ESP286612E DEV KIT doit.am - BLYNK won`t connect to WiFi

Bugs / Issues

Hello friends,

i`m having issues connecting with my ESP286612E DEV KIT to my WiFi router. It is simple sketch i want to run and control via cayenne dashboard.
The code:

#define CAYENNE_DEBUG         // Uncomment to show debug messages
#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space

#include "CayenneDefines.h"
#include "BlynkSimpleEsp8266.h"
#include "CayenneWiFiClient.h"

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "<8qghxxxxx>";
// Your network name and password.
char ssid[] = "<Zombie>";
char password[] = "<zoxxxxxxm>";

void setup()
{
  // initialize digital pin 2 as an output.
  pinMode(2, OUTPUT);
  Serial.begin(9600);
  Cayenne.begin(token, ssid, password);
}

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

// This function will be called every time a Dashboard widget writes a value to Virtual Pin 2.
CAYENNE_IN(V2)
{
  CAYENNE_LOG("Got a value: %s", getValue.asStr());
  int i = getValue.asInt();
  
  if (i == 0)
  {
    digitalWrite(2, LOW);
  }
  else
  {
    digitalWrite(2, HIGH);
  }  
}

I cant get far from serial port message:

So dashboard is waiting and waiting for board to connect…

I use:

  • Arduino IDE 1.6.12
  • NODEMCU 1.0 (ESP 12-E module)
  • ESP2866 board version 2.3.0

When “helloServer”[ESP2866WebServer] tested - it was done with no problem.

Hi @lxmatic ,

You shouldn’t use the < and > characters in your strings.

Also, can you try it without setting the pinMode first or use another pin? Some of the ESP pins have special functions and sometimes exhibit odd behavior.

Cheers,

Huh… what a mistake… THANK YOU Craig a BIG TIME :slight_smile: removing “<>” characters did the job.

Great!

If you see strange issues like resets, or outputs turning on without you setting them, try another pin.

Cheers,

Craig
