Code Examples

### Example 1: Connecting to a Wi-Fi Network using Arduino IDE

This example demonstrates how to connect the ESP8285 Wi-Fi SoC Module to a Wi-Fi network using the Arduino IDE.

```cpp
#include <WiFi.h>

const char ssid = "your_wifi_ssid";  // Replace with your Wi-Fi SSID
const char password = "your_wifi_password";  // Replace with your Wi-Fi password

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to Wi-Fi...");
  }
  Serial.println("Connected to Wi-Fi");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // Your application code here
}
```

### Example 2: Sending Data to a Web Server using ESP8285 as a Client

This example demonstrates how to send data to a web server using the ESP8285 Wi-Fi SoC Module as a client.

```cpp
#include <WiFi.h>
#include <WiFiClient.h>

const char ssid = "your_wifi_ssid";  // Replace with your Wi-Fi SSID
const char password = "your_wifi_password";  // Replace with your Wi-Fi password
const char serverUrl = "http://example.com/data";  // Replace with your web server URL

WiFiClient client;

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to Wi-Fi...");
  }
  Serial.println("Connected to Wi-Fi");
}

void loop() {
  if (WiFi.status() == WL_CONNECTED) {
    if (client.connect(serverUrl, 80)) {
      String sendData = "data=temperature&value=25.5";
      client.println("POST " + String(serverUrl) + " HTTP/1.1");
      client.println("Host: " + String(serverUrl));
      client.println("Content-Type: application/x-www-form-urlencoded");
      client.println("Content-Length: " + String(sendData.length()));
      client.println();
      client.print(sendData);
      client.stop();
    } else {
      Serial.println("Failed to connect to server");
    }
  }
  delay(5000);
}
```

### Example 3: Creating a Simple Web Server using ESP8285 (using MicroPython)

This example demonstrates how to create a simple web server using the ESP8285 Wi-Fi SoC Module with MicroPython.

```python
import network
import socket

# Initialize Wi-Fi
sta_if = network.WLAN(network.STA_IF)
sta_if.active(True)
sta_if.connect("your_wifi_ssid", "your_wifi_password")

# Create a socket object
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Bind the socket to a address and port
sock.bind(('', 80))

# Listen for incoming connections
sock.listen(5)

print("Web server started on port 80")

while True:
    conn, addr = sock.accept()
    request = conn.recv(1024)
    response = "HTTP/1.1 200 OK
Content-Type: text/html

" + "<h1>Hello, World!</h1>"
    conn.send(response)
    conn.close()
```

Note: These examples are for demonstration purposes only and may require modifications to suit your specific use case. Ensure to update the Wi-Fi SSID, password, and server URL as needed.
