UNO/MakerPlot UDP comm link success

I had some recent success setting up a WiFi UDP communications link between an Arduino UNO and a MakerPlot application running on a nearby PC. I’m using the Sparkfun ESP8266 shield for WiFi support.

The Arduino sketch automates logon to the WiFi network, sets up the UDP link and puts it in transparent mode, then generates a bunch of “!POBJ led_red=1” etc MakerPlot control commands to animate the demo graphics display.

I’m using a small home brew library to wrap the AT commands to control the ESP8266 shield which uses a software serial link to communicate with the UNO.

If there is any interest in this let me know and I’ll post more about it. It’s not done yet by any means, but seems to be working ok now.
