Hi guys, I hooked up my new Matek Optical Flow Sensor today. The lidar works, but I can’t activate the flow sensor. I can’t find the parameter “FLOW_TYPE”. I am using Helicopter 4.5
Thanks! Moses from Berlin

I found out during the night, the FC only has 1mb. It’s a f505 Matek. That does not work. Thanks!!
