DTLS sock async test application

This is a test application for DTLS sock sock_dtls_t with sock_async.

Testing using RIOT native

For testing, we can use two RIOT native RIOT instances. For that first we need to prepare the network interfaces:

$ ./../../dist/tools/tapsetup/tapsetup --create 2

For the server instance:

$ PORT=tap0 make all term
[...]
> dtlss start
ifconfig

For the client:

$ PORT=tap1 make all term
[...]
> dtlsc <server ip address> "DATA to send"

Debug logs

To enable debug logs uncomment CFLAGS += -DCONFIG_DTLS_DEBUG in the Makefile. Tinydtls supports setting the log level. See Makefile for more info.

Configs and constraints

DTLS sock acts as a wrapper for the underlying DTLS stack and as such, the constraints that applies specifically to the stack are also applied here. For tinydtls, please refer to dtls-echo README.
