After reflecting this bug it may be better to start this as a question.
Perhaps there is a simple solution that I haven't found yet. Sorry for
the circumstances.

Title:
  Connection to Microsoft Designer Keyboard not possible

Status in bluez package in Ubuntu:
  Invalid

Bug description:
  Hello,

  I'm trying to connect my Dell XPS 13 9343 to the Microsoft Designer
  keyboard and mouse (Bluetooth 4.0).

  Via the GUI Tools I'm unable to connect any bluetooth device
  unfortunately. At least using bluetoothctl I managed to connect an old
  Logitech bluetooth mouse.  When trying to connect the Microsoft mouse
  for example the tool returns that the connection was successful
  always.

  [Designer Mouse]# connect C2:01:31:4D:2A:06 
  Attempting to connect to C2:01:31:4D:2A:06
  Connection successful
  [CHG] Device C2:01:31:4D:2A:06 Connected: no
  [CHG] Device C2:01:31:4D:2A:06 Connected: yes

  Unfortunately it is not useable afterwards. I also tried to trust or
  pair it beforehand which didn't change anything.

  The syslog shows the following.

  Jan 26 19:37:53 avion kernel: [  435.845874] NET: Registered protocol family 38
  Jan 26 19:37:53 avion bluetoothd[900]: Unable to register GATT service with handle 0x000e for device C2:01:31:4D:2A:06:

  Jan 26 19:38:25 avion kernel: [  468.649120] Bluetooth: SMP security requested but not available

  Some days ago I managed to connect the mouse after several tries but I
  can't reproduce it. With the keyboard I wasn't successful at all.

  If there is anything I can do to solve this problem, let me know.

  Thanks and regards,
  lum3n
