arduino ide 用esp32-cam做一个蓝牙无线监控的代码

好的，以下是一个基本的 Arduino 代码，用于将 ESP32-CAM 连接到蓝牙并实现无线监控：

#include "esp_camera.h"
#include <BluetoothSerial.h>

// Define the camera pins
#define CAM_PIN_PWDN 32
#define CAM_PIN_RESET -1
#define CAM_PIN_XCLK 0
#define CAM_PIN_SIOD 26
#define CAM_PIN_SIOC 27
#define CAM_PIN_D7 35
#define CAM_PIN_D6 34
#define CAM_PIN_D5 39
#define CAM_PIN_D4 36
#define CAM_PIN_D3 21
#define CAM_PIN_D2 19
#define CAM_PIN_D1 18
#define CAM_PIN_D0 5
#define CAM_PIN_VSYNC 25
#define CAM_PIN_HREF 23
#define CAM_PIN_PCLK 22

// Create a BluetoothSerial object
BluetoothSerial SerialBT;

void setup() {
  Serial.begin(115200);

  // Initialize the camera
  camera_config_t config;
  config.ledc_channel = LEDC_CHANNEL_0;
  config.ledc_timer = LEDC_TIMER_0;
  config.pin_d0 = CAM_PIN_D0;
  config.pin_d1 = CAM_PIN_D1;
  config.pin_d2 = CAM_PIN_D2;
  config.pin_d3 = CAM_PIN_D3;
  config.pin_d4 = CAM_PIN_D4;
  config.pin_d5 = CAM_PIN_D5;
  config.pin_d6 = CAM_PIN_D6;
  config.pin_d7 = CAM_PIN_D7;
  config.pin_xclk = CAM_PIN_XCLK;
  config.pin_pclk = CAM_PIN_PCLK;
  config.pin_vsync = CAM_PIN_VSYNC;
  config.pin_href = CAM_PIN_HREF;
  config.pin_sscb_sda = CAM_PIN_SIOD;
  config.pin_sscb_scl = CAM_PIN_SIOC;
  config.pin_pwdn = CAM_PIN_PWDN;
  config.pin_reset = CAM_PIN_RESET;
  config.xclk_freq_hz = 20000000;
  config.pixel_format = PIXFORMAT_JPEG;
  if (psramFound()) {
    config.frame_size = FRAMESIZE_UXGA;
    config.jpeg_quality = 10;
    config.fb_count = 2;
  } else {
    config.frame_size = FRAMESIZE_SVGA;
    config.jpeg_quality = 12;
    config.fb_count = 1;
  }
  esp_err_t err = esp_camera_init(&config);
  if (err != ESP_OK) {
    Serial.printf("Camera init failed with error 0x%x", err);
    return;
  }

  // Initialize the BluetoothSerial object
  SerialBT.begin("ESP32-CAM");
}

void loop() {
  // Capture a frame from the camera
  camera_fb_t *fb = esp_camera_fb_get();
  if (!fb) {
    Serial.println("Camera capture failed");
    return;
  }

  // Send the frame over Bluetooth
  SerialBT.write(fb->buf, fb->len);

  // Release the frame buffer
  esp_camera_fb_return(fb);

  // Wait 50ms before capturing the next frame
  delay(50);
}

此代码使用 ESP32-CAM 模块连接到蓝牙，并从摄像头捕获图像，并通过蓝牙发送它们。请注意，此代码假定您已经将 ESP32-CAM 配置为连接到 WiFi 并具有 Internet 访问权限。如果您还没有完成此操作，您需要先完成此操作。
