    Hi, PX4 does not currently support the smooth handling of transitions in/out of stable vision odometry data. We're been working on this with the PX4 team but generally right now PX4's ekf doesn't have any support for handling quality metrics/resets. For both this reason and the fact that the vision data accuracy decreases with distance, we don't really recommend running VIO outdoors. We have done flights outdoors with it, but it requires the right conditions and flying relatively low (and this still will not play nicely with GPS).

    The VOXL 2 Flight Deck exists just for this purpose. You can use that to build your own drone around VOXL 2 to meet your specifications

    I tried another way to implement this. Currently my flight core is disconnected to the VOXL. I use my laptop as the companion computer, and then I add a ESP Wifi module to Flight Core TELEM1, so my laptop will get the motion capture pose by using vrpn_client_ros, the mavros will transfer the motion capture pose to mavlink data and then send to flight core. In this case, my EKF2 will converge. The new issue is that the modalAI cannot hover at it's height on flight mode or hold mode, and the modalAI will drift. Also, the mavros terminal will show:"RTT too high for timesync: 78 ms". I am not sure if this is the reason that the modalAI will drifting in position mode. Any suggestion?

    Hi @Caleb-Rievley I've only seen channels 5/6 work. I myself am not versed much in the use of mixers etc, but I'm sure it's possible.
