I have Pi 4 with Base HAT plus Telit LE910C1 which I understand from Sixfab docs does support QMI. I’ve had difficulty getting satisfactory results with PPP (see my previous question - it kind of nearly works) but on reading the literature, maybe QMI will better meet my needs.
Looking to install QMI, do I need first to roll back the PPP installation in any way?
Following the instructions for installing QMI with libqmi, I find lsusb -t output:
pi@Cedd:~ $ lsusb -t

with no entry showing qmi-wwan or GobiNet. What should I do about this? I don’t want to proceed installing libqmi-utils until this is sorted out.
Thanks for any help
Thank you, Ensar. Following your suggestion:
