RVR + Arduino UNO

Hi, Sphero Support suggested that I repost this here:

“A very basic question here - I’ve loaded the “drive_raw_motors” example from the Sphero Arduino SDK onto an Arduino Uno board, connected the board to the RVR via USB, powered on the RVR, and… nothing happens… (the RVR firmware is up to date, as of 20.12.2019, by the way).
What am I missing here? Is the program on the Arduino supposed to execute as soon as the RVR is turned on, or does it need to be started somehow, or what is actually the expected behavior?. Is the drive_raw_motors example a complete code, or do I need to add some other commands to it, in order for it to elicit a response from the RVR? Thanks!”

Hope I can be of some help here. The lesson I learned from this thread is make sure you are using a short USB cable. The shorter the better.

I can now also confirm that it works with a short USB cable. In my case, 20cm.
