ModemManager 1.18-rc1 was just released this week, and the final 1.18

Hey Dan & all,
The send-delay property allows us to send the characters in an AT

It wouldn't be much to enforce internally using profiles when
connecting using QMI, if that's the way forward.

Nice! Thanks for fixing that.
I've also updated your MR in gitlab with an additional fix to handle
the proper WDS client allocation in the different muxed bearers; which
was a huge oversight... I'll have to start test

I still had to push an additional fix on top of yours to fix the
