Details

I'm currently on GNOME, and sometimes when I go to the Bluetooth settings the
option to enable it is grayed out, so I can't connect to any of my peripherals.

'systemctl status bluetooth' tells me that the service is active.

'bt-device -l' gives me the following error:

ERROR:lib/bluez/adapter.c:165:adapter_get_dbus_object_path: assertion failed: (ADAPTER_IS(self))
Bail out! ERROR:lib/bluez/adapter.c:165:adapter_get_dbus_object_path: assertion failed: (ADAPTER_IS(self))
[1] 4742 abort (core dumped) bt-device -l

Reloading the 'btusb' module doesn't fix the issue. The only fix is to shutdown my computer,
unplug the power supply for a few seconds, and then boot.

I can confirm this issue.

In case it might be interesting for debugging purposes; My Bose headset makes voice announcements when it's connecting/connected/disconnected, and based on the voice announcements I receive in/from the headset, it briefly connects, and then immediately disconnects.

To add on, this also starts happening when I try to connect my headphones.
They make a noise indicating that they connected, and then Bluetooth immediately stops working.
I have to forget the device first before connecting to avoid this bug.

Similar here. After update few weeks ago, BT via Gnome stopped working - discovered devices are occasionally listed, but none can be connected (even if I try to remove and pair again). I can see bt-core dump in systemd journal as well, but not always.

Running `bt-device -c 04:21:44:40:97:64` produces: `Failed to start SDP discovery. Please make sure you have bluez-utils installed on your system.`
I have bluez-utils installed.

Running `bluetoothctl` and `connect 04:21:44:40:97:64` results in connection established and BT speaker works fine.

Is this bluez or kernel related?
Comment by Eric (harpium) - Wednesday, 09 February 2022, 04:50 GMT
I'm guessing it's a bluez issue since I switched to the LTS kernel for a bit and still had the issue.

Might be related. but I get this constantly repeating error in journalctl:

```

Then please check against bluez-git/check for known bugs/bisect/report bug upstream.

Looks like this was already reported in https://github.com/bluez/bluez/issues/272 and patched in response to: https://github.com/bluez/bluez/issues/284

bluez 5.63-2 should fix also this one here. please test.
Comment by Eric (harpium) - Saturday, 19 February 2022, 21:20 GMT
I've since switched to Manjaro, where this issue doesn't occur. If anyone else wants to test this, that would be great.

My problems with connecting to BT audio speakers in GNOME seem to be resolved now.

```
$ pacman -Qs bluez | grep local/
local/bluez 5.63-2
local/bluez-libs 5.63-2
local/bluez-tools 0.2.0-5
local/bluez-utils 5.63-2
```
