WiFi Modes of Operation of ESP8266: There are three modes of WiFi Operation in the ESP8266 WiFi Module. Those are:

  1. Station Mode (STA)
  2. Soft Access Point (AP)
  3. Soft AP + Station

Station Mode

Only Access Point

#include "ESP8266WiFi.h"

const char* ssid = "ChorkeOrg_2.4GHz";
const char* pass = "academia";

void setup(void) {
  pinMode(D4, OUTPUT);
  Serial.begin(115200);
  WiFi.begin(ssid, pass);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print("*");
  }

  Serial.println("");
  Serial.println("WiFi connection Successful");
  Serial.print("The IP Address of ESP8266 Module is: ");
  Serial.print(WiFi.localIP());
}

void loop() {
  digitalWrite(D4, LOW);
  delay(1000);
  digitalWrite(D4, HIGH);
  delay(1000);
}

Multi Access Point

#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>

const char* ap0_ssid_50 = "ChorkeOrg";
const char* ap0_pasword = "chorke@bd/0A";
const char* ap0_ssid_24 = "ChorkeOrg_2.4GHz";

ESP8266WiFiMulti multi;

void setup(void) {

  Serial.begin(115200);

  Serial.println('\n');

  while (multi.run() != WL_CONNECTED) {

  }
  Serial.println('\n');
  Serial.print("Connected to: ");
  Serial.println(WiFi.SSID());
  Serial.print("IP address  : ");

}

void loop() {
  digitalWrite(D4, LOW);
  delay(1000);
  digitalWrite(D4, HIGH);
  delay(1000);
}

Soft Access Point

#include "ESP8266WiFi.h"

const char* ssid = "ChorkeIot_2.4GHz";
const char* pass = "academia";

IPAddress local_IP(10, 10, 10, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress gateway(10, 10, 10, 1);

void setup(void) {
  pinMode(D4, OUTPUT);
  Serial.begin(115200);
  Serial.println();

  Serial.print("WNC Config: ");
  Serial.print(WiFi.softAPConfig(local_IP, gateway, subnet) ? "Ready" : "Failed!");

  Serial.println("SID Config: ");
  Serial.print(WiFi.softAP(ssid, pass) ? "Ready" : "Failed!");

  Serial.println("WAN Config: ");
  Serial.print(WiFi.softAPIP());
}

void loop() {
  digitalWrite(D4, LOW);
  delay(1000);
  digitalWrite(D4, HIGH);
  delay(1000);
}

Duel Mode

#include <ESP8266WiFi.h>
