Arduino Mega 2560 + ESP8266 shield Blynk.connectWiFi(ssid, pass) command not working

My main problem is still to manage if the internet connection is available or not. So I just want my code to work whatever the Wifi state and reconnect when available.

I simply use this set of commands in all my Blynk sketches…

  WiFi.begin(ssid, pass);  // Non-blocking if no WiFi available
  Blynk.config(auth, server, port);
  Blynk.connect();

Using an ESP as shield can be different then as standalone, but the principle is usually the same…

I use this in my MEGA & ESP-01 sketch…

How ton run program without connected to wifi or internet, use blynk only to monitor when it required

In reference to both your topics about these libraries… This is part of your issue… The ESP8266 in your case is ONLY acting as a Serial to WiFi transceiver (AKA as Shield), thus it uses different libraries and has different functions then a full standalone ESP8266. I also use a Mega with ESP as shield… and am able to run without Blynk connection via this code… This is for an auto reconnection routine… #include <WiFi.h> #include <ESP8266_Lib.h> // ESP-01 Link #include <BlynkSimpleShieldEsp8…
