Communicating with esp32 Via WiFi

Hello everyone. I'm trying to communicate with the ESP32 Via wifi.
I only know how to send one set of instructions. For example, opening this link "," on my browser sets the Led on pin5 High. What I want to do is pass two or more variables. For example ",160". split the last part to "Character" and "Number".

Now, I googled this but all the solutions I got involved some pretty advanced web development that I did not understand.

The Code is supposed to look something like this:

if (currentLine.endsWith("GET /Char,And#")) { //Here "Char" and "#" are variables that could have multiple values.

Here is the code that works with one variable:

#include <WiFi.h>

const char* ssid     = "wifissid";
const char* password = "password";
IPAddress local_IP(192, 168, 1, 115);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 0, 0);
IPAddress primaryDNS(1, 1, 1, 1); //optional
IPAddress secondaryDNS(1, 0, 0, 1); //optional

WiFiServer server(80);

void setup()
  pinMode(5, OUTPUT);      // set the LED pin mode
  if (!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {
    Serial.println("STA Failed to configure");


  // We start by connecting to a WiFi network

  Serial.print("Connecting to ");

  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {

  Serial.println("WiFi connected.");
  Serial.println("IP address: ");



int value = 0;

void loop() {
  WiFiClient client = server.available();   // listen for incoming clients

  if (client) {                             // if you get a client,
    Serial.println("New Client.");           // print a message out the serial port
    String currentLine = "";                // make a String to hold incoming data from the client
    while (client.connected()) {            // loop while the client's connected
      if (client.available()) {             // if there's bytes to read from the client,
        char c =;             // read a byte, then
        Serial.write(c);                    // print it out the serial monitor
        if (c == '\n') {                    // if the byte is a newline character

          // if the current line is blank, you got two newline characters in a row.
          // that's the end of the client HTTP request, so send a response:
          if (currentLine.length() == 0) {
            // HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
            // and a content-type so the client knows what's coming, then a blank line:
            client.println("HTTP/1.1 200 OK");

            // the content of the HTTP response follows the header:
            client.print("Click <a href=\"/H\">here</a> to turn the LED on pin 5 on.<br>");
            client.print("Click <a href=\"/L\">here</a> to turn the LED on pin 5 off.<br>");

            // The HTTP response ends with another blank line:
            // break out of the while loop:
          } else {    // if you got a newline, then clear currentLine:
            currentLine = "";
        } else if (c != '\r') {  // if you got anything else but a carriage return character,
          currentLine += c;      // add it to the end of the currentLine

        // Check to see if the client request was "GET /H" or "GET /L":
        if (currentLine.endsWith("GET /H,")) {
          digitalWrite(5, HIGH);               // GET /H turns the LED on
        if (currentLine.endsWith("GET /L,")) {
          digitalWrite(5, LOW);                // GET /L turns the LED off
    // close the connection:
    Serial.println("Client Disconnected.");

If you have every looked at http, you will see that parameters are normally passed as pairs

Look at the example that come with the wifi library

Thanks For your reply.
I went through all the examples that come with the WiFi library. I can't find the example that you mentioned.

Look at the WifiManager library
