Hello, I am trying to disable the use of GPS and I always get strange NMEA characters in the response.
For example, if I only disable GALILEO, it works fine, but if I disable GPS, it always fails.
Could there be an issue with the firmware?

PQTMCFGCNST,W,1,1,1,1,1,0 → work
PQTMCFGCNST,W,1,1,0,1,1,0 → work
PQTMCFGCNST,W,0,1,1,1,1,0 → not work never

Thank you. I don’t understand why I can select only BeiDou but not only Galileo. If I want to prioritize Galileo, how can I do it? I understand that GPS has an established error for non-military tasks, while Galileo, for civilian use, has an error of one meter, or even less with RTK.

If I am not mistaken, Selective Availability (SA) degradation was turned off on GPS satellites in 2000.

Yes, your information is very correct.
