The Problem

I was playing with the device for a month but struggling with taking good pictures due to the issue with no possibility to change built-in LED intensity.

hw: ESP32-CAM-MB + OV2640 camera
fw: latest stable 15.7.0
The device is assembled on my water meter outside my home, underground, i do not have direct/easy access to it.

Today I've made an OTA update

At first i've used the AI-on-the-edge-device__remote-setup__v16.0.0-RC5.zip
It appeared to update only UI to 16.0.0-RC5, and the fw was still 15.7.0
In this case i've observed the issue with build-in LED flash was ON only for the first time, and then it was always OFF until next reboot. It wasn't working also when I tried Data->LiveStream (Led ON)
Then i used the: AI-on-the-edge-device_update_v16.0.0-RC5
and after restart it shows a critical error 0x4, which is Cam bad

The info tab shows the current fw an UI is updated to 16.0.0-RC5
After revert via OTA using AI-on-the-edge-device_update_v15.7.0 it works exactly as it was previously with 15.7.0.

I've reproduced it 2 times using above steps.

Version

16.0.0-RC5

Try a power off for a couple of seconds.
Not a reboot. Reboot does not work.

I've just tried the same using OTA update to RC4 and RC1 and also have 0x4 Cam bad critical error.
After downgrade to 15.7.0 camera works fine, but build-in LED flash intensity regulation does not have any effect.

This was not possible for me on 15.7.0. No matter if it's set to defoult 50, 10 or 100 the picture looks very similar.

Thank you very much for the help.

please try this version: https://github.com/jomjol/AI-on-the-edge-device/actions/runs/12610459770
https://github.com/jomjol/AI-on-the-edge-device/actions/runs/12610459770/artifacts/2385741602
In the previous version, ".jpeg_quality = 6, // 0-63 lower number means higher quality", this can lead to problems when initializing for cameras with poor quality. I changed the value to 12.
