X_LINK_ERROR

We suddenly got an error message from OAKD camera,

RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'rgb' (X_LINK_ERROR)'

After reboot the camera, all goes well.

Question: What does it mean for the above error?

What could cause the error?

Is it coding?

What should we handle this error grammatically?

Hey,

This kind of error usually points to a power issue. Make sure you're using a USB 3.0 cable and port (not USB 2), and if you're running it on something like a Raspberry Pi or Jetson, try powering the camera with an external power supply

Best,

I am using POE camera. not usb. Can you update your answer with the new information? Thanks. @lovro

Hi, thanks for the update!

This kind of error on PoE happens if the Ethernet cable is very long (over 15m), the PoE power isn’t stable, the pipeline is too heavy, or the device is overheating. If it happens again, try checking the cable and power source, reducing the pipeline load or monitoring temperature/resources using this.

Best,

Thanks for your reply. Somehow we don't see the problem any more. Thanks again.
