I have installed a TFmini range finder and have the output on Mission Planner.
It is out by a factor of about x 3.25, it reads 4m at 1.23m
As it’s data, I don’t see a way in MP to scale this. I would have expected there to be a multiplier somewhere.
Ardcopter FW V3.6.11
Mission Planner 1.3.70
Is working fine with the software (1.23m)
