I did everything from Official guide
I went through every Optical flow topic in this forum topic. Cant make it work.
I can’t get rid of “PreArm: Need Position Estimate”
Also it seems that it does not get any data from sensor

P.S. EK3 Set origin position - does not help.

For those who experience same issue, please follow This guide from producent

After I went through this guide I was able to ARM in Loiter mode
