Hi Everyone!

I would like to write down my experience regarding the communication between Arduino and ESP8266 UART WIFI shield in this article.

I don’t say that it is the best solution, but it’s working, so I hope this description will be helpful for you.

Let’s get started.

I had used my Arduino UNO with ethernet shield, but it wasn’t flexible. I had to place it near to the router or I had to use a long ethernet wire. It wasn’t so practical.

So I decided to search for another solution. I have ordered a wireless ethernet shield from AliExpress for my Arduino. This shield is called ESP8266 ESP-12E UART WIFI Wireless Shield Development Board For Arduino UNO R3 (Quite long name :-) )

When I received this shield I thought that I just connect it to the Arduino, use some kind of predefined library in the Arduino IDE and it will work. Well, I had mistaken.

So I had started to search for solutions on the web, but unfortunately I didn’t find any useful helps. There were only questions without answers.

Finally I found two web sites, what helped me to find out how can I use this shield:

• http://blog.jeronimus.net/2016/07/esp8266-wangtongze-arduino-uno-shield.html
• http://nicuflorica.blogspot.hu/2016/09/placa-de-retea-wifi-shield-cu-esp8266mod.html

On the first site the author explains how can you upload your own code to the ESP8266. This type of microcontroller is on the WIFI shield.

On the second web site you can read some information about the communication between Arduino and ESP8266 via this shield. (Unfortunately I didn’t know the language what this side is written so I had translated it with Google translator. I don’t say that everything was clear for me, but I think I understood the essence of this article.)

These two sides didn’t give the final solution for me, but helped a lot, so thanks for the authors for these articles.

OK, let’s go back to the problem. How can we use these shield?

I will walk through an example I think this is the best way to understand how it works.
