Thanks, Joakim. I have created a similar example, although it's not in
the repository examples collection. For anyone interested, check out
the, "gcoap presentation" thread on the ML from last October [1]. It
references the data collection application as well as a presentation and
video I created about it.

I think an example with an observable, periodic resource would be a
useful addition to the example collection. The periodic resource could
be simply sending the xtimer_now value or adc_read or similar
periodically every 5 seconds or something to show how to set up
periodic notifications in gcoap.
Without looking at the code I guess it would be driven by xtimer to
provide events to the gcoap observable resource event loop.
Best regards, Joakim

Hi all,
Recently I received private mail with some specific questions
about gcoap and DTLS. Responses below.
There is a work-in-progress pull request for integration of DTLS
and gcoap, #7177. There is good discussion in there about the best
way to integrate DTLS generically with RIOT's sock networking.
RIOT's master branch includes support for the Observe extension
for non-confirmable messaging. There is an open PR for integration
with confirmable messaging, #7548.
There also was a question about "periodic resources", but that's
not part of the CoAP spec AFAIK. Certainly one could integrate a
timer to periodically send Observe notifications.
