[Bug 1551858] Re: [bluetooth] Connecting to Apple BT keyboard fails due to PIN prompt

[Tony Espy]

** Description changed:

  Connecting to the latest generation Apple BT keyboard ( the one with the
  USB port & no batteries ) fails on an Ubuntu Touch device, as when you
  press the "Connect" button on the device page, a dialog titled
  "Bluetooth Pairing Request" is displayed, with the following text:
  
  Please confirm that the PIN displayed on 'Magic Keyboard' matches this
  one: XXXXXX
  
  The dialog has "Cancel" and "Confirm PIN" buttons.
  
  The keyboard has no display on which a PIN could be displayed.
  
  When using other devices ( Ubuntu Desktop 15.10, 16.04, Android, OS X,
  ... ) to connect this keyboard all that's necessary is to click/press
  the 'Connect' button in the appropriate place, and the keyboard
  automatically connects, and is usable with no other actions required
  from the user.
  
  Reproduced on krillin ( rc-proposed/bq-aquris.en/270 ) which has bluez
  5.36-0ubuntu2~overlay1 installed.
  
  Reproduced on arale ( rc-proposed/meizu.en/258 ) which has bluez 5.37
  installed from silo 39.
  
  Note, after dismissing the dialog, subsequent attempts to connect may
  not re-display the PIN dialog, instead nothing happens.  I've found that
  this requires power cycling the keyboard to clear and cause the PIN
  dialog to be displayed again.
