Advise on usage

[Lodewijk Duymaer van Twist]

Hello Aleksander, 

Thank you! And what would be the best way to do the missing features? I understand that MM only supports AT command's in debug mode. 

Kind regards, 

Lodewijk

I'd suggest using ModemManager, although some of the features you list 
may not be fully implemented using libqmi yet (e.g. Voice support is 
only supported via AT commands right now in MM). I would definitely 
just try MM on the device you're targeting to use, and then check 
which are the missing features, if any.

I used to blog about libqmi and ModemManager features in
