B3 bluetooth keyboard

I bought an Anker bluetooth keyboard for my B3 piPad, and have spent 10 days periodically swearing at it trying both the CLI or GUI app.  Finally, I found a complete set of instructions on the RPi forum that worked.  Type following commands from a console:

  1. bluetoothctl
  2. pairable on
  3. scan on
    Now you have to wait, until your BT device (keyboard) is shown (don’t forget to activate your keyboard now! Press the so called “pairing button” of your BT keyboard, may be a combination of two keys, see the users manual!). Don’t forget to wait!!! You should see it’s address as “xx:xx:xx:xx:xx:xx”
  4. scan off
  5. agent on
  6. pair xx:xx:xx:xx:xx:xx
    Now you are requested to input a number (6 digits) using your BT keyboard, and then you have to quit it by pressing the “return” button of your BT keyboard! “pairing successful” should be displayed!
  7. trust xx:xx:xx:xx:xx:xx
  8. connect xx:xx:xx:xx:xx:xx
    “connection successful” should be displayed!
  9. info xx:xx:xx:xx:xx:xx
    … will show the success again (some Information are displayed).
  10. exit

Reboot your RPi now.
