NodeMCU V3 ESP8266
WiFi Modes of Operation of ESP8266: There are three modes of WiFi Operation in the ESP8266 WiFi Module. Those are:
- Station Mode (STA)
- Soft Access Point (AP)
- Soft AP + Station
Station Mode

const char* password = "academia";

WiFi.begin(ssid, password);
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);

delay(1000);
}
Soft Access Point
