Hello,
I just joined the mailing list so can't directly reply to old messages,
so sending with same title.
I'm experiencing the same issue as Robert here
https://www.spinics.net/lists/linux-bluetooth/msg73824.html, happening
on the same laptop Dell XPS 13 but with different sub-model 9333, but on
openSUSE Tumbleweed.
It looks like the bluez component is in a wrong state when either
loading btusb with modprobe later on or resuming from suspend. The
workaround is to restart the systemd bluetooth daemon. I suspect that
plugging in USB bluetooth dongles would also have the same issue but I
don't have one to test.
It used to work correctly before the upgrade from 5.47 to 5.48.
See my original report here for details:
https://bugzilla.suse.com/show_bug.cgi?id=1076898
Robert's report https://bugzilla.redhat.com/show_bug.cgi?id=1534857,
also confirmed by a third person.
Please let us know if this is reproducible on your side or whether it's
an isolated case specific to our Dell hardware.
Thanks,
Vincent Petry

After resume from suspend, bluetoothctl sees the controller, yes and it
does report my usual three devices from the saved list.
When I tell it to connect to the headset (which is turned on), I can
hear the headset beep shortly which is the signal for connection, but
then it disconnects again:
Attempting to connect to E3:XX:XX:XX:XX:XX
[CHG] Device E3:XX:XX:XX:XX:XX Connected: yes
Failed to connect: org.bluez.Error.Failed
[CHG] Device E3:XX:XX:XX:XX:XX Connected: no
If I tell it to connect to my bluetooth watch it stays connected.
Now I wanted to try accessing characteristics but the command
"select-attribute" has gone missing ? I also tried "help gatt" as it
seems to be a submenu but it says "Too many argumnets". Possibly another
bug in bluez ? (I can send a separate email for this one if you want)
Anyway, I have a Python script that uses Dbus and said Python script is
able to connect to my watch and talk to it even in this state.
So the bluez 5.48 regression seems to be specifically with headsets and
also with scanning/discovering. I don't have any other device types to
test with.
The workaround is to restart the bluetooth service and enable bluetooth
afterwards.
Please make sure to look at
https://bugzilla.suse.com/show_bug.cgi?id=1076898 for logs I posted.
If you guys cannot reproduce the first regression I could try and bisect
bluez locally to find the breaking change. For this I need to know how
to set up bluez on my system after compiling. Is there any guide about
this ? Should I tell it to overwrite the existing libs and reboot or is
restarting the bluetooth service sufficient to make it use the newly
installed version ?
Thanks,
Vincent

Does the system have any controller after resume? Does bluetoothctl
report any device at all?

Hello Luiz,
I've applied the patch "[PATCH v2] core: Fixes order InterfaceAdded"
from https://marc.info/?l=linux-bluetooth&m=151801178209679&w=2.
Then tried suspend/resume a few times and can confirm that the headset
is now able to connect again !
I can confirm that the patch fixes the issue for me !
Is there a timeline for the next bluez release ? Just asking because if
it happens much later we might want to apply the patch directly on
distribution packages (once reviewed and merged).
Cheers and thanks for the great work !
Vincent

Hi, I am also affected by this since updating to bluez 5.48.
My distro is Arch Linux, pulseaudio 11.1-1, linux 4.14.15, using a
Bose QuietComfort 35 headset with an Asus zenbook laptop (Intel 7260
wireless chip).
Please let me know if I can be of any help.

Hi Luiz,
Can you give me some pointers where I should put the gdb breakpoint to
get a useful trace ?
I also saw that there is some DBG function logging things. How do I
enable this logging and from where can I get its output ? Useful would
probably to log some internal state with and without returning from suspend.
Regarding the breaking patch, it seems to be related to some advertising
API that used to be marked experimental and is now not experimental any
more in 5.48.
Does maybe pulseaudio use this API and had a fallback at the time said
API was disabled ? And now that it's enabled its code path changed and
maybe triggered a hidden bug ? Would need to look at the pulseaudio
bluetooth source code.
Or does the patch in question enabled advertising where no advertising
was done before ? Maybe it is advertising too early at a time where the
system hasn't fully resumed from suspend ?
My pulseaudio version: pulseaudio-11.1-2.1.x86_64
Would be good if the other affected users post their distro + pulseaudio
versions for cross-reference.
Cheers,
Vincent

Jan 20 15:50:47 vvortex.ttv pulseaudio[1964]: [pulseaudio]
bluez5-util.c: Information about device
/org/bluez/hci0/dev_E3_28_E9_20_58_08 is invalid
Jan 20 15:50:47 vvortex.ttv bluetoothd[3136]: Endpoint replied with an
error: org.bluez.Error.InvalidArguments
So this is really PulseAudio rejecting the connection, it probably
loose track of the objects when resuming or we did not send the
objects but in that case bluetoothctl would not be able to list them
as well.

Please try this:
1. git clone git://git.kernel.org/pub/scm/bluetooth/bluez.git
2. cd bluez
3. git show d6e9539e31c6bb5afd39ec6f09c518d232e6345d
This will show your the first bad commit / the patch that introduces the
issue.
For the syslog, see attachments to my original report here
https://bugzilla.suse.com/show_bug.cgi?id=1076898
Do you have more information about how I could get the HCI trace ?
Should I run bluetoothd through gdb and query the backtrace from the
point where the error message happens, if that's what you are asking for ?

Im not able to decipher this, what is the patch where the problem
first appeared? Also could you collect the HCI trace and syslog when
it happens?

Hello,
I have bisected bluez between 5.47 (good) and 5.48 (bad) to find the
breaking commit for the headset reconnect issue.
Here are the results:

For every step I ran the following script that compiles and install into
the system and then restarts the service, followed by modprobe btusb.
The order is important to simulate hotplug or a return from a suspended
system.
Steps:
1. Run compile script from
https://gist.github.com/PVince81/95d01439490355babd4c405d28a548dc
2. Enable bluetooth in Plasma 5 panel
3. Run bluetoothctl
4. Run "connect" command with headset's address
5. Wait for connect. If it connects, test changing the volume in Plasma
5 which will trigger a pop sound to confirm it works.
Looking at the commit in question I can't tell in what way it is related
to our headset issues. Maybe a bluez expert can help here ? :-)
Please let me know if I can help testing patches.
Cheers,
Vincent

I'm seeing this too. My headphones go through a connect/disconnect
cycle a few times and then quit. Unpairing and repairing does make it
work.
