[Bug 1557298] Re: [Xenial][Bluez5] Low Energy Keyboard is paired incorrectly
Tested with the ThinkPad X230 BT 4.0 module and the result is that I can
pair and use the mouse however it fails to pair/connect the keyboard.

[Xenial][Bluez5] Low Energy Keyboard is paired incorrectly
Status in Unity Control Center:
Status in bluez package in Ubuntu:
Failed to pair low energy(bluetooth smart, 4.0) keyboard correctly.
Bluetooth smart keyboard is unable to use after bluetooth-wizard says
"OK". Also the passcode input is also not acting interactively like
when pairing with bluetooth 3.0(LegacyPairing) keyboard.
Above scenario also being verified with bluetoothctl and blueman.
Step to reproduce:
1. open Bluetooth Settings
2. click on Add New Device button
3. select the bluetooth le keyboard
4. input the passcode display on GUI
After bluetooth-wizard telling user is okay the keyboard should work
Pairing mode stop on keyboard, but still not work.
More details about versions:
xenial daily (20160307)
bluetooth controller 0cf3:e005 Atheros Communications, Inc. (hci version: 4.1)
Designer Mouse, bluetooth smart (pairable, work, re-pair work)
Designer Keyboard, bluetooth smart (paired, not working)
BT3.0 keyboard, bluetooth classic (pair and work)
BT3.0 mouse, bluetooth classic (pair and work)
In control environment with the same hardware system and devices:
trusty 14.04.1 + dist-upgrade (stay with 3.13 kernel)
bluez5 5.35 (ppa: https://launchpad.net/~vidplace7/+archive/ubuntu/bluez5)
It works with all above devices but can only be pairing through
bluetoothctl manually, since the older bluetooth-wizard does not
understand bluez 5.x.
Everything seems works fine, although there are a lot more error
messages, but since this bug is more about xenial, please let me know
if we need more information about this, I'm able to reproduce this
trusty scenario in anytime.
A little clarification, since I'm not sure how far the Bluetooth SIG is going to use Bluetooth Smart(Low Energy, or even Smart-Ready) to cover the versioning, I decided to just use what ever I saw on the product box.
