I would love to.  I have been trying to move to master for some time now but
on our platform there is a severe memory corruption in later versions that has been very
hard to track down.

One of the object initialisers is overwriting memory in the wrong part of an object and
causing MM to crash.  I did know where is was (and who) but I was pulled off it for
higher priority issues and it sbeen a while now :-(

Any thoughts on what could be causing glib object iitialisers to get out of sync would
be appreciated.  IIRC is was in and around the SIM creation and all in egenric code.
Doesn't seem to matter which Modem I am using it will crash.  Eventually I will be
free'd up to resolve this, hopefully sooner rather than later ;-)

As for the Telit, it would be nice if we could pull in some of the Telit plugins AT
command based methods to supplement the MBIM interface.  I couldn't see any example of
that but any advice on the best approach would be appreciated.

Cheers,
Davidm
