That requires a TTY that would spit out the GPS data; in this mode MM only sends the start/stop commands, and what comes out the GPS TTY is undefined (at least by MM). So unless you know that one of the 6600's TTYs does GPS and in what format it does GPS, then no. Doesn't --location-get-gps-nmea work for you? That will spit out the latest NMEA traces MM gets from the modem, if it supports NMEA. I believe --location-status will tell you what methods MM supports with the modem. Also available via D-Bus of course. > Is modemmanager enabling GPS, or is it talking to libqmi to do that? > The code is quite confusing to me... Yes. When the modem is driven with QMI, then all the data comes from QMI. For other modems (like Huawei HiLink and Gobi 1000) the enabling commands are done via AT on the main command port and then one of the TTYs starts spewing out NMEA.
