I would be very surprised if this issue was due to changes in the kernel driver. Are you able to post those qmi_wwan driver changes somewhere to review? Or, could you ask the manufacturer to do so? > We didn't need to do this update when doing operations in LTE (which was > using MM 1.12.8) as everything was happy with the default drivers. > > We have a functioning gNB in our lab, which the modem will connect to > (verified by the gNB / 5GPC and the modem using AT Commands) but we can't > "share" this connectivity with the compute platform connected to the modem. > > Is there anything that you could maybe suggest to address this? MM git master has additional changes 5G related, but I believe everything should work as expected in MM 1.14 as long as you're using the modem in QMI mode. I would first validate that; i.e. what's the output of "mmcli -m 0"? And then, I would probably go on and either enable debug logging in MM (launching the daemon manually with --debug or otherwise running mmcli -G DEBUG to change the level on runtime"), and see what QMI messages are being transferred between the module and MM. You could also try running qmicli NAS operations like qmicli --nas-get-system-info and --nas-get-signal-info and such. Also, is this 5G NSA or 5G SA? There are some reports about 5G SA IIRC, e.g. https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/256 -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
