@Eric-Katzfey thanks! I got started using mavsdk and pymavlink

@Eric-Katzfey said in Take-Off and Land command each fly to xy=[0,0] location instead of on the spot:

@LaborzaubererTHI Sounds like it may be similar to: https://forum.modalai.com/topic/2533/failsafe-landing-bug-in-px4-1-14/19?_=1713800679314

Indeed it does.

@tyorb It would be a massive undertaking and we would only be able to provide very minimal support. I'd definitely recommend against it.

@camharrisvayu Ok, we should be able to close this issue -- I flashed 1.0.0 and uploaded params for the sentinel model and that made it so the RC inputs could control the drone -- not sure which parameter made the difference, but I may investigate and report back if I find out.

@Nicolas-Ethan-Blanchard I also re-loaded PX4 parameters from the provided file in the GitLab, so that could have helped as well. Although, I do think that the IMU orientation parameter was set correctly initially, because it matched the parameter in the working drone.

Which version of PX4 are you running on the Pixhawk and do you have a magnetometer connected? EKF2 is generally unhappy about about starting without a magnetometer in PX4 1.11 so we patched the PX4 firmware for Flight Core to get around this. In PX4 1.12 and newer the following PX4 parameter can be set to allow EKF2 to allow position mode without a GPS/Mag

## disable mag SYS_HAS_MAG 0 EKF2_MAG_TYPE 5

Nevermind, apparently I looked in the wrong places:

https://dev.px4.io/master/en/ros/external_position_estimation.html has the answer: EKF2_HGT_MODE must be set to vision to use the voxl odometry instead of the barometer. Closing this.
