Maybe the ambient light is too high ? in that case you can decrease visible light sensitivity as well as shielding detector from red LED light using this method : (URL) (only hope that this doesn't offend your "Lego purity" sense ;o) Philo (...) (22 years ago, 16-Jan-03, to lugnet.robotics.rcx)

I have tried to get proximity dectection via RCX emitting IR (SendMessage/NQC) and Light Sensor (mounted on top of the RCX's IR unit). But the raw values seemed to be the same with/without emitting IR. Average value was 725. Went up to 800 (black (...) (22 years ago, 16-Jan-03, to lugnet.robotics.rcx)

Will the RCX remote control conflict with the IR signals from the Spybotics controller?

The size of the firmware isn't going past the 0xcc00 boundary, is it? The firmware in the RCX only does a sum on the bytes up to 0xCBFF in the downloaded firmware, as far as I recall... Cheers, Ralph (22 years ago, 13-Dec-02, to lugnet.robotics.rcx)

A likely explanation for your downloading problem is the following. Standard Lego software uses 2400 baud data rate and a protocol that sends "double" bytes. The "double" byte is that each data byte is followed by its complement. Alternative (...) (22 years ago, 10-Dec-02, to lugnet.robotics.rcx)
