Lobaro-CoAP

Build Status Gitter Chat

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. Also we plan a big redesign until the end of 2017. With this update (which is ongoing already) we include many learnings from our other project.
