Code to Re-Connect Blynkserver Automatically

Issue: Sometimes the hardware(eg. Nodemcu) doesn't connect to router automatically, when there is a break in connection.

Solution: 

In this we'll add a timer. When there is no connection, the timer will start and try to reconnect in every specified time interval. to make this happen we need a library called as simple timer.

#Simple timer library: https://github.com/schinken/SimpleTimer

Extract this library to the library folder in Arduino folder in my documents.

Write the  following code:

#include <SimpleTimer.h>

#include <ESP8266WiFi.h>

#include <BlynkSimpleEsp8266.h>

SimpleTimer timer;    //Creating simple timer variable 

char auth[] = "MxLDc********************KtUI";

char ssid[] = "**********";

char pass[] = "**********";

void setup()

{

  

  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);

  timer.setInterval(10000, reconnectBlynk); //Setting interval to 10 seconds to Run function"reconnectBlynk"

}

void reconnectBlynk() {

  if (!Blynk.connected()) {

    if(Blynk.connect()) {

      BLYNK_LOG("Reconnected");

    } else {

      BLYNK_LOG("Not reconnected");

    }

  }

}

void loop()

{

  

  if (Blynk.connected()) {

    Blynk.run();

  }

  if (!Blynk.connected()) {

    timer.run();

  }

}
