Love the new version 3.4.0 (for OSX) - it makes it much easier to load and unload extensions. But I can get the Demo extension to work only in the Arduino mode. I can’t get it to work in the wireless mode with the mBot (mCore). Can you provide an example of an extension that works for the mbot and works in the wireless mode (i.e. bluetooth or 2.4G serial)? That would be very helpful. efrank03
