Adafruit Feather HUZZAH connection props

Hello,

I’m desperately trying to connect one of my small fantastic microcontrollers to the Blynk app. I’ve heard so much good about it, but until now it has been a disaster.

I’m trying to connect an Adafruit Feather HUZZAH with the simple Blynk example “NodeMCU” in the Arduino IDE. Im following this guide:

It connects to the Wifi with ease, but the “Invalid auth token” message haunts me!
I saw in another post, that sometimes there is “hidden” spaces before the Auth token, and it helped him, so i wrote the whole auth token in myself, but nothing. I’m using Blynk library version 1.0.1 and all else should be default.

First i tried a lot of times with my ESP8266-01. It got a lot of different errors, and i fought my way through them, only to get stoppet by the same message. “Invalid Auth token”. Over and over again. It puzzles me.


/* Fill-in your Template ID (only if using Blynk.Cloud) */
//#define BLYNK_TEMPLATE_ID   "TMPLGs2iTlEw"


#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "WjhEYjUd6kF0TYwGTD5KUnACrqqX1FaU";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "PrettyFlyForAWIFI";
char pass[] = "********";

void setup()
{
  // Debug console
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
}

void loop()
{
  Blynk.run();
}

Are you using Blynk Legacy (Blynk 0.1) or New Blynk (Blynk IoT) ?

Pete.

Better be 2.0. Never seen an auth code like that in Legacy.

Hello Pete,

I’m using the new Blynk.
