When i plug a i2c device (arduino nano) on i2c bus the camera stops with message:

[E][camera.c:1049] camera_probe(): Detected camera not supported.
[E][camera.c:1249] esp_camera_init(): Camera probe failed with error 0x20004

How can i use a arduino project with camera and i2c devices?

Solved! Maybe the esp_camera use some kind of scan and my arduino device was receiving those scan data.

i've received some strange bytes on my arduino board after camera setup.
So i've added a delay on arduino before start the i2c slave (addr 22), restarted the esp32 device and the camera worked fine.
Finally i removed the delay and changed my slave addr to 99 and everything worked fine
