Hello everybody, One of my RCX units is far less sesitive to recieve a IR signal from another RCX than the other ones. Can this be adjusted in some way? Thanks, Eric. (19 years ago, 16-Jul-06, to lugnet.robotics)

Has a SDK describing the structure of the NXT bytes codes been released, or has there been any mention from Lego as to when it will be released. I assume that the MDP have seen something, is it released or still under NDA? Chris (19 years ago, 11-Jul-06, to lugnet.robotics)
