## 📦 ESP32 Camera Stream Code (HTML + Stream Endpoint)
This is a working local server (LAN) that connects to Mobile/Router WiFi and serves a camera preview page with a placeholder stream:
```cpp
#include
#include
const char* ssid = "spa";
const char* password = "12345678";
AsyncWebServer server(80);
void setup() {
Serial.begin(115200);
// Connect to WiFi (Station Mode)
WiFi.begin(ssid, password);
Serial.print("Connecting to WiFi");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("\nConnected to WiFi!");
Serial.println("IP Address: ");
Serial.println(WiFi.localIP());
// HTML Page
server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){
String html = R"rawliteral(
ESP32 OV7670 Stream
ESP32 Camera Stream
)rawliteral";
request->send(200, "text/html", html);
});
// Placeholder stream
server.on("/stream", HTTP_GET, [](AsyncWebServerRequest *request){
// This will be replaced with image data later
request->send(200, "image/jpeg", "", 0);
});
server.begin();
}
void loop() {
// No code here for now
}
```
