Has anyone used this shield? I believe it requires a different sketch.
I have not, but you can still program it standalone, and use the sketch in the HowTo.
You only need a different sketch if you plan on putting a sketch in the Uno and using the ESP as a shield.
I posted some tips on doing this, but I can’t remember if I tested it myself.
Will see what I can throw together this week.
The ESP13 from Doit.am is a Arduino Uno Wifi shield. So I am wiring code the Arduino and using the ESP13 as a Wifi shield.
It does not require you to connect to the SSID as this does by using a configuration page on it’s built in web server.
I have been less than successful talking to it from the UNO
Are you OK using mqtt? I have an arduino uno wifi from .org which is very similar to what you described. I can try to get a sketch working on it with mqtt and share it with you of that will work?
I had to google what mitt was, but that should work. I can certainly give
it a go.
These shields are very inexpensive from ebay/China so if you can figure it
out, I suspect there would be many others interested.
