A mouse pairs correctly. From my research it seems as if the ChromeOS project developed patches to fix this and they are supposed to have been included in Bluez 5.4 (that statement dated April 2013) but I've not yet identified them. "The agent's implementation in bt_console/bluetoothctl upstream is incomplete, missing some functions like DisplayPincode." https://code.google.com/p/chromium/issues/detail?id=222661 Along with the loss of Headset profiles meaning VoIP applications can no longer use HSP/HFP profiles (requiring functionality yet to land in Ofono) this cripples the use of Bluetooth for much else than A2DP or mouse input. Attempting to pair with, for example, an Apple Wireless Keyboard that pairs and works correctly with 14.04 LTS, fails totally on 15.10. The mouse shown below is already paired, connected, and working. $ bluetoothctl [NEW] Controller 00:1F:3A:E0:0A:AF hephaestion.lan.iam.tj [default] [NEW] Device 00:0A:95:4B:BD:C2 Apple Wireless Keyboard [NEW] Device 00:07:61:3B:86:98 Bluetooth Travel Mouse [bluetooth]# agent on Agent registered [bluetooth]# default-agent Default agent request successful [bluetooth]# scan on Discovery started [CHG] Controller 00:1F:3A:E0:0A:AF Discovering: yes [CHG] Device 00:0A:95:4B:BD:C2 LegacyPairing: yes [CHG] Device 00:0A:95:4B:BD:C2 RSSI: -48 [bluetooth]# pair 00:0A:95:4B:BD:C2 Attempting to pair with 00:0A:95:4B:BD:C2 >>> at this point nothing is happening >>> so I press Enter on the keyboard and...
