[Nawual]

Hello everyone, I want to make a pedal to be able to pass the sheets in android. I have read several post in the forum and I would like to use a mouse bluetooh, dismantle it and with the circuit put it on a pedal of a two-button electric keyboard.
I've tried before anything, see if I can with a mouse bluetooh pass the pages but it does not work despite being connected to the tablet.
  My question is if it does not work because it is the Android version of the program or because it is not configured well on the tablet.
  In the settings of the program I have seen that there are options to configure a mouse but it is usb.
  Let's see if you can help me. Thanks
