WiFi Access Point

A virtual component that provides a simulated wireless network for Wi-Fi capable microcontrollers (like the ESP32) to connect to.

Component Preview

Virtual AP

Unlike physical components, the WiFi Access Point exists solely to emulate a network environment in the simulator. By adding this to your project, microcontrollers can scan for its SSID and connect to it, simulating real-world IoT behavior without requiring physical hardware.

Logic ComponentsVirtualNetworking

Overview

Because this is a virtual networking element, it does not have physical pins. You configure its SSID and password in the diagram.json attributes. Once running, ESP32 or ESP8266 code can connect to it using standard Wi-Fi libraries.

Pin Reference

This component is virtual and does not have any physical pins.

Configurable Attributes

Attribute	Type	Default	Description
ssid	string	"Wokwi-GUEST"	The network name broadcasted by the AP.
password	string	""	The password required to connect (leave empty for open networks).
channel	number	6	The simulated Wi-Fi channel (1-14).
internet	boolean	true	If true, the simulated AP provides routed access to the public internet.

Example ESP32 Code

This sketch demonstrates how to connect to the simulated access point.

#include <WiFi.h>

// Match these with the AP attributes in your diagram.json
const char* ssid = "Wokwi-GUEST";
const char* password = "";

void setup() {
  Serial.begin(115200);
  Serial.println("Connecting to WiFi...");

  // Begin connection
  WiFi.begin(ssid, password);

  // Wait until connected
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected!");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // Your internet-connected code here
  delay(1000);
}

Simulation Notes

• The OpenHW Simulator intercepts Wi-Fi requests from the ESP32 and routes them through the browser's networking stack, allowing you to fetch real data from external APIs via the simulated internet: true property. (Subject to CORS restrictions).
