Communication exception

Hi,

Camera: OAK-1 POE
I am using a simple script just to show images without any neural network. just the image node to get the image at maximum resolution 3840x3040. After 8-10 hours I keep getting this error:
communication exception - possible device error/misconfiguration. original message 'couldn't read data from stream 'rgb' x_link_error'

What is the cause of this error ?

Thank you very much

Hi martin181818
What's the FPS you are set to? I'm thinking it could be a bandwidth issue, since you are sending max res frames (3840x30408 1FPS = 93388800b/s).

Thoughts?

Thank you for your reply.
The FPS value I am using is 30 FPS.

That's too much. The pipeline likely blocks on the Xlink nodes. Try lowering the FPS to eg. 5FPS and see if it makes a difference.

Thanks,
