esp8266 wifi.localip() to string

To convert the result of wifi.localIP() to a string in C++, you can follow these steps:

1. Step 1: Call the wifi.localIP() function to obtain the IP address as an IPAddress object. The localIP() function is provided by the ESP8266WiFi library and it retrieves the IP address assigned to the ESP8266 module.

2. Step 2: Convert the IPAddress object to a String object. To do this, you can use the toString() method of the IPAddress class, which returns a string representation of the IP address.

Here's an example code snippet that demonstrates these steps:

#include <ESP8266WiFi.h>

void setup() {
  // Connect to WiFi network

  // ...

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

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

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

void loop() {
  // ...
}

In this example, the wifi.localIP() function retrieves the IP address assigned to the ESP8266 module. The IPAddress object ip stores this IP address. Then, the toString() method is called on the ip object to convert it to a string, which is stored in the ipString variable. Finally, the IP address is printed using Serial.println().

This code will print the IP address of the ESP8266 module in the serial monitor.
