Hi team:

Following the procedure from “How to Run MAVROS on VOXL with PX4” we successfully get in to the process of testing mavros in off board flight mode.

When it runs, it show warning that:

[ WARN] [1162.141889870]: CMD: Unexpected command 520, result 0

[ INFO] [1164.120257369]: waiting for offboard mode

[ INFO] [1171.123370231]: HP: requesting home position

[ INFO] [1176.127489500]: WP: mission received

[ INFO] [1181.123081373]: HP: requesting home position 

How can we get position from the drone?

Hello, team Modal AI

When using your company’s product M500, I encountered the following problems. I hope you can help me with it. Thank you!

Before explaining the problem, I confirmed through voxl-vision-services that voxl-qvio-server is Enabled and Running. But when moving in to the next step, I encountered the following problems.

1. The voxl-qvio-client command cannot be used in guide m500 VIO.

2. The obtained T_imu_wrt_vio drone coordinates cannot be transmitted to the MAVLink inspector ODOMETRY.

3. Follow the website guide to PX4 Parameters (https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/tree/master), How do I identify what is causing the coordinates to fail to transmit and, when we find the problem causing it, where and what command should we put in, in order to change the setting?

Appreciate!
