Hello: I am trying to set up a HGLRC PRO gps on a SpeedbeeWing F405 on SERIAL3 with little success.
I am not sure what else to disable, configure.

Even with the GPS green light pulsing … MP still shows "GPS 1: was not found. (This GPS works on other firmware / BF/iNav).

Did you set this? GPS_DRV_OPTIONS,4
If so try setting it back to default (0). It should probably work with all default parameters.

Yes - GPS_DRV_OPTIONS was set to 4. I have cleared it/rebooted… same results. Also, GPS status is alternating from No GPS to No Fix. I’ll try another GPS unit (perhaps without I2C/compass) and see if it makes a difference. Also, I set BAUD rate to 57600 - it is still showing this after a reboot.

Long shot here: Try GPS_TYPE,1 (auto)

Same result…

The battery voltage and “no GPS” message suggests you are running this off USB. Have you tried this with a battery and being outside with a clear sky view?

Yes, this was off USB. I’ll try outside, with a battery plugged in. Thanks.
