Re: [riot-users] gcoap and DTLS

2018-04-16 Thread Cristina Paniagua 
Hi,

There is a service in IPv4 that it's used to register any device or system, not 
only the ones that are used RIOT. it's already developed in IPv4 ( A server at 
one computer). I have to find a way to register my own device and interact with 
it. Maybe I can use your solution, I've never tried before.


Thank you, Cristina.

Hi Cristina,

I cannot help with the IPv4 code fragments, but I wonder why you want to
use IPv4 on RIOT?

To gain 'transparent' IPv4 connectivity, you can use IPv6-embedded IPv4
addresses and perform stateless address translation at a gateway.

Would that help?

Best,
  Thomas

Re: [riot-users] gcoap and DTLS

2018-04-16 Thread Koen Zandberg 
Hi Cristina,

To expand a bit on Thomas suggestion, I have good experience with
Tayga[1] at a gateway and using this to provide connectivity to the IPv4
part of the internet from IPv6 only hosts. For guides on setting this up
I would suggest looking for generic guides on NAT64 for IPv6 only
networks, similar to the setup described in rfc6586[2]. While the
situation there is more aimed at regular wired networks, from a network
perspective, it seems similar to your requirements.

addition to the example collection. The periodic resource could be simply
sending the xtimer_now value or adc_read or similar periodically every 5
