Well that didn't work. I backported f558fca8d64e3795b0654a90d343af1dd1d8b33c to xenial and found it only fixed "Failed to obtain handles for "Service Changed" characteristic" but not the errors immediately after it: "Not enough free handles to register service".
Sounds like that commit is not related to this bug. Also that commit didn't get released till Bluez 5.44 so it was solving a problem that existed in all Ubuntu releases (till artful got 5.45 last week). If this bug however was fixed in 16.10 or 17.04 then the fix must have been something different. -- 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/1490349 Title: 15:10 and 16.04: bluetoothd reports "Not enough free handles to register service" at start Status in bluez package in Ubuntu: Confirmed Bug description: On 15:10 after the bluetooth service has been stopped and restarted it is not possible to scan or connect to devices: $ sudo systemctl start bluetooth $ journalctl --unit=bluetooth | tail -n 19 | awk '{$1="";$2="";$4="";print $0}' 23:31:53 systemd[1]: Starting Bluetooth service... 23:31:53 bluetoothd[16647]: Bluetooth daemon 5.33 23:31:53 systemd[1]: Started Bluetooth service. 23:31:53 bluetoothd[16647]: Starting SDP server 23:31:53 bluetoothd[16647]: Bluetooth management interface 1.9 initialized 23:31:53 bluetoothd[16647]: Failed to obtain handles for "Service Changed" characteristic 23:31:53 bluetoothd[16647]: Not enough free handles to register service 23:31:53 bluetoothd[16647]: Error adding Link Loss service 23:31:53 bluetoothd[16647]: Not enough free handles to register service 23:31:53 bluetoothd[16647]: Not enough free handles to register service 23:31:53 bluetoothd[16647]: Not enough free handles to register service 23:31:53 bluetoothd[16647]: Current Time Service could not be registered 23:31:53 bluetoothd[16647]: gatt-time-server: Input/output error (5) 23:31:53 bluetoothd[16647]: Not enough free handles to register service 23:31:53 bluetoothd[16647]: Not enough free handles to register service 23:31:53 bluetoothd[16647]: Sap driver initialization failed. 23:31:53 bluetoothd[16647]: sap-server: Operation not permitted (1) 23:31:53 bluetoothd[16647]: Endpoint registered: sender=:1.440 path=/MediaEndpoint/A2DPSource 23:31:53 bluetoothd[16647]: Endpoint registered: sender=:1.440 path=/MediaEndpoint/A2DPSink And $ 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]# scan on Failed to start discovery: org.bluez.Error.NotReady To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1490349/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
