Has anyone tried to wire-OR the TX pins on multiple Arduinos? I've got a system that has 12 temperature sensing processors that send 40 measurements to a central unit. Total transmission time over 5 minutes is less than 0.5 seconds at 9600 baud, so collisions can be detected and resent. From the At…
