Right. Just "default" configuration. >Also, it's not that libqmi "goes faster"; it likely is that ModemManager does more steps than your single qmicli commands. >And of course, if using libqmi, you'll need to detect the disconnection and re-connect yourself (i.e. a single --wda-start-network won't reconnect). Yes...ModemManager handles it all with that funny DBUS thing.... I´ve added --debug info for it here. I´ll check your --wda-set-data-format=802-3 suggestion. <div>> > Also, wen using NetworkManager I see lots of CDMA trial an error probes. I´m > > not going to use CDMA.
