Turn off GNSS on RC7620

Does anybody help me to turn off GNSS functionality on RC7620? Which AT command can be used? I want to save the power consumption as I don’t use that. As far as I tested, the GNSS data is always sent to the USB interface.

have you tried to use AT!USBCOMP to disable the NMEA port in USB?
Also have you tried to use AT!GPSEND to stop the GPS function?

Does not help. The power is the same.

how about the followings:


Done already. Thanks

Then it is turned off???
