I’m setting up serial communication between 2 FEZ boards (using Com1 on the Panda, and Com3 on the Cobra). I’m having a bit of trouble in finding a way to make communications reliable, meaning, if FEZ A is down, FEZ B should know this and wait with sending data till FEZ A is back alive. (and the other way around too)
Any idea how I can accomplish this?
The data that is being send over is plain text.
I also suppose both boards need to share common ground?
