I’m trying to use a Firstnet SIM with Sixfab base HAT and Telit LE910/C4 module. Using this tutorial to setup QMI:

I’m getting two errors:

root@ubuntu:/sys/class/net# sudo qmicli -d /dev/cdc-wdm0 --wda-get-data-format

error: couldn’t create QmiDevice: Couldn’t query file info: Error when getting information for file “/dev/cdc-wdm0”: No such file or directory

root@ubuntu:/sys/class/net# sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net=‘net-raw-ip|net-no-qos-header’ --wds-start-network=“apn=‘broadband’,ip-type=4” --client-no-release-cid

error: couldn’t create QmiDevice: Couldn’t query file info: Error when getting information for file “/dev/cdc-wdm0”: No such file or directory

I’m confident that the apn is correct because I have used this SIM card before. Any help would be great.
