Can't get Telit LN940 to connect
Config : ModemManager 1.11.next
Hi, I'm trying to get a LTE connection up with a Telit LN940A modem and I can't seem to get around it. The main problem is that I can't get any data through. I can manage to send sms' through MM-gui but my RX data channel is desperately 0.
One of the issues at this point is that everything seems to work fabulously; the only error I could actually find is the following
Mar 23 15:40:33 localhost ModemManager[6463]: <info> error: couldn't start network: QMI protocol error (14): 'CallFailed' Mar 23 15:40:33 localhost ModemManager[6463]: <info> call end reason (1): 'generic-unspecified' Mar 23 15:40:33 localhost ModemManager[6463]: <info> verbose call end reason (2,210): [internal] pdn-ipv6-call-disallowed Mar 23 15:40:33 localhost ModemManager[6463]: <info> Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected)
So I'm using QMI with my modem and things seem rather ok from what I can tell. But ultimately I can't get any packet through.

` Network manager also does not seem to raise any issues.
Can anyone point me to what I should look for?
Best,
