Hi, I’d like use the ESP8266 ( this version:http://www.banggood.com/fr/ESP8266-Remote-Serial-Port-WIFI-Transceiver-Wireless-Module-p-947259.html). I don’t know how can I use it, does somebody can help me or do a tutorial?^^
thanks 
That is a very open ended question, but there is a blynk example labeled “esp8266 standalone” that gets you started using blynk on this chip. For general questions about how to program chip you should check out esp8266.com or learn.adafruit.com
Hi,
you can start with two ways.
a.with blink server
b.with local server
just follow the below link. I can help you if you have any doubt on it.
