mouse not found with bluez5 but was fine with bluez4

mouse not found with bluez5 but was fine with bluez4

[Brian J. Murrell]

[-- Attachment #1: Type: text/plain, Size: 547 bytes --]

So, in chasing an issue with mouse pairing in another thread I was asked
to upgrade to Fedora 20 to see if my mouse pairing issue was
reproducible on bluez5 given that bluez4 is pretty dead now.

But the same mouse that could be found and paired on bluez4 (Fedora 19)
is not even being found during the search on bluez5 (Fedora 20) on the
exact same hardware (same machine in fact).  Bluez5 did manage to see
and pair a headset though, just not this mouse.

What information/tests can I provide to help figure this out?

Cheers,
b.

For one thing, it'd be good to determine whether this is a GUI thing (I
assume you're using the GNOME UI?) or something in BlueZ. The way to do
that would be to use the bluetoothctl tool that's part of BlueZ 5. The
commands you'd give it would go something like:

	agent on
	power on
	scan on
	<wait for mouse to show up>
	scan off
	pair <mouse addr>	(optional if the mouse doesn't support pairing)
	connect <mouse addr>
	trust <mouse addr>

I'm not sure if I'm interpreting this right, but it seems the device is
in HID mode and not HCI (normal Bluetooth) mode? Have you tried running
the hid2hci tool (part of BlueZ)? Maybe that was somehow auto-run with
your previous installation?

Not yet.  It wasn't installed by default on F20.  When I did though,
things went much better:

So it looks like it's a gnome bluetooth-wizard problem.  I will raise

I don't really know.  It was F19.  And that means bluez4.  So I guess
this is going to be a transition issue/bug I need to raise on F20.

Cheers and thanks so much!

I don't see why it would be a problem in the wizard. You basically
didn't have a Bluetooth adapter before you installed bluez-hid2hci.

bluez-hid2hci was already an optional package in F19.

But of course I also tried the wizard after correcting that.  I most
certainly could understand that the wizard would not have worked before
running hid2hci and would only assert that the wizard is not working by
trying it after installing bluez-hid2hci.

So just to be clear, I have a mouse working, so the adapter is
definitely in a state where bluetooth-wizard should work (right?), yet
it is not finding the headset I have sitting here in pairing mode right
this minute.

bluetoothctl certainly sees it:

But since I didn't have it installed on F19, apparently needing it on
F20 is a new requirement of Bluez5.

But really, I don't want to argue about it.  I have my machine working
and have gained a bit of operational knowledge about Bluez5 that will
serve me well as I migrate machines to F20.  I have filed a ticket with
the Fedora project alerting them to the new requirement.  It's now up to
them to decide how important it is that their F20 users don't have the
same problem that I had.

Cheers and thanks much for the help!

Is the headset still in the list of paired devices though? If so, it
wouldn't show up in the list in the wizard.

If you see it in bluetoothctl without typing scan, that means that
either it was discovered less than 3 minutes ago, or that it's a known
device (so paired or trusted, paired in the case of headsets).

If you do:
info 00:0D:E6:68:B4:6F
in bluetoothctl, you should also see which services your headset uses.
Some of them aren't supported yet in Fedora (HandsFree for example)
because the support was removed in bluez itself.

I've just double-checked, and it's not installed by default in F19.
Maybe you installed it and don't remember, or upgraded from an earlier
version that had it installed but disabled by default (there used to be
a separate config file to enable it after installation).

There's plenty of SELinux warnings in there. Maybe you need to enable
permissive mode, and/or file bugs about those.

Never mind, confusing with another headset issue I'm working on :/

That makes sense.  I wonder if that was/is the case with the mouse then.

Right.  I never had it installed in F19.  But my dongle worked anyway,
pressumably without having to use hid2hci

No.  I still have my F19 system.  I checked and it's not installed.  So
clearly this needing it on F20 is something new with bluez5.

Interesting that I don't get that that SELinux troubleshooter icon
notifying me of any problems, and nothing new is in the SELinux Alert
Browser.
