Re: [PATCH] gnu: services: Add bluetooth-service.

[Alex Griffin]

Thanks for writing this, I've been wanting bluetooth support for a
while!

I added this to my system services and added my user to the "lp" group,
but I still ran into a few issues. GNOME still didn't recognize my
bluetooth adaptor, so I tried using bluetoothctl from the command line.
Several actions completed successfully but I still couldn't use my
bluetooth mouse. Here's what I tried (I omitted all output except the
error):

$ bluetoothctl
[bluetooth]# scan on
[bluetooth]# pair <addr>
[bluetooth]# trust <addr>
[bluetooth]# connect <addr>
Failed to connect: org.bluez.Error.Failed

I also couldn't find any bluez files in /var. Is it possible that it's
failing because it can't save its state?

I can look into it more this weekend if you can't reproduce any issues.

I haven't try it in GNOME yet.

Yep, I got this too for my headset + usb controller.
But now with bluez-enabled pulseaudio, it working :-)

Maybe, is there interesting things from /var/log/message?

Typo.

I guess it’s not “your fault” ;-), but why is it called “lp”?  That
makes me think of a printer.

Otherwise, if the issues Alex mentioned are fixed or under control, that
LGTM!

Thank you!
