It's good that people are interested! With the RCX couldn't you just have a robot broadcast a message to anything that could see the IR signal and was waiting for specific messages to arrive? Can a similar thing be done with BT? Would we be better (...) (18 years ago, 11-Aug-06, to lugnet.robotics.nxt, FTX)
