Have latest release Rover firmware installed on a Pixhawk 2 and HERE GPS.
Changes to the GNSS parameters don't seem to propagate through to the GPS:
GPS_GNSS_MODE - changing this has no effect
I configured it for GPS+GLONASS+QZSS+SBAS in uCentre.
Reconnected to MP. Set "MODE" to 1 - GPS - no SBAS.
Connected to uCentre.
Still configured for all the constellations.
Any ideas what I'm doing wrong?
