HelloFor last year or so I have been using 2.9.1b branch for work im doing where the ardupilot serves more as a sensor board and safety pilot. I wrote some basic code to send the sensor data over…Continue

"I've used some ToF sensors that were very susceptible to that issue and I've talked to people who have used lidarlite and they said there were issues going from one surface type to another. Just curious if others have had similar issues."
