GPS Here3 isn't working after update from 4.1.7 to 4.2.1


I updated the Arduplane from 4.1.7 to 4.2.1, and GPS just stop working.

I back it to 4.1.7 and everything works well.

No param changes, already updated Here3 firmware.

Did anyone have the same issue?

we’d need a log to help, preferably a log with 4.1.7 working and one with 4.2.1 not working

Hi @tridge

The first one in 4.1.7 is a flight just before the update.

Thank you.

@IgorSoares from the ArduPilot point of view it looks fine and just hasn’t gotten GPS lock yet. I notice that you’ve updated the firmware on the Here3, it is now running 1.8 whereas it was running 1.5 before.
If it doesn’t get lock after a reasonable wait I think you’ll need to ask on the CubePilot forums

Got it.

Thank you @tridge.

Hi @tridge, Just an update.

I changed it to GPS_AUTO_CONFIG = 1, and now it is working.

In the mission planner, we have a description for GPS_AUTO_CONFIG = 0, 1 and 2, as shown:

I note that this parameter has just two options in the 4.1.7 complete parameters list. It was configured to GPS_AUTO_CONFIG = 2 and worked.

For 4.2.1, it was changed, but when I set GPS_AUTO_CONFIG = 2, it stopped working.

Thank you very much :slight_smile:
