Hi, i’m using external visual odometry device to send the data as vision_position_estimate mavlink message. The copter ( v4.0.7 ) is able to receive those messages and i’m able to fly it properly. But i cannot view the vision_position_estimate in mission planner. Also using the call backs with dronekit, even then im unable to get the vision_position_estimate !! Is the any thing that i should checkout ?
