Unable to connect bluetooth speaker/mic | br-connection-profile-unavailable

Home Assistant OS
#1

Hello,

I have homeassistant installed on RPI4 and I am trying to use its bluetooth module to connect a bluetooth speaker/mic but I always get this error: Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable

I am able to find the device, pair the device, trust the device - I just cant connect to it. The bluetooth speaker works fine, since I can connect to it with my phone. So there has to be an issue with how homeassistant handles RPi4 bluetooth module?

I tried all I could find on the internet regarding this error but no luck. Has anyone else experinced this issue and maybe solved it?

Some info about my system (fresh new install from official tool):
|Verze|core-2022.7.7|
|Typ instalace|Home Assistant OS|
|Hostitelský operační systém|Home Assistant OS 8.4|
|Kanál aktualizací|stable|
|Verze Supervizora|supervisor-2022.07.0|

|Verze Dockeru|20.10.14|

No ideas anyone? I really dont know how to procees with this, seems like its just not possible to fix it.

#3

encountering this too with HAOS full install on RPIv4.
discussion in this post about it as well.

#4

I came across that discussion before but there is also no solution. It seems like there is no solution for the issue atm and maybe future versions of HAOS might have this fixed.

#5

I wonder if the new Bluetooth stack introduced recently for 2022.8 makes it easier to connect to a Bluetooth speaker? Has anyone tried?

#6

I tried the newest version of HAOS and the error is still the same.

#7

Just tried the todays release of HAOS, still same error.
Below I am sending info command (you can see the device is paired and trusted) and connect command afterwards, where it fails to connect.
