Error: XLINK_READ_REL_RESP

mzbt

Hello, I encountered the following Error while running the OAK camera after a long period:

F: [global] [ 462796] [Scheduler00Thr] dispatcherResponseServe:928 no request for this response: XLINK_READ_REL_RESP 1

Is there any way to catch this exception (I use Python API) ? Any ideas would be greatly appreciated. Thanks!

Hi @mzbt
There is no way to catch this other than to put the whole execution in a try..catch block.
We currently don't expose the specific errors.

Thanks,

I have seen that today as well (with a rather recent firmware blob)

So, this time around, it was only running for 5 minutes:-( But that's one of the shorter runs:-( After that, my ROS node does not produce any topic messages any longer:-(

Can you give us a MRE we can test locally? cc @DaniloPejovic can we test this as well?

Thanks

MRE? Sorry;-) I'm using coneslayer_openvino_2022.1_6shave.blob & coneslayer.json from mkrupczak3/Coneslayer inside a ROS2/Humble node on a RasPi5 with Ubuntu 22.04;-)

OK, I pushed my sources to mw46d/ros_coneslayer , I hope, that helps a bit.

Today it lasted for almost 13 minutes;-) on a stationary rover, so the cables don't move or anything;-) I'll probably have to create a 'node restarter' for now.

Thanks for looking into it;-)
