as it did not help to have the antenna outside with a direct view to the
sky I again thought about what could be wrong with my setup. Asking
myself how to get the number of satellites the module sees I ended up
at libqmi and hopefully tried to do the right thing here:
root@MP:~ qmicli --device=/dev/cdc-wdm0 --loc-get-gnss-sv-info
[01 Feb 2018, 02:24:11] -Warning ** [/dev/cdc-wdm0] requested auto mode but
no MBIM QMUX support available
error: couldn't create client for the 'loc' service: CID allocation failed
in the CTL client: Transaction timed out
Could this be the root of my problems: not having configured libqmi with
QMI over MBIM QMUX service? (Although I thought I did it correctly - but
perhaps there is a quirk in my build system here that I would like to
debug if you give me a positive answer).
Best regards
Ulrich
