Fibcom FM350-GL not able connect to network with 5G mode

[Dirk Su]

Fibcom FM350-GL can support 5G network (https://www.fibocom.com/en/products/5G-FM350-GL.html). But in Ubuntu 22.04, system can only connect to mobile network with 4G mode.

Tested with Upstream ModemManager, libmbim and libqmi. The WWAN function can be turned on through gnome-control-center, and 5G function works correctly. The upstream version get with "git rev-parse --short HEAD" listed as below:
 ModemManager: eebdbc45
 libmbim: add668b
 libqmi: fa6c7a97

[Muralidharan (sethurmu)]

Hi Canonical team,

One of the OEM was requesting regarding the libqmi

> libqmi: fa6c7a97
Not like the commit ID you shared for MM and libmibm, the libqmi commit ID is not a version bump commit, can we use a911f6874493a0e6a567cecf4582584312cd8d23?
or the next version bump?

Please do share if you have any further inputs.

Thanks and Best Regards,
Murali

[Muralidharan (sethurmu)]

Hi All,

Please ignore my comment #5 as only ModemManager and libmbim commits are needed for FM350 integration.

Thanks and Best Regards,
Murali

Status changed to 'Confirmed' because the bug affects multiple users.

[Jay Chen (jay-ch)]

to SRU team
this is why & when we would need this modemmanager package soon

at least 2 of top 3 PC OEMs have introduced new RPL-based platforms + FM350-GL to launch with Jammy (22.04) in Q1 '23 and with the fore-runners we need conclude the "feature complete" image release by Nov-18, 2022, and final (production candidate) release by Dec-09, 2022

So the requested timelines for modemmanager updated package is SRU (for Jammy) by the end of Nov '22.

5G function enabled with ModemManager 1.20.0-1

How did you get the FCC Unlock to enable the modem?
