    We are testing VOXL2 Collision avoidance with SDK 0.9.5.

    VOXL Vision PX4 is enabled and running and along with it are the below functionalities enabled,

    • VIO is renabled and running
    • Position hold is working and stable when testing the drone
    • DFS Server also enabled and running and voa_pc point cloud data can be visualised in VOXL Portal

    -> en_voa is set to true in voxl-vision-px4 config.

    Point cloud data is being published from voxl-dfs-server and can be seen in voxl-inspect-serices.

    • We have accurately specified extrinsics relation for body to stereo in extrinsics.conf
    • PX4 parmeters are set as per documentation,
    • Distances can be viewed in debug_stereo_linescan as well as in obstacle distances in QGC which are fairly accurate.

    dfs_disparity scale and voa_pc are both present in the VOXL portal.

    Stereo sensors are calibrated as reprojection errors are under 0.2 but collision prevention is not working during flight during Position hold mode/Altitude mode.

      Hi there, do you have COM_OBS_AVOID=1 (enabled)? You can set the parameter directly (params) or there's a menu option in QGC.

      If so, can you arm the drone? With *_AVOID=1 I suspect all will work as you are seeing obstacle_distance data on mavlink.
      If not, then you should get a QGC report "Avoidance system not ready"--let us know which case you end up with.

        @Cliff-Wong When I set COM_OBS_AVOID = 1 the system says it is not ready to fly, but I am not getting any messages as Avoidance System not ready
