This is interesting then; the modem does get online (as opposed to the
QMI modems, which fail to set the full-power mode), and it even gets
an IP assigned, but then no traffic flows through the interface?
The work I've been doing in the qmi-over-mbim branch from ModemManager
would not work if this is the case, as it assumed that for MBIM modems
the failure would be when getting online.
And if this is true, then what we need to do is unconditionally try to
send the FCC auth via QMI over MBIM for all these modems; maybe even
as a generic thing in the MBIM implementation, as likely other modems
from other vendors will just give an error when trying to use that
specific MBIM service.
What do you guys think, should we unconditionally try to send the FCC
auth via QMI over MBIM in the generic MBIM implementation? E.g. during
the power-up sequence.
