  • Jimbo, very helpful tutorial but for some reason my link only works in one direction. I am just trying to get one imp to talk to one Arduino. I have been successful at getting data to the arduino but no matter what I do I cannot get the Arduino to send data to imp. I have tried with an Uno with softrware serial (as you describe) as well as on a Leonardo with the hardware serial. I get the same result, inbound communication only. Any idea why this might be happening?

    I am not using the shield but the Imp April dev board, could this have something to do with it? Am I supposed to be using level shifters with the April?
