USB connection not working


#1

Help. I have purchased 11 of these for class and I can’t get the USB to work. It says it is connnected but nothing happens when you press the green flag to activate the code.

Can you try to upgrade the firmware and restore the default program as described the guide pdf here: http://learn.makeblock.com/getting-started-programming-with-mblock/

Hi fionaf1976,

When you do program online test, you need upgrade firmware to clear the previous uploaded program first.
