Hi.
I’m having a problem with the auth token, i was trying to control my Arduino Uno board through Blynk with the Nodemcu ESP8266. I was following a guide on arduino project hub and the auth token i have was invalid. It’s my fist time using Blynk and Nodemcu so if anyone could help me i’ll be very grateful.

*************************************************************
This example shows how to use ESP8266 Shield (with AT commands)
to connect your project to Blynk.
WARNING!
It's very tricky to get it working. Please read this article:
http://help.blynk.cc/hardware-and-libraries/arduino/esp8266-with-at-firmware
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!
