Connect your VESC (FOC mode & Hall), enable RT and watch the tachometer. It will change of course when the motor is moving, mut its value will also change when you do a Full Brake or Stop and turn the motor by hand.
Except when you turn on handbrake and turn the motor by hand. Now the tachometer does not change.
Would be good if it does, because then you know that the handbrake level is not high enough.
I tried to locate the bug in the source code but failed to find the appropriate line.
