Example of libcoap running in Zephyr
====================================
The Zephyr project environment needs to be pre-installed. By default, the
libcoap Makefile assumes that this is located at ~/zephyrproject .
To build the coap-client example, do
$ make
The executable gets built in ~/zephyrproject/zephyr/build/zephyr/zephyr.exe
which is then copied to coap-client .
For using the native_sim board using Linux, you may need to do something like
the following (ens32 is the external interface name)
$ sudo iptables -t nat -A POSTROUTING -o ens32 -j MASQUERADE
$ sudo sysctl -w net.ipv4.conf.all.forwarding=1
so that ./coap-client is able to get out onto the internet.
