| Re: [cf-dev] How to get observe response as variable |
|
Hi, sorry, I missed to answer in time. // “This is where i want to Access content variable” The question will be, which version of the “content”?
Notifications are intended to change the content over time, therefore the example uses a “CoapHandler”, which get’s called, when your client receives a notification
of such a content change. How would you reflect that using a “variable”? One solution maybe to use a “queue” (of content), so push the received content in onLoad to the queue, and pop it, where you want to receive the content. But though
I don’t know, what you want to do there, what you can’t do in the onLoad callback of the CoapHandler. Mit freundlichen Grüßen / Best regards

On Behalf Of Sedat Bilgili Hello, Currently i am trying to get some observe data from my CoAP server nodes. I am using the code in CoapClientExample.java “\demo-apps\api-demo\src\org\eclipse\californium\examples\”. It Works perfectly and prints values
on screen. However i want to access content variable. ************************************* CoapObserveRelation relation = client.observe( new CoapHandler() { @Override public void onLoad(CoapResponse response) { String content = response.getResponseText(); System.out.println("NOTIFICATION: " + content); } @Override public void onError() { System.err.println("OBSERVING FAILED (press enter to exit)"); } }); // “This is where i want to Access content variable” // i.e. : System.out.println(content); ************************************* I have little experience with java. There’s no global variables or pointers like C/C++. How can i make it work ? Thank you, Sedat Bilgili. |
