When I use bluetooth, it can not connect any device. Here is the error:
❯ bluetoothctl

Bluetooth support became a mess after the last updates. I have some controllers and some adapters. I have no idea what is happening. Sometimes they work and connect without issues, sometimes don't. Maybe some kernel driver related? I don't know

Had the same error (with headphones).
It's seems like it's caused because something's missing in system: https://github.com/bluez/bluez/blob/bb1 … xt#L26-L30
I've installed `pulseaudio-bluetooth` and now it works. Btw, it's an optional dependency of `bluedevil`.

I have the same issue.
Installing pulseaudio-bluetooth did not change anything, neither did setting "ControllerMode = bredr" in /etc/bluetooth/main.conf.

Thanks for your replies, I will try them tonight. (*^_^*)

Yes. The methods do not work for my bluetooth too.
It is strange that the bluetooth would connect my device for about two second when I try to pair them, then it will disconnect and repeat the previous error.
This error appeared since the last bluez update. I tried to test it on another PC and the same error appeared.

hi, after seeing exactly the same behaviour I just wanted to add my observations to this thread; i was able to reconnect with my headphones after doing a full reboot and then in bluetoothctl a trust <dev>; (before the update, the device was trusted of course); afterwards, i could connect without issues;

What type of devices have you exactly tried to connect, headphones/speaker, or something else? Did you reboot after installing pulseaudio-bluetooth?

Hi. I have another PC (openSUSE leap), a mobilephone and two headphones. All of them can not connect to my Arch and they can connect to each other (Obviously the two headphones cannot be connected to each other).
The same error appeared after I installed arch on another computer. They worked well two weeks ago on arch.
Oh, it is my mistake. Yesterday I just restarted bluetooth.service with not reboot. The Bluetooth works now after I installed pulseaudio-bluetooth and fully rebooted Arch. Thanks very much! The problem has been solved.

Works here too when rebooting after pulseaudio-bluetooth was installed.

There have been some weird problems with bluetooth for the last few days.
My bluetooth sometimes crash and I have to reboot the service. Something in systemd about "dbus message" not working or stuff.
If anyone have a solution... it doesn't happen very regularly but it's annoying. Hope it gets fixed by our volunteers soon.\

Problem persists for me.

Had pulseaudio-modules-bt installed.
Changed it for pulseaudio-bluetooth and my headphones worked after a restart.

I am also experiencing this issue using pipewire after upgrading bluez, bluez-libs, and bluez-utils all from 5.61-1 to 5.62-1 today. I already had pulseaudio-bluetooth installed.

For me the problem initially happened intermittently after restarting the service and rebooting.
Once I noticed in
systemctl status bluetooththat the A2DP modules seemed to be getting loaded with a long delay.
When initially trying to connect to my headphones,
src/service.c:btd_service_connect() a2dp-sink profile connect failed for [MAC]: Protocol not availablewas logged, but almost four minutes later it spontaneously connected, along with the following from the logs:

I did a fresh installation yesterday. Today I installed bluez, bluez-utils (not yet pulseaudio-bluetooth), and started bluetooth.service.
$ pacman -Ss bluez | grep installed
extra/bluez 5.62-1 [installed]
extra/bluez-libs 5.62-1 [installed]
extra/bluez-utils 5.62-1 [installed]Then I ran bluetoothctl, and was able to power on the controller, scan, find my headphones, pair with them and trust them.
After trusting them, i tried to connect, and bluetoothctl returned the error reported in the initial post: "br-connection-profile-unavailable".
So I found this post, installed pulseaudio-bluetooth, rebooted.
Now bluetoothctl says there is no default controller:
# bluetoothctl
Agent registered
[bluetooth]# power on
No default controller availablerfkill says that no device is blocked
# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: noI tried stopping bluetooth.service and starting it in debug mode (and it still says in one of the last lines "Number of controllers: 0")

Getting "br-connection-profile-unavailable" and "br-connection-unknown" intermittently on bluez 5.62 + pipewire 0.3.39 packages (only pipewire-media-session is 1:0.4.0 after routine pacman -Syu with default repos).

In this case, should I delete the ‘resolved’ in the title or re-report the issue? I don't know.
I did a fresh installation yesterday. Today I installed bluez, bluez-utils (not yet pulseaudio-bluetooth), and started bluetooth.service.

I have the same issue.
Installing pulseaudio-bluetooth did not change anything, neither did setting "ControllerMode = bredr" in /etc/bluetooth/main.conf.
Thank you, solved my problem.

For anyone else, I was having similar issues until I recompiled the btusb module.
The problem was the 'alt' mode of the adapter.
Here is the btusb.c code - btusb_work
* Bluetooth USB spec recommends alt 6 (63 bytes), but
* many adapters do not support it. Alt 1 appears to
* work for all adapters that do not have alt 6, and
* which work with WBS at all. Some devices prefer
* alt 3 (HCI payload >= 60 Bytes let air packet
* data satisfy 60 bytes), requiring
* MTU >= 3 (packets) * 25 (size) - 3 (headers) = 72
* see also Core spec 5, vol 4, B 2.1.1 & Table 2.1.
*/
if (btusb_find_altsetting(data, 6))
new_alts = 6;
else if (btusb_find_altsetting(data, 3) &&
hdev->sco_mtu >= 72 &&
test_bit(BTUSB_USE_ALT3_FOR_WBS, &data->flags))
new_alts = 1; /* MY EDIT - WAS 3 */
else
new_alts = 1;
Changing the alt to 1 (it was 3) sorted all my issues

Was working for a while, now fails again (br-connection-profile-unavailable) on bluez 5.62/kernel 5.15.1. Downgrading to 5.14.14 does not help.
