It makes no difference if arduino is connected to bus with display or not. So far I have tried only with one arduno. I have two arduinos and available so I could add another to the bus and see what it sees an the bus. Would Actisense listener be the sketch to download to the other arduino? So far I only have tested hardware with one arduino with this test program:
