Problems with OAK-D SR PoE

Brais

I have a Luxonis Camera connected by a PoE cable to a switch which is connected to my laptop. I'm using the OAK Viewer 1.6.3 and 75% of times the laptop and program recognise the camera but it does not connect to it. Is this a common problem by the software or maybe is a hardware/connection/cables issue?

Hey Brais - this is not expected behavior. If OAK Viewer can see the camera but only connects some of the time, that usually points more to PoE/network setup or marginal power/link stability. Discovery and connection are separate stages, so it is possible for the viewer to list the device and still fail when opening the actual session.
Do you have everything updated to the latest version? Is behaviour the same if using DepthAi without OAK Viewer?

We have debugging steps written out here, you can folow:

I think I have everything to the latest version. When I try to use the camera with the DepthAI, sometimes there's a disconnection but it connects rigth away. That I think it's I move the cables a little but with the OakViewer it's like taking the lottery. Very few times works how it's supposed to, it detects de camera, says that it's connected but I can't open a pipeline.

Brais - if moving the cable causes disconnections in DepthAI too, this points more to a cable / PoE / network stability issue than just OAK Viewer. A stable setup should not drop connection from small cable movement.

Since OAK Viewer detects the camera but often cannot open a pipeline, there may also be a viewer-side issue. I’d first try another Ethernet cable and, if possible, another PoE port/switch. If DepthAI works reliably after that but OAK Viewer still fails, then it is more likely an OAK Viewer issue.

Trying to connect today the oak viewer gave me this error:
Sufficient number of message was not received from the queue until the timeout of 15s.
Required: 3, Received: 0. Pipeline configuration is not usable.
The issue is caused by DepthAI.
If the configuration should be valid, please report the issue. Provided configuration cannot be applied. No previous configuration to revert to was found. Pipeline was stopped.

Brais - This error means OAK Viewer started the pipeline, but no messages arrived from the device within 15 seconds, so the pipeline was stopped. Given the earlier cable-related disconnects, this still points more to a connection / PoE / hardware stability issue than to a valid pipeline problem. Did you try different Ethernet cable and, if possible, a different PoE port/switch/injector?

Brais

I tried with 3 different ones. When I execute the camera with scripts and API it all goes smoothly so i lean towards an oak viewer issue, but i don't know what is causing it.

Hey Brais, sorry for the confusion. I initially thought your device was the OAK-D Short Range, but I now see it’s the OAK-D ToF. It was actually renamed from OAK-D-SR-PoE to help avoid exactly this kind of mix-up.

At the moment, OAK-D ToF (OAK-D-SR-PoE) is not yet supported in OAK Viewer. Support is currently in development and should be available soon.

Sorry again for the misunderstanding.

Thanks,
Oskar

Then thanks for the help.

Brais - happy to help and sorry for confusion!
