Question about the estimated heading in GPS mode

[gponcon]

So your original IMU was bad?

Probably. I use the same RPI as before, with the same settings. I have just crossed from France to England, everything went perfectly well.

What kind of error message did you see related to pypilot_hat?    What do you mean the executable doesnt produce any results?

The LCD display shows nothing.

Code:

$ pypilot_hat
hat start 81252.403403063
have gpio for raspberry pi
hat import done 81252.440801153
loading config file: /home/guillaume/.pypilot/hat.conf

Code:

jq . ~/.pypilot/hat.conf

}

I tried to change the value of "driver" without success.
