Hi Cyril,

good to hear from you and your experience.

I myself unfortunately have never worked on the (much more complex) "smart"
Quectel modems (SCxx), just on the regular ECxx series.

It's indeed quite odd that they provide a "plain Linux" yocto based SDK
but then have no information whatsoever on how to talk to the modem ;)

Maybe the people behind https://github.com/bacnh85/Docker_Quectel_SC20_Linux
have an idea?

I would normally expect that there is either some way to access AT commands,
or to access QMI.  Once you reach either of the two, you can then use ofono,
modemmanager or the like.
