Microsoft Surface Ergonomic Bluetooth Keyboard paired but not working

[fernqandoamat]

Hi all,

I have Linux Lite 3.2 64-bit installed in an Intel NUC6i5SYK. Everything worked out of the box great except for one thing: Microsoft Surface Ergonomic Bluetooth Keyboard. Linux lite seems to pair the keyboard correctly as you can see from the output of bluetoothctl info:

[bluetooth]# info F1:8D:75:97:13:1B
Device F1:8D:75:97:13:1B
  Name: Ergonomic Keyboard
  Alias: Ergonomic Keyboard
  Appearance: 0x03c1
  Icon: input-keyboard
  Paired: yes
  Trusted: yes
  Blocked: no
  Connected: yes
  LegacyPairing: no
  UUID: Generic Access Profile    (00001800-0000-1000-8000-00805f9b34fb)
  UUID: Generic Attribute Profile (00001801-0000-1000-8000-00805f9b34fb)
  UUID: Device Information        (0000180a-0000-1000-8000-00805f9b34fb)
  UUID: Battery Service          (0000180f-0000-1000-8000-00805f9b34fb)
  UUID: Human Interface Device    (00001812-0000-1000-8000-00805f9b34fb)

However, when I press any key nothing happens. A few suspicious things:
-The LED light on the keyboard keeps blinking even after the pairing (usually once it is paired it stops)
-The bluetooth wizard (or the bluetoothctl terminal commands) never asked for a PIN

The keyboard works pairing it with my MacOS laptop, so that should not be a problem. Any ideas what could be wrong?

Thanks,
Fernando
