Bdtyktl

I have a mid-2014 15" MacBook Pro running Ubuntu 18.10. I have successfully paired an Apple Wireless Keyboard A1255 (one of the previous generation before the Magic Keyboard). However, I have a problem with my favorite keyboard, an 1st-gen Apple Wireless Keyboard (model A1016, the white plastic one).

I've been looking all over and it seems like these keyboards are quite finicky, but some people have reported success. However, I have followed their steps and have been unable to do it.

This is what I'm doing (and which worked with the A1255):


$ bluetoothctl --agent KeyboardOnly
Agent registered
[tumbolia keyboard]# agent on
Agent is already registered
[tumbolia keyboard]# default-agent
Default agent request successful
[tumbolia keyboard]# scan on
Discovery started
... wait for the keyboard's MAC to appear
[CHG] Device 00:0A:95:48:C3:A2 LegacyPairing: yes
[CHG] Device 00:0A:95:48:C3:A2 RSSI: -40
[tumbolia keyboard]# pair 00:0A:95:48:C3:A2
Attempting to pair with 00:0A:95:48:C3:A2
... wait for a while
Failed to pair: org.bluez.Error.AuthenticationTimeout


However, if I hit Enter on the keyboard I'm trying to pair while bluetoothctl is attempting to pair, I get:


[agent] PIN code: 691484


If I enter that PIN followed by Enter, I get another different PIN, and so on until it times out.

From this it would look like the agent is displaying the PIN code after it has been entered, instead of before (which of course makes it impossible to pair, since I don't know the PIN I have to enter before I enter it).

When I paired the aluminum keyboard (the A1255) it worked correctly, I got the PIN prompt before entering it.

Any ideas?
