In attempt to solve a PHP texting issue I have tried using the ESP32Ping library in an app to determine if the domain in question can be reached or pinged.

PROBLEM - If I include the correct IP address in the 'remote_ip() variable I get 'Success!!'. If I leave that same variable blank (" "), I still get 'Success!!'. This makes no sense to me so I my code must not be correct. Any help will be greatly appreciated.

Here is my sketch:

Code: Select all


#include "config.h"
#include <WiFi.h>
#include <ESP32Ping.h>

const IPAddress remote_ip(" ");

void connect_wifi() 
  {
        Serial.println();
        Serial.println();
        Serial.print("Connecting to ");
        Serial.println(ssid);

        WiFi.begin(ssid, password);

        while (WiFi.status() != WL_CONNECTED) {
            delay(500);
            Serial.print(".");
          }
          
        Serial.println("");
        Serial.println("WiFi Connected!\n");
        Serial.print("IP address: ");
        Serial.print(WiFi.localIP());
        Serial.println();
  }

void setup() {
  Serial.begin(115200);   delay(1000);
  connect_wifi();       delay(1000); 
}


void loop() { 
  if(Ping.ping(remote_ip)) {
    Serial.println("Success!!");
  } else {
    Serial.println("Error :(");
  }
  delay(15000);
}
