Complete CoAP Implementation in C.
Despite designed for embedded systems (e.g. ARM Cortex-M0/M3, AVR, ESP8266) it can be used on nearly every system that has c-lang support.

* Royalty-free CoAP stack
* complete request/response logic
* unified Client & Server
* easy to use
* small memory footprint
* using C99 stdlib, suitable for embedded projects
* detached packet receive/send logic
* Arduino support (experimental)

There is also a working OpenSource **client lib available in GoLang** @ https://github.com/lobaro/coap-go

# Future development
We use the stack internally at lobaro to build universal gateway / sensor systems for our customers. Additions will be constantly merged into this repository.
