Hi, I know that it's been almost a year but did you find a solution to this problem? Any help would be highly appreciated!

Best regards,

CK

So all you did was changing the ros_serial versions?

For anyone running into the same problem in the future:

Don't use the Arduino Moveo Software thats provided by BCN3D in the Repo that contains the STLs. There is another piece of Arduino software inside this Repo in the "moveo_moveit" folder -> THAT is the one that you have to run on your Arduino to make it work with ROS.

Kinda obvious but I seem to be not the only one that missed it at first.
