Ekf3 optical flow sensor problem ( in loiter mode )

@rmackay9,

I see, thanks for the clarification and help once again!

need help pleasee, anyone.
i’ve succes changing the flight mode to the loiter mode using cuav px4flow. but it didn’t goes well, my drone start drifting and can’t lock the position for hovering. i dont know what step i miss from calibration and setup phase. but i’m pretty sure my setup and calibration is enough. i’ve got the value of scalar X and scalar Y between -200 and 200. and my fit is already small, the value is 0.01.
i start the calibration in outdoor environment, but im testing the loiter mode in indoor flight.

You need to first follow all (you can skip some of them, if the tool explicitly tells you that the step is optional) the configuration and tuning steps presented in the:

After that drifts will be gone, if your px4flow sensor is working properly
