@Eric-Katzfey Thank you. Could you lead me to the part of the code that sends the odometry mavlink msg in voxl sdk? That would be very helpful.

@Eric-Katzfey Thanks for your reply. Can we have more details about the interface we could use to feed position estimate?

About using another state estimation source, we would like to replace the onboard qvio with some lidar based odometry for localization and position hold purpose. Say we can get lidar-based position estimate in ROS message, can we disable the onboard VIO and feed our position estimate to the onboard flight controller through MAVROS or something else?
Please advise!

Please help advise on this question, thanks

@tom Thanks. I will get one of that.

@tom I see thanks. How about this one: https://www.modalai.com/products/m0062-2?srsltid=AfmBOoq_b52cK1R5X-8pluAer7oqq-BJb2Y1E2yUVsF2lFkwMl7mAFo2
It already has a usb and ethernet port, which seems to be more ideal for my case. Can it be fitted to starling 2 max without causing other issues?

@tom Ah... So what is your recommendation in this case? We need both wifi and connection to a ethernet device.

@tom I see. which port on the voxl 2 should i connect this board to? I wonder if this port has been already occupied on the starling 2 max drone.

@tom Thanks for your reply. Following up with some more details: i believe you mean connecting to the usb-c connector at the side of the the voxl2 board?
If we want to use the lidar-based odometry to replace the onboard qvio, what should we do? Should we inject the estimation into PX4 using MAVROS?

Hi, can some support answer this question?
