As long as you're using the qmi-proxy setup when calling qmicli (i.e.
using the "-p" option), and you're NOT modifying the state or
configuration of the modem, there is no risk.

Reading the temperature should definitely be fine.

ublox SARA does not connect

[ron]

Hi

Im running a ublox SARA modem in an embedded system on ubuntu.

It is connecting fine on ubuntu 20.04, but remains in "registered" state
when setup in ubuntu 22.04. 

It seems that NM doesn't run pppd for some reason, or is it MM issue?
