After we have successfully connetcted to wifi the next step is test our connection to internet or specific ip. i am using additional library to do ping job, and the as below :
#include <Arduino.h>
#include <WiFi.h>
#include <ESP32Ping.h>
String wifiSSID = "smartbuilding_wifi";
String wifiPassword = "smartbuilding@2020";
String googlDotCom = "www.google.com";
void setup()
{
Serial.begin(9600);
Serial.println("Connecting To Wifi");
WiFi.begin(wifiSSID.c_str(), wifiPassword.c_str());
while (WiFi.status() != WL_CONNECTED)
{
Serial.print(".");
delay(500);
}
Serial.println("Wifi Connected");
Serial.println(WiFi.SSID());
Serial.println(WiFi.RSSI());
Serial.println(WiFi.macAddress());
Serial.println(WiFi.localIP());
Serial.println(WiFi.gatewayIP());
Serial.println(WiFi.dnsIP());
if (Ping.ping(googlDotCom.c_str()))
{
Serial.println("Connected to Router");
}
}
void loop()
{
