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.
