I'm having trouble with the Commander app for Android. I've put an EV3 into set 8448. I'm using one of the large motors for propulsion and a medium motor for rack and pinion steering. I don't have the remote (using the education set) so I'm trying to use my phone as a remote instead. I downloaded the Commander app.
I went into "create my own". I can use a slider to make the car go backwards and forwards, however, I tried to set up two buttons for steering, one button to make the medium motor go one way and another button to make it go the other way. Only one of the buttons works. It's only possible to make the medium motor go one way, not the other. How can I make it so the button controls can control the motor in either direction?
Any help would be greatly appreciated.
