We have been trying for a couple of month now to operate the optical flow in the Aero drone.
According to the following link, you write that the Garmin Lidar 3 is not a good option:
Could you please point us to the latest checked (and working) firmware and hardware needed to operate the optical flow in the Aero (PX4 firmware version, Lidar type, etc ... ) ?
Thank you, yoni.
Thank you for your interest in the Intel Aero drone.
We only tested with Garmin Lidar‑Lite V3 but you can try other sensors and let us know if it works.
