I need to write software or use Bluetooth for kids in same room to play games back and forth in multi player environment "without" using the Internet or using cell service. SMS maybe used but would like any ideas on other alternatives for doing this. Basically, just need to send strings back and forth to other devices in game so kids can control characters and play against each other.
Need to develop on Symbian, JAVA, Blackberry, BREW, WM, Android.
Give me your ideas to accomplish the same using any technology!
