Mode Limitation Not Respected
I have a few systems running mmcli 1.10.0 with qmicli 1.22.2 that aren't respecting limitations on the supported mode. I've configured the modem (Quectel UC20) using modem manager to only accept 2g: -- Modes| supported: allowed: 2g; preferred: none | allowed: 3g; preferred: none | allowed: 2g, 3g; preferred: 3g | allowed: 2g, 3g; preferred: 2g |current: allowed: 2g; preferred: none However our device is still connected using UMTS: |access tech: umts Can anyone offer me any advice on how to fully disable the use of 3G? Thanks very much, -JohnF ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
Re: Fibocom L850-GL / Intel XMM7360
There are carrier firmware packages for some, but not all, carriers
(some use a generic carrier firmware instead). I'm not sure how you
are expected to flash them without the closed-source firmware download
tool, though.

Syntax is correct, not sure why the QMI command fails like that though.
What device is this?

Re: Fibocom L850-GL / Intel XMM7360
Hi Eric,
I think this is a very helpful hint!
We already started contacting Fibocom. If we know that there is in general a
firmware available which forces the module
in USB mode this would be a discussion option.
How does this firmware behaves in terms of provider specific firmware versions?
Are there carrier specific firmware
available too or is there a generic firmware necessary only?
Thank you & best regards,
Dennis
