KDE Network Manager doesn't allow editing of a Bluetooth dun connection

gumb
Leap 15.1

The other day I had the need to connect to the Internet via my mobile,
so having torn my hair out for a good twenty minutes trying and failing
to create a mobile broadband connection via USB, I changed tack and
looked in the Bluetooth settings. There I was able to configure a dun
connection by selecting my country/operator, and it worked.

However, now on every boot/resume it tries to autoconnect to this
bluetooth network. I reviewed the settings in KDE Network Connections,
changed the priority to -1, unchecked 'Automatically connect to this
network when it is available', but it's not possible to save these
settings, neither with the Apply, OK buttons nor by selecting another
network and hoping to be prompted, as happens on any other connection I
change. The Apply button remains greyed out no matter what changes I
make to the bluetooth connection.

My only choice hence is to completely delete the connection and to have
to recreate it every time I might need it, because on my free mobile
contract I only get 50mb of data per month, the rest is charged
out-of-contract. I can't risk being unknowingly connected and running up
a huge bill!

I assume this is a bug but should it go upstream? Can anybody reproduce it?

Yes I can reproduce it one on one.
I created a DUN connection with my 3G umts BT phone and as a result, although
the setting is -1 or even -100 (does not matter) the priority is disregarded.
It always stays on "0". Also firewallsettings are not taken over. I have thus
a double connection for this device. DUN and NAP and I use at the end the BT
NAP settings.
All this happens also when you are on a wlan or ethernet.
I have "secure" settings, so the only annoyance I face is that I am asked the
root password to change networksettings (which I -obviously- deny). BTW try
that out: it does not matter if your phone is switched on or in reach or not.
It just tries to connect "wildly" just like that.
Unfortunately I have bad news for you. If I am not wrong DUN will be taken off
as capacity from BT if I am not wrong. You better check if this is true, I
read something about it, but did not pay excessive attention.

But I can confirm the bug for KDE (stock) in 15.1 openSUSE.
If you open a bug I will cc and even vote for it.

Tipp: check for your priority after a reboot. If I am not wrong your priority
is again at 0 for DUN when you reboot.

Thanks for checking. Potentially a shame if dun support is removed from
bluetooth, although it's not something I use regularly. By the time it's
gone I might well have another phone / solution.

Likewise, on my system it continually tries to connect every few
minutes, indeed it is doing so right now as I type despite the fact that
I have another active, stable wifi connection. Which seems to indicate
that the edits I just made to the file in
/etc/NetworkManager/system-connections/ have not had the desired effect.
Unless I need to run a command for this file to be re-read.

I added the following lines in the [connection] section:
autoconnect=false
autoconnect-priority=-1
zone=external

copying from what I see in files for other connections.

I'll file a bug when I have time and let you know the link. I recall
once upon a time that for pretty much all KDE-related bugs it was
advised to post them upstream on the KDE bug tracker, not openSUSE
Bugzilla. I don't know if that's still the case.

Well for this one I highly advise KDE. It would be different if this would be
a case of bug fixed upstream, in this case you would have to file it to
opensuse (but to be honest with low hopes of getting a fix).

If you have e.g. a Nokia 4g 8110 banana phone, that one does work flawlessly
in wlan tethering and gives good results. BT dun is now really rare these days
(I guess because the f(x) has become really cheap when wlan is present as AP
on Smart and less smart phones.

Thanks for letting me know the bug number in case.

I've filed a bug here:
https://bugs.kde.org/show_bug.cgi?id=411562

I also found that after a reboot, the changes I made in that file in
/etc/NetworkManager/system-connections/ have thankfully taken effect,
and show up in the Network Connections dialog.

Oh, thank you.
I will then have some workaround for my DUN connect. Great.

And thank you also for the feedback.
