Hey,

>
> I’m using almost the latest modemmanager from master (commit hash: 0a85254d1765db6e55770d36e24b1e6349e789f4). When starting network scan using mmcli, the availability field is always “unknown” whereas for qmicli the “Status” is reported with more details. Please advise if this is desired behaviour in mmcli output?

I recall this being a limitation of the "MBIM Query Visible Providers"
implementation in some modules, which is what ModemManager does when the modem is managed in MBIM mode. You can see qmicli providing better data because it's doing "QMI NAS Network Scan" over MBIM instead.
