I will delete that repository as capturing 3 frames, going to lightsleep, waking-up on trigger and taking 1 frame is flawed. The time to take that one last frame can be up to 1-2 seconds, which can be more than the original 500ms + 160ms.

Interested in really fast captures with good exposure and colour-balance? I have posted my modifications to this tutorial on GitHub:

Thanks to Rui and Sara for their help.

In reply to Dave.

Because the plugin is to upload files manually to the board, which is not done in this tutorial.
It saves the files to the filesystem via code.

In reply to Sara Santos. When I first tried this program I never had a problem. Coming back to it recently I started getting the errors I mentioned. I will try again. Just for my information why don't you need the LittleFS plugin?

Hi.
Is everything working as expected now?
For this particular tutorial, you dont need to install the LittleFs plugin.

Hi Sara,

Please remove my last two comments. I realise now that there is ESP Mail Client and an older one called ESP32 Mail Client. My problem could be that I still haven’t got LittleFS installed properly on my Linux machine.

Thanks,
Dave

Looks like I don’t how to drive the Arduino IDE. I checked for the installed version of ESP Mail Client and was told it was NOT installed. So,I installed version 2.1.6 because I could not see 3.4.24 The program now compiles.

Hi Sara,

I don’t see LittleFS being included in this file:

https://raw.githubusercontent.com/RuiSantosdotme/ESP32-CAM-eBook/master/Code/Module_3/Send_Photos_Email_NEW/Send_Photos_Email_NEW.ino

ESP core version 3.3.0
Arduino ESP version 2.0.18-arduino-5
ESP Mail Client 3.4.24

Thanks,
Dave

Hi.
No, you don’t need to create a directory.
And those lines should already be included in the library we’re using.
Unless the author has made some breaking changes meanwhile.

Which version of the library are you using?
And about the ESP32 core version? What’s the version you have installed in arduino IDE?

Regards
Sara
