Wireless Sensing (Cont. User Comparison)
The RCX has simple IR number coding (0 - 255), while the NXT has bluetooth numbers (all), text (any kinds), and logic (variables, sensor data, etc.). Also, since the RCX uses it’s IR, it needs to be directly in front of it’s receiving RCX, while since the NXT uses bluetooth it’s receiving NXT can be within 10 meters of it in any direction. That’s about it for the wireless sensing.
