libcoap client example

This example shows how to configure a client to use libcoap

Fast configuration (Between RIOT instances):

Preparing the logical interfaces:

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

Client invocation

For the client:

PORT=tap0 make term
coapc

The IP address to connect to needs to be that as returned by libcoap_server, or that of the tap0 interface, etc.

Handling the static memory allocation

libcoap for RIOT is using the sys/memarray module and therefore there are certain limits. Said resources are defined in libcoap/src/coap_mem.c, but can be overwritten at compile time.
