ESP13 Shield from Doit.am Supported?

[george2]

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.

Try this:

WifiShield with arduino uno compiling error

If you are using the ESP8266 as a Wifi shield with the AT command set installed on the ESP, and the Uno as the host, then this will not work. @adam is talking about overwriting the flash in the ESP module itself so you don’t even need an Uno. Connect your Uno serial port RX to TX and TX to RX on the ESP. Note that the ESP pins are 5V tolerant, but if you want to be nice, put a 1K resistor inline between the Uno TX and the ESP RX. Also note that the ESP supply must be 3.3V. If you put 5V there,…

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.

Thanks.
