Recently had to re-install my Endeavour, and having issues getting the system to talk to my Bluetooth speakers. It sees them, but simply won’t connect to them telling me “br-connection-unknown”. I’m not able to determine the issue, I’ve tried switching from pulseaudio to pipewire no change.
Currently running Plasma as the DE.
Any assistance would be greatly appreciated!
Welcome to the forum!
Did you try sudo systemctl enable --now bluetooth
welcome at the forum 
Bluetooth is not enabled per default on EndeavourOS, so user can decide to start it only if needed to enable it to be active over reboots.
Hi Joe,
Yes I went through that article, and as I said my system can see the speaker, it just won’t connect to it.
This includes after rebooting.
the first thing to try is to use sudo bluetoothctl (CLI tool) to add device the first time)
power on
agent on
default-agent
scan on
trust deviceuuid
pair deviceuuid
connect deviceuuid
deviceuuid (replacing) of your speakers looks like so: 00:1D:43:6D:03:26
show also status of pipewire and Bluetooth:
systemctl --user status pipewire.socket
or inxi -A
and
systemctl status bluetooth
Here are the results I got back:
[chris@endeavour ~]$ sudo bluetoothctl
[sudo] password for chris:
Agent registered
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent is already registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on

never saw such…
but anyway you need to remove the device before using to re-add it from cli 
Thanks, this fixed it, still wish I knew why it refused to connect earlier.
are you dualbooting?
Yes
As to recognize the device BT uses keys… and if you are dualbooting and using the device in different OS the keys changes what is resulting in not being able to connect
