WRT comment #46: Installing brcm/BCM20702A1-0b05-180a.hcd from winterheart had no effect on this or any other Bluetooth anomalies I've observed except eliminating the "Direct firmware load" error.
WRT comment #51: in my environment this co-occurs with Bluetooth functioning "correctly", i.e. the only issue I see is this error message. (However, I am only using LE, not audio/BR/EDR.) I suspect it may be related to mixing HCI-based and D-Bus-based bluetooth control within or across applications, or to an application not properly stopping discovery before it shuts down. Or both. Issuing a "power off" "power on" sequence from bluetoothctl stops the error message. Getting from "unhealthy Bluetooth" to "working Bluetooth" may involve a power cycle, fixing multiple problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748565 Title: Kernel regularly logs: Bluetooth: hci0: last event is not cmd complete (0x0f) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1748565/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
