Ah, right.  Do you have a distributable AT command reference for this
modem?  Is this a Telit specific firmware application, or do they use
"standard" Intel (Infineon) AT commands?

I do still wonder how to use the GPS on the EM7345.  FWIW, this is the
EM7345 output from AT+CLAC:

There are lots of promising commands there, like AT+XLGNMEA etc, but I
haven't figured out how to use them yet.

But this one is useful, reading the temperature sensor (in millidegrees
Celcius, obviously):

 bjorn at nemi:~$ mmcli -m 0 --command=AT+XTAMR=0
 response: '+XTAMR: 0, 48862'

Only thing is that I am pretty sure this should be available as an MBIM
command too.  And the fdc22af2-f441-4d46-af8d-259fcdde4635 service looks
like an obvious candidate. AFAICT, this is the "Intel ® Dynamic Platform
and Thermal Framework", ref https://01.org/dptf . This service supports
a single CID on the EM7345, 33554688, which takes some parameters I
cannot figure out. Using two 32bit integers like '01 00 00 00 00 00 00 00'
changes the returned error from INVALID_PARAMETERS (21) to
MEMORY_FAILURE (29)
