First there are many errors such as: "Not enough free handles to register service" in the syslog for the Bluetooth service.
Then the attributes of the BLE devices are not read due to the auth issue: "Error reading Report value: Attribute requires authentication before read/write" -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1557298 Title: [Xenial][Bluez5] Low Energy Keyboard is paired incorrectly Status in Unity Control Center: New Status in bluez package in Ubuntu: New Bug description: Failed to pair low energy(bluetooth smart, 4.0 or 4.1) devices correctly. 1. bluetooth smart mouse is being listed as "all type" in bluetooth- wizard, however it is able to be paired and use, even repair(i'm mentioning this because in some circumstance low energy device can be only paired once, bug #1515179) 2. 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 keyboard. Above scenario also being verified with bluetoothctl and blueman. - More details about versions: Environment: xenial daily (20160307) bluez 5.37-0ubuntu5 gnome-bluetooth 3.18.2-1ubuntu2 blueman 2.0.3-1ubuntu1 bluetooth controller 0cf3:e005 Atheros Communications, Inc. (hci version: 4.1) Tested devices: 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, 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. - Additional note: 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.
