Optical flow (Hereflow) ALT_SRC Drifting


We were building a coaxial x8 with hereflow sensor for indoor purpose.

We followed the steps to calibrate the sensor according to the documentation and a reference video made by you on YouTube.

When we toggle the alt source mode to optical flow, the drone starts to drift.

We are using benewake lidar as a range finder.

I have attached the logs of calibration and first flight.


Please help us to find where we have made a mistake.

Thank you
