Offical Linux Support

[nlincke]

First: Nice Work!!!

I have not been successfull running this fix but anyway...

Has anyone news about the official driver support? Or the ModemManager Integration?

[enzingerm]

What exactly did not work for you with this solution?

I can't say anything about official driver support, but I am currently working on the ModemManager integration for this driver. It is done by writing a custom plugin for the ModemManager which takes care of the RPC communication which I have ported from Python to C. I just now was able to connect to the internet with the L850-GL modem and ModemManager/NetworkManager successfully for the first time (however, disconnecting/signal reporting/reasonable error handling is not yet built in). But it's still very hacky in many regards, as I had no experience with ModemManager before this.
However, I am planning to publish it in a ModemManager fork in the next days/weeks and maybe ask for help of other people in extending the functionality.

@enzingerm Where can we follow your work?

[nexus166]

@enzingerm please let us know! I'd also love to help out: can develop and test on a T495.

[enzingerm]

First of all, I'm glad that there are actually people interested in getting this to work 👍

I pushed my fork to https://github.com/enzingerm/ModemManager
It works for me with a T495 and the L850-GL modem (please note that I use a SIM with disabled PIN, I don't know if it works if you have a PIN set).
Almost all code is in src/plugins/xmm7360 (other than that, I only changed something in mm-filter.c to allow the exposed tty port of the modem and the Makefiles. As I said, even basic features as disconnecting a connected bearer is not yet implemented and there are for sure numerous bugs hidden. So try it on your own risk, just load the kernel module and start ModemManager. (ModemManager --debug) might be helpful.

Hi, Dell published this "https://dl.dell.com/FOLDER05569884M/1/L850_vV6.1.0.7_Linux.deb" tool to manage firmware of xmm7360 aka Fibocom L850 aka DW5820e, I assume it will be useful
for you. BTW I have dell 5401 and it's possible via BIOS to select default mode for the WWAN PCI/USB

@enzingerm how can we say "thanks" in dollars for you work? donate url will be awesome.

[enzingerm]

@tazhate Thank you very much for your offer. However, I don't feel like accepting donations for that project, as 1. it is still in a very pre-alpha state and 2. it is based heavily on the great work of @abrasive And as you might have seen, unfortunately there were no commits in the last few weeks. I still plan to further work on the ModemManager integration but there are other projects around which consume my time. A more important question for me is, did somebody actually get the ModemManager to work? I could provide further information on how to get the project running, if there is demand for that.

Actually I'm not quite sure what this package does. At first glance, it seems to provide some kind of a firmware update utility for Linux, but according to the udev rules it assumes the modem to be connected via USB.

Thank you so much for your effords to make this work. I'm using a T495, too. I'm on Pop!OS 19.10 and now I wonder, what I actually have to do. I took a look at your ModemManager fork but as far as I can see it is described, what it is. But not what I have to do to make it work.
I would love to have just a little small bit of advice on how to actually use it. Thank you so much in advance.

@RealTehreal I added a README with instructions with my latest commit at [0]. I am sure that it is not complete at the moment (for example I didn't remember all dependencies I installed to be able to build the ModemManager project). And just because it works on my system doesn't mean it will work flawlessly on yours. But I'd appreciate it if you share your experience when you tried it, maybe by creating an issue or so.

Hey, thanks for the response. Sorry for answering late, I'm quite busy right now.
I hopped over to your ModemManager fork and will continue there. Already got you an issue ;-)

I can confirm, this driver works on Lenovo X1 Yoga Gen3 (latest bios) with Fedora 32 latest kernel.

Please do not give up! It's a very nice work and very useful for a lot of people.

[wicadmin]

Yeah, please don't give up....hoping to see the xmm7560 supported too.

Hi! Were you able to send/receive SMS? Were you talking about the ModemManager plugin?

Hey, I don't believe anyone has managed to get SMS working via this device/driver combo.
