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

Follow [Lobaro on Twitter](https://twitter.com/LobaroHH) to get latest news about iot projects using our CoAP implementation!

# Getting started

Read the [Porting Guide](./PortingGuide.md) for information on how to port the library to your framework.

# Demo/Example

# 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.
