Issues Connecting to Telit LE910 through ModemManager, but not qmicli

[Aleksander Morgado]

>  I am working on creating a mobile embedded linux device using an LE910 module. I have been successful in using it to connect to the internet using qmicli tools, however, I'd like to have more sophisticated network management using ModemManager and NetworkManager. Unfortunately, I'm having some trouble connecting with ModemManager. I issue the command:

It seems very much like a bug in either ModemManager or the modem firmware, if I'm able to connect using just qmicli. Registering the network manually using "mmcli -m 0 --3gpp-register-in-operator=311480" also doesn't work. "qmicli -d /dev/cdc-wdm0 --nas-get-serving-system" indicates that the modem is registered.

Are you able to get a full ModemManager debug log?
