ESP8266 Arduino-Core Tutorial – Web Server

TCP Server Listener

The below Arduino code will also create a server and Access Point in ESP8266 which will continuously listen for a connection.

Code

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>

const char *ssid = "ArunEworld";
const char *password = "Arun";

ESP8266WebServer server(80);

void handleRoot() 
{
    server.send(200, "text/html", "<t1>ArunEworld</t1>");
    server.send(200, "text/html", "<h1>ArunEworld : TCP WebServer Listener</h1>");
    server.send(200, "text/html", "<h2>You are connected</h2>");
}

void setup()
{
    delay(1000);
    Serial.begin(115200);
    Serial.println();
    Serial.print("Configuring access point...");
    WiFi.softAP(ssid, password);
    IPAddress myIP = WiFi.softAPIP();
    Serial.print("AP IP address: ");
    Serial.println(myIP);
    server.on("/", handleRoot);
    server.begin();
    Serial.println("HTTP server started");
}

void loop() 
{
    server.handleClient();
}

After uploading this sketch, you can find a new Access Point named “test” from your Laptop or PC.
