Hi all,

As the title states, I have no odometry showing up in QGC, and I'm getting X/Y position error. My voxl-vision-hub and voxl-open-vins-server are all up and running, and I have tested with voxl-inspect-vins and voxl-portal to confirm that features are good and extrinsics are correctly configured. I have attached a copy of my Vision Hub and OpenVins server conf files. I also have all the default params for the indoor no-GPS drone configuration. Here you can see all of the params from this [log](https://logs.px4.io/plot_app?log=df3f7f49-e162-45fd-91b9-a5331817beae).

For reference, I am building a custom x8 quad using the VOXL 2 mini as my flight controller with no GPS or mag attached, as it is an indoor drone.

If anyone has any recommendations, please let me know. I've been stuck on this for a while.

@Samuel-Marchetti Perhaps this can help with the odometry? https://forum.modalai.com/topic/3341/odometry-message/3?_=1782862595827
