### Wi-Fi Access Point Mode
In **Access Point mode (AP)**, the ESP32 acts as a Wi-Fi access point, creating its own Wi-Fi network that other devices can join. This mode works similarly to a wireless router, allowing multiple clients to connect to the ESP32.
ESP32 can host a simple web server in AP mode. Devices connecting to the ESP32 can access a web page, making this mode ideal for local control interfaces, configuration pages, or monitoring systems.
ESP32 AP mode can handle up to 4 simultaneous connections.
```cpp
#include
// Set the SSID and password for the ESP32's Access Point
const char* ssid = "LonelyBinaryESP32AP";
const char* password = "123456789"; // Minimum 8 characters
void setup() {
// Start serial communication
Serial.begin(115200);
Serial.println("Setting up Access Point...");
// Set up the Access Point
WiFi.softAP(ssid, password);
// Print the IP address of the ESP32 in AP mode
Serial.print("Access Point IP Address: ");
Serial.println(WiFi.softAPIP());
}
void loop() {
// Nothing to do here, the ESP32 is in AP mode
}
```
```cpp
WiFi.softAP(ssid, password);
```
This function configures the ESP32 to operate in **Access Point (AP) mode**. By calling this function, the ESP32 will create a local Wi-Fi network with the specified SSID and password, and devices can connect to it directly.
```cpp
WiFi.softAPIP()
```
WiFi.softAPIP() is a function that returns the IP address of the ESP32’s Access Point (AP) interface. By default, the **ESP32 AP’s IP address** is usually 192.168.4.1. The DHCP server is enabled by default, meaning that all connected wireless clients will have their IP addresses assigned automatically.
