Quick note using BLHeliSuite32 motor test option did not seem to work yesterday. I was able to change directions of motors.
It has never worked for me
I have had results using it in the past. I did notice not long ago that only 4 motors motor tested on a Hex. I am build behind on the BLHeliSuite32.
I’ve found the motor test in particular is “more sensitive” to working or not working than the ordinary BLHELI settings.
I’ve started using an Arduino nano for initial config and testing rather than relying on passthrough - see the “Make Interfaces” page in BLHeliSuite32
