Hey all.  Similar topic, but with an MC7750 card.

I'm running libqmi 1.8 with an MC7750 on OpenWRT.    Trying to get GPS
NMEA output from the MC7750.  I'm not sure how to use libqmi/qmicli to
talk to the GPS, so I've been using AT commands to enable GPS, and
confirm that NMEA output is enabled.  The GPS looks like it's working,
but the problem is I'm not able to see any NMEA output on what should be
the NMEA port,  /dev/ttyUSB1.

Any pointers on managing GPS with libqmi?

Thanks,
Alex
