Bluetooth failed to setup

Hi.

I’ve been using HA for about a year now but in the last few months I’ve been getting an error with bluetooth. It’s been failing for months, but not really causing any issues. I’ve got some Flic buttons which just seem to work even with the error.

That changed recently and now none of my Flic buttons will respond. I’ve looked around but can’t seem to find any solution.

I’m using a Dell Optiplex with built-in Bluetooth on HAOS.

I even purchased an ASUS BT500, but I can’t seem to get this to work either.

I get this:

“Failed to start Bluetooth: [org.freedesktop.DBus.Error.UnknownObject] Method “SetDiscoveryFilter” with signature “a{sv}” on interface “org.bluez.Adapter1” doesn’t exist”

Unfortunately I’m not super technically gifted and so this doesn’t mean much to me, if I need to pull some kind log please let me know

I’ve got 4 flic’s around the place and I really like them, so I really dont want to have to replace them!

Thanks
