Pulls in both tinyDTLS and Contiki as git submodules to make maintenance easy (possible).
Make sure the submodules are updated:
git submodule update --init
setup tinyDTLS
./setup.sh
Make the tinyDTLS example:
cd ./tinydtls
make TARGET=redbee-econotag
That should make a dtls-client_redbee-econotag.bin
That's all for now :)
