arduino wifi ip address to string

To convert an Arduino WiFi IP address to a string, you can use the toString() function. Here's an example:

#include <WiFi.h>

void setup() {
  Serial.begin(115200);

  // Connect to WiFi
  WiFi.begin("yourSSID", "yourPassword");

  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }

  // Get the IP address
  IPAddress ip = WiFi.localIP();

  // Convert IP address to string
  String ipString = ip.toString();

  // Print the IP address as a string
  Serial.println(ipString);
}

void loop() {
  // Do something
}

This code connects to a WiFi network and retrieves the local IP address. It then converts the IP address to a string using the toString() function and prints it to the serial monitor. You can replace "yourSSID" and "yourPassword" with your own network SSID and password.

Make sure to include the WiFi library at the beginning of your code.
