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.
