I thing the bluetooth range is 10m. I want to use the arduino for android that is what it is made for. But I have a unock Cyogenmod Samsung S, rooted, with Ice Cream Sandwich. It has accessory mode. I just need a sketch to have a button in the eclipse andoird app, and an arduino sketch to connect to phone. Then a "Hello World" by using a simple pin 13 blink.
I cannot get the demokit to work! ughhh
thanks for help guys.
