[riot-users] gcoap and DTLS

Until the date, I've been working with IPv6,gcoap and Mulle devices, but I would like to know if I could send from the device a GET to an IPv4 address.  I read that it's not supported by RIOT, but I found some library IPv4, I tried to use and it's not working.

someone knows more about the use of IPv4 in RIOT?

Thank you all, Cristina.

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.
