The CoAP module provides a simple implementation according to [CoAP](http://tools.ietf.org/html/rfc7252) protocol.
The basic endpoint server part is based on [microcoap](https://github.com/1248/microcoap), and many other code reference [libcoap](https://github.com/obgm/libcoap).
This Module implement both Client and Server side. GET/PUT/POST/DELETE is partially supported by Client. Server can regist Lua function and varibles. No Observe or Discover supported right now.
