Hello Pololu engineers.
I recently purchased 2 pairs of IR Beacons (#702), wired them and started testing… Unfortunately, when paired, the beacons keep lighting the red LED’s randomly. I tried using the “paired” units or units from different pairs with the same result. I also tried all combinations of 2 beacons, either in a small room (maybe stray reflections, or in a large room (>10ft distance to the next wall) while the units are a couple of feet apart.
For power supply I use LiFePO4 2s (6.8V). Would you have a simple PIC sample code which just creates 56kHz modulated square wave at, say, 1kHz? Would the individual beacons #701 perform differently?
Thank you for your help.
