Just FYI: This is now done!
Moving a bit back and forth, it ended up inside uqmi instead of umbim.
That way we get MBIM support for *all* QMI requests implemented by uqmi,
similarily to what we have in libqmi+libmbim.
$ uqmi --help 2>&1|egrep 'mbim|fcc'
--device-is-mbim, -m NAME is an MBIM device with EXT_QMUX support
--fcc-auth: Set FCC authentication
This is tested and working with my FCC Auth enabled EM7455.
Using it can be a bit awkward, since you have to use umbim to open the
MBIM session, then uqmi to send the MBIM wrapped QMI request, and then
umbim again to close the session. But this is pretty much the way
uqmi/umbim are designed: They are just basic building blocks. You need
to build something on top using scripts or whatever.
Patches are here:
Don't know if this will be accepted, but I like it myself at least :)
(No, I'm not recommending uqmi on PC systems. Use ModemManager if you
can. uqmi is only for those who cannot)
