I get this error when I try to connect Bluetoothily to a speaker. It worked for a few days, then I built kernel 6.1.5 and it didn't; reverting to 6.1.4 didn't help, nor did upgrading to 6.1.6, so I treat that as a red herring.

A search turned up a wide variety of 'fixes' which work for some, none of which work for me (nor worked for everyone in the threads). I searched at bluetooth.com for an explanation of error messages, to no avail. Nobody explained what the error means.

Both hcitool and blueman-manager return this error. Suspecting it's a hardware error I will buy a new bluetooth adaptor.

I got a new Bluetooth adaptor. I have the same problem. I went through all the stuff others (but not all) have reported working elsewhere. I wish I knew what the error meant.

I got a new speaker, different manufacturer: same error. I got a friend to pair with it with his 'smart'phone - that seems to work.

is the error.

is the error in syslog.

module-bluetooth-discover works only if started 'later' (whatever that means)
I commented out in /etc/pulse/default.pa, started it from the command line grrrr... I know how much you-all have been waiting for this.

I took this tip from a thread that said that it had to be started after X had started- the first tip that worked for me. I discovered this wasn't true. I guessed that the problem was pulse starting before bluetooth, but it doesn't (at least not on my system). I'm fresh out of guesses.
