I have this material :

I Install :
Blynk library
In preference I past
https://arduino.esp8266.com/stable/package_esp8266com_index.json
In Tools I have correctly selected my [b]generic esp8266 module[/b]
My code:
/*************************************************************
Download latest Blynk library here:
https://github.com/blynkkk/blynk-library/releases/latest
Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

This example code is in public domain.
*************************************************************
This example runs directly on ESP8266 chip.
Note: This requires ESP8266 support package:
https://github.com/esp8266/Arduino
Please be sure to select the right ESP8266 module
in the Tools -> Board menu!
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!

[pre]Normally I have to do as in the picture is insert the key at the same time but I don't have the impression that it works
and I have a feeling that it is not detected because on any place where I plug it. I only detect COM1[/pre]
