If so, here are the parts of the official controller that it uses:
I indicated in green the joystick that is “R Shoulder Stick” from your first post. Because this joystick is not used for this particular model, I think that could be why changing the value has no effect.
From what I can see, only the two front joysticks and top button are used in this project - if you try to edit the servo settings in these two joystick sections, are you able to change their direction?
Thank you for all the extra detail and help. No, actually the design I had built was the Simple Remote for Cyberbrick with a modification for a 2 way stick addition.
But I believe I figured out what happened. When I finished constructing both the transmitter and remote, I followed the core load procedure using the phone app. I selected the Official remote and they Cyber Brick garbage truck. It loaded both, and then I was able to control the truck. But the transmitter stick (the new 2way) was causing the lift fork to move in the opposite direction. So I loaded the desktop app.
At the bottom of the app screen, after I connected both boards, it showed the “official remote”.
that is what I was trying to edit.
I went back to the simple remote listing, downloaded the JSON there, loaded it instead. This resulted in two configurations now showing:
I decided to try and edit this new one. Now all the drop downs are populated and I can change (the ones that were blank) and I can change and upload the value for the 2 way stick. So this resolved it.
