I am trying to use flow in PX4 by injecting flow messages with ROS. I have other ROS publishers working fine and sending data that is ultimately finding its way to the flight controller over mavlink. Despite this, neither publisher for “optical_flow_rad” nor “ground_distance” are finding their way to the flight controller. I can look at them using the rqt graph and rostopic echo, but they just never leave ROS and show up in the mavlink inspector in QGC.
I’ve looked at examples using flow and tried to keep close to those but still no dice. I have to believe there is something in config I am missing but can’t find. Any help would be appreciated.
