[gnome-bluetooth] Asked for PIN during pairing of Bluetooth mouse

[Karol Babioch]

Hi,

I'm not entirely sure whether this is a problem with GNOME Bluetooth
itself, or whether there is something wrong further down in the
Bluetooth stack.

Basically it is about my Bluetooth mouse (Speedlink Saphyr Bluetooth). I
paired it some time ago through GNOME Bluetooth (half a year or
something like that) and it worked fine (e.g. reconnected) until now,
even with the latest  packages. However for some other reason I had to
delete the pairing and repeat the process of pairing.

Surprisingly I've realized that this isn't possible anymore using GNOME
Bluetooth. During the process of pairing (after the mouse is discovered
and I want to proceed), I'm asked whether the PIN displayed within GNOME
Bluetooth matches the one on the device. Obviously the mouse  itself by
no means can actually display anything, so this seems odd and  wasn't
the case back when I paired it initially.

Regardless of whether I decide to click on the button that says that
they match or the one that says that they doesn't, the process of
pairing fails.

The log file doesn't look too suspicious, it seems that there is no
reply received for whatever reason:

However I can connect the mouse to my computer by using hidd directly
(hidd --connect xx:xx:xx:xx:xx:xx), although this is not a long term
solution as it has to be repeated every single time it gets disconnected.

So now I'm wondering what is going on here and where to go with this
problem. Let me know what else you would like to have to narrow this down.

Thanks in advance!

Best regards,
Karol Babioch
