| Re: [cf-dev] Restore an observe relation after restart |
Hi Eugene,
OK. I would like to discuss it in an issue.
There is some to define in the wording, e.g. server and client, and coap-server and coap-client. Because, if you restart the server, you restart the coap-client of your observes. There is some kind of support for that, because leshan requires that as well. But it’s currently not “out of the box”.
The easier solution is, just to reestablish a new observation, when you server (coap-client) restarts.
Mit freundlichen Grüßen / Best regards

Subject: Re: [cf-dev] Restore an observe relation after restart
Hi Achim,
not sure, perhaps not.
My case is:
- an embedded device connects to a Californium server.
- server sets up an observe relation
- embedded device sends notification when has data
- I restart a Californium server due to redeploy and
new instance of Californium does not know about that relation since they were stored in-memory
so responds with RST.
I'd like to restore that observe relation somehow.
Or at least catch that unknown Observe notification.
Thanks,
Eugene Nikolaev
BTW what is preferred for such questions: this mailing list or creating a github issue?

Hi Eugene,
Depends on your exact setup. Could you check
https://github.com/eclipse/californium/issues/472
if this applies to your case as well?
