I am trying to program mBot as a line follower and I realized that when I coded and uploaded the code to mBot with the USB cable through my computer it works (almost) perfectly. However, if I use the “live” mode and Bluetooth to upload the code with the iPad (same code) it doesn’t work in the same way. It seems (from my ignorance) as if the signals arrive later or something to the mBot, it follows the line but it seems to be a delay so it doesn’t correct the path at the right time.
I tested at home with my computer and it worked, but in class with my students it didn’t work with live and bluetooth… a bit embarrasing!!
Hope I have made myself understood… Thanks a lot in advance.
