. :cry:

In My OSMC, check the section Remotes and verify it is not a problem, also check input devices on settings
