My Sphero Mini disconnects when I plug it in
Sphero Mini is engineered to reset when it is plugged into a power source, which means that when you plug Sphero Mini in to charge, it will drop any connection to the app. Not to worry! Once plugged in for a few seconds, you can reconnect with the robot without having to exit the application. However, this does mean that if you're playing a game and plug in your Mini, all progress will be lost.
Also note, Sphero Mini can't drive when plugged into a power source.
