Summary


  • Added support of the jpg EXIF metadata
  • Added TimeLaps function
  • Added Micro SD card status and usage
  • Changed ESPAsyncWebServer library
  • Change of logging to the file
  • Added title of the page configuration
  • Added button to start the live-stream
  • Bug fixes and web design improvement

This is a stable version for the ESP32-cam

To apply the new settings on the web interface, it is necessary to clear the cache of the camera's web page. The cache is valid for 24 hours, so it will automatically refresh after 24 hours.

Added support of the jpg EXIF metadata


Support for EXIF metadata for jpg images has been added. Thanks to this, it is possible to rotate the camera image by 0, 90, 180, or 270 degrees. The OV2640 camera module does not generate EXIF metadata. Therefore, it is necessary to calculate the EXIF metadata and add it to the image. The library for generating EXIF metadata is taken from user @dimhoff from his project ESP32-CAM_Interval. EXIF metadata is not currently added for the stream

camera_screen

Added TimeLaps function


It is possible to enable saving the photos sent to Prusa Connect onto a micro SD card (formated to FAT32). Photos are saved on the micro SD card, in the folder timelaps. After successfully completing the print, it is necessary to remove the micro SD card from the camera and copy the saved photos from the card. The next, it is necessary to use SW to create a timelapse video from photos.

Added Micro SD card status and usage


The status of the micro SD card and usage are displayed in the system page.

system_screen

Changed ESPAsyncWebServer library


Initially, the ESPAsyncWebsrv library by user dvarrel was used. Currently is used another library, ESPAsyncWebServer by user mathieucarbou. The new library has better stability according to tests, is more optimized, and is compatible with ESP-IDF 5.1.

Change of logging to the file


Logging to a file on the micro SD card has been improved. Thanks to this, RAM memory is more optimized, and the speed and stability of the firmware are increased.

Added title of the page configuration


The mDNS record is simultaneously used as the title for the camera's web page in the browser. Currently, mDNS is used for three functions:

  • mDNS record
  • Camera name in Prusa Connect
  • Browser title

mdns title

Added button to start the live-stream


Added a button on the webpage below Download snapshot to open the live-stream URL, improving accessibility. Thanks @Anheledir

stream button

Bug fixes and web design improvement


  • Several other bugs have been fixed and the WEB design has been improvement.
  • On the camera website, there is a change in the name of the tabs from
    • Camera Configuration -> Camera
    • Wi-Fi Configuration -> Wi-Fi
  • Improvment camera flash functionality

1.0.2 Firmware for ESP32-cam

Summary


  • Fixed bug with RAM allocation.
  • Fixed bug with video stream
  • Added another WiFi network configuration
  • Added more command for camera configuration from serial console
  • Changes in the method of sending photos
  • Used mDNS record as camera name in the Prusa Connect
  • Bug fixes

This is a stable version for the ESP32-cam

Fixed bug with RAM allocation


Version of the firmware 1.0.1 had an issue with RAM memory allocation. So in this FW version, the WEB server on the camera had to be turned off, and then turned on again after sending the image to Prusa Connect. Concurrently, the stability and speed of the firmware were improved.

Fixed bug with video stream


The previous error also caused the video stream to malfunction. Currently, the video stream work at the address http://IP/stream.mjpg. The number of frames per second (FPS) depends on the quality of the Wi-Fi connection and the image resolution. Lower image resolution results in higher FPS. During an open video stream, the web server and all other camera functionalities remain operational.

From my testing, I found that at the maximum resolution of 1600x1200, I achieved approximately 3 FPS. However, at a resolution of 1024x768, I attained approximately 6-7 FPS.

Added another WiFi network configuration


In the Wi-Fi settings tab, under Advanced Wi-Fi settings, additional advanced Wi-Fi configuration options have been added.

Now, an option to turn off the service AP upon ESP32-CAM startup is available. After resetting the ESP32-CAM configuration to factory settings, the service AP is automatically enabled.

Additionally, a feature enabling the use of a static IP address for the camera on the Wi-Fi network to which the camera connects has been implemented.

The first step involves setting the IP addresses, followed by switching the setting from DHCP to a static IP address, and finally restarting the MCU.

It is necessary to clear the cache in the browser for the changes to take effect. The cache interval is set to 24 hours, meaning it is automatically deleted after 24 hours.

Added more command for camera configuration from serial console


Several additional parameters have been added for configuring the camera via the serial interface.

Changes in the method of sending photos

The previous method of sending photos caused incomplete photo transmission to Connect. The new method should resolve this issue.

Used mDNS record as camera name in the Prusa Connect

The camera name that was displayed in Prusa Connect was a static value. Currently, the mDNS record is used as the camera name.

Bug fixes


Several other errors were fixed. Additional logging was added, for better analysis. Thanks @Anheledir and @JimBim89 for the bug fix
