I have the 3DR I2C airspeed probe, it’s configured as such:
ARSPED_FBW_MAX 40 (m/s = 144kph)
ARSPED_FBW_MIN 9 (m/s = 32kph)
I get an airspeed of about 13 on my bench.
If I blow in the tube it goes up
if I blow on the static holes on the side of the tube, airspeed goes up too (that’s wrong, it should go down)
I tried changing ARSPD_TUBE_ORDER to 1 and then I get an airspeed of 0, but I get no speed if I blow in the tube. However if I blow a lot in the static port, then speed goes up.
If I change ARSPD_TUBE_ORDER to 0, I get the same airspeed than order of 2.
Any idea what’s wrong?
