I have enabled Bluetooth on my Pi 3 and connected phone and laptop successfully. When I try to connect my Apple or Logitech keyboard it says failed to connect on pairing. I've tried via terminal and UI. Any ideas?
I also struggled with this, but finally got my Apple keyboard to connect. See the following
bluedevil. It took quite a while to install, and after the event could not find. From the Run menu I found bluedevil-wizard, which I ran, and successfully connected my keyboard.
