the ESP32-Cam sent a foto with the following sketch:
void take_picture() {
camera_fb_t * fb = NULL; // pointer
Serial.println("Taking a photo...");
fb = esp_camera_fb_get();
if (!fb) {
Serial.println("Camera capture failed");
return;
}
if (MQTT_MAX_PACKET_SIZE == 128) {
//SLOW MODE (increase MQTT_MAX_PACKET_SIZE)
client.publish_P("door/photo", fb->buf, fb->len, false);
Serial.print("SLOW MODE ");
}
else {
//FAST MODE (increase MQTT_MAX_PACKET_SIZE)
client.publish("door/photo", fb->buf, fb->len, false);
Serial.print("FAST MODE ");
}
Serial.print(" message and Foto sent... ");
esp_camera_fb_return(fb);
}
the ESP-Cam show's in the serial-monitor a successful capture and sending

the ESP32-Cam ist tested, as a http-Webserver he are sending normal pictures
Examples in Github: botabotlab/ ESP32CAM-MQTT also doesn't show's a picture in the Dashboard/Template - and - tested by an independent body with the same result, no photo in the template!
many thanks in advance for further informations
