Computer-robot connection


My daughter and I built the starter kit and have done some basic programming via scratch. Other than the USB cable how does one connect to a Mac for uploading a program to the robot? I can’t get a bluetooth connection to work and even if I had the bluetooth connection the robot would need to be “on” and would be executing the program I had uploaded because there does not appear to be anyway to send a “Halt” command.
Thanks for any advice.


The programs can only be upload over the USB cable. The wireless connection by Bluetooth or Wifi is for remote control.
