OV with External Autopilot
-
Hi! I'm trying to use
voxl-vision-hubto send voxl-open-vins position data to an external autopilot (ardupilot). I start by making sure the following services are running:- voxl-imu-server
- voxl-open-vins-server
- voxl-camera-server
- voxl-vision-hub
- voxl-mavlink-server
I can confirm that the voxl and external autopilot are connected because I see this on Mission Planner MAVLink Inspector:
and the debug output I see after running

Thanks in advance for any guidance that can help me sort this out!

@SKA I would review this page if you haven't already: https://docs.modalai.com/voxl2-external-flight-controller/

@tom Thanks! I referred to this page in order to set up what I have right now.
My voxl 2 mini is connected to the external autopilot using the one exposed UART. It seems to be connected fine, since I'm receiving the voxl heartbeat on the autopilot end, and I'm receiving autopilot mavlink messages on the voxl side.I wonder if there is anything I might be missing on the voxl-vision-hub side, or elsewhere.
Thanks for your help!
