Using the version 2.3 software on a Gertbot with a RPi B+, after I switch from DCC mode to DC-brushed, the duty cycle always remains at 50% and cannot be changed using the PWM duty cycle command.
After power-cycling the board, the PWM command acts as intended again.
I assume the duty cycle remains under control of a DCC function.
Is this a known bug, and is there a workaround available? For example a reset command to the Gertbot board.
