I have been unable to get the Telit LE910C4-NF module working on an Odroid C4 running Ubuntu LTS 20.04 with the stock SixFab SIM. I’ve gone through the ECM route, and the QMI route on separate devices, but both yield the same inability to get connected. SIM card registered and active with funds inside the SixFab Connect portal.
The ECM route fails at establishing internet connection. AT#ECM=1,0 returns ERROR, as does AT#ECM=1,0,“”,“”,0
Sending AT+CMEE=2 yields OK, but the errors are no more verbose – they stay at ERROR.

In the QMI setup option (after setting AT#USBCFG=0):
I get lots of endpoint hangup/timeouts while completing the tutorial steps. E.g., --dms-get-operating-mode will return 5 Timeout/endpoint hangup responses before returning a successful
Operating mode retrieved:
Mode: ‘online’
HW restricted: ‘no’
I continue with the tutorial instructions, but never get a response from the command:
sudo qmicli -d /dev/cdc-wdm0 --wda-get-data-format
and the –wds-start-network command yields:
error: couldn’t start network: QMI protocol error (14): ‘CallFailed’
