When I have my Flow unit connected, and connect the Pixhawk through USB, I can go to the “analyze” tab of QGC and it will show me various Mavlink data, including about 8 labeled Optical_flow_XXXXX. When I go to the same screen through telemetry, those are missing.
Since USB has much greater bandwidth than wireless telemetry, it supports (by default) more topics.
Is there any way to choose what topics go through telemetry?
I think you’d have to change the code.
