How can I connect to bylnk with esp32 cam?

Need Help With My Project

Hello, @Haydar We will provide ESP32 CAM examples later. It is in the plans.

You can use the local server example in the Arduino IDE examples. And add a connection to the Blynk in sketch.

Some example for ESP32 CAM

// *** MAIN SETTINGS ***
// Replace this block with correct template settings.
// You can find it for every template here:
//
//   https://blynk.cloud/dashboard/templates

#define BLYNK_TEMPLATE_ID     "TMPxxxxxx"
#define BLYNK_TEMPLATE_NAME   "Device"
#define BLYNK_AUTH_TOKEN      "YourAuthToken"

// Your WiFi credentials.
// Set password to "" for open networks.
#define WIFI_SSID             "YourNetworkName"
#define WIFI_PASS             "YourPassword"

#define BLYNK_PRINT Serial  // Comment this out to disable serial monitor prints

// Adding the required libraries
#include "esp_camera.h"
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>


#define CAMERA_MODEL_AI_THINKER // Has PSRAM
