For embedded applications that can call the 'main()' function multiple times, they need to have any statically (globally) defined variables reset to their default values.
Example of libcoap running on RIOT
==================================
To build the examples, do
$ make
This will
* download RIOT from the upstream git sources
* update the RIOT environment with pkg/libcoap, examples/libcoap-client
and examples/libcoap-server taken from pkg_libcoap/, examples_client/
and examples_server respectively/.
(updates RIOT's libcoap code to the latest commited version in your
environment).
* build the client application
* build the server application
To run (and/or rebuild) the server application
* cd RIOT/examples-libcoap-server
* make RIOT_CI_BUILD=1
* make term
* (at the shell prompt) coaps start
The server creates a resource for 'time' with a query 'ticks'. This is
reported for `.well-known/core`. The work flow for adding more resources does
not differ from regular libcoap usage.
To run (and/or rebuild) the client application
* cd RIOT/examples-libcoap-client
* make RIOT_CI_BUILD=1
* make term
* (at the shell prompt) coapc
The client will try to connect to the URI defined in app.config named
CONFIG_LIBCOAP_CLIENT_URI (unless overridden by running 'make menuconfig').
Note to developers
==================
PKG_VERSION= in pkg_libcoap/Makefile needs updating if you need a different
version of libcoap to get initially installed into RIOT/pkg/libcoap.
Kconfig support is available. Running make in the libcoap distribution
examples/riot directory will try to add in a 'rsource "libcoap/Kconfig"'
entry into RIOT/pkg/Kconfig
