ESP32 WROVER - Lack of Photo Memory

By -

Good afternoon everyone, how are you?

I'm using an ESP32 WROVER

I just need to put it on the network and take a picture (good quality) In the description it says that the card has 4mb flash memory, but when I go to record it appears as follows Flash: [====== ] 64.5% (used 845098 bytes from 1310720 bytes) that is, it has only 1.3mb

A high resolution photo needs 1mb, but as it has no memory, it gives an error.

Follow my program

#include <WiFi.h>
#include <ESP_WiFiManager.h>
#include <esp_camera.h>
#include <WiFiServer.h>

const char* ssid = "ESP_Laser";
const char* password = "Laser123";

WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  delay(10);

  ESP_WiFiManager WiFiManager;
  WiFiManager.setConfigPortalTimeout(240);

  if (!WiFiManager.autoConnect(ssid, password)) {
    Serial.println("Falha na conexao. Resetar e tentar novamente...");
    delay(3000);
    ESP.restart();
    delay(5000);
  }

  Serial.println("Conectado na rede WiFi.");
  Serial.print("Endereco IP: ");
  Serial.println(WiFi.localIP());

  camera_config_t config;

  config.pin_pwdn = -1;
  config.pin_reset = -1;  
  config.pin_xclk = 21;
  config.pin_sscb_sda = 26;
  config.pin_sscb_scl = 27;

  config.pin_d7 = 35;
  config.pin_d6 = 34;
  config.pin_d5 = 39;
  config.pin_d4 = 36;
  config.pin_d3 = 19;
  config.pin_d2 = 18;
  config.pin_d1 = 5;
  config.pin_d0 = 4;
  
  config.pin_vsync = 25;
  config.pin_href = 23;
  config.pin_pclk = 22;

  config.xclk_freq_hz = 20000000;
  config.ledc_timer = LEDC_TIMER_0;
  config.ledc_channel = LEDC_CHANNEL_0;
  
  config.pixel_format = PIXFORMAT_JPEG;
  config.frame_size = FRAMESIZE_UXGA;

  config.jpeg_quality = 10;
  config.fb_count = 2;

  esp_err_t cameraInitError = esp_camera_init(&config);
  if (cameraInitError != ESP_OK) {
    Serial.printf("Falha na inicialização da câmera! (erro 0x%x)\n", cameraInitError);
    return;
  }

  server.begin();
  Serial.println("Servidor iniciado.");

}

void loop() {
  WiFiClient client = server.available();
  if (!client) {
    return;
  }

  Serial.println("Novo cliente conectado.");

  camera_fb_t* fb = esp_camera_fb_get();
  if (!fb) {
    client.println("HTTP/1.1 500 Internal Server Error");
    client.println("Content-type:text/html");
    client.println();
    client.println("<html><body><h1>Erro ao capturar imagem</h1></body></html>");
    delay(1);
    client.stop();
    return;
  }

  client.println("HTTP/1.1 200 OK");
  client.println("Content-type:image/jpeg");
  client.println("Connection: close");
  client.println();
  client.write(fb->buf, fb->len);
  esp_camera_fb_return(fb);

  delay(1);
  client.stop();
}

I was disappointed because I thought that this board would be able to take only 1 photo in good resolution. Is there still a way to do this? or would I need to buy the card that comes with space to put a memory card? Thanks

Would I need to buy a new board with a memory card or is there still a way to do this one?

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk.

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();     TransportClient client = new P
