CoAP over 6LoWPAN Introduction

Page Summary

This page is an introduction to the „Constrained Application Protocol“ (CoAP). Lobaro hardware implements this protocol to interact wirelessly with external CoAP Clients over IPv6 in a standardized way.

The target audience is system integrators which want to embed Lobaro sensor solutions into their (existing) systems and networks without doing any electrical engineering work or low-level embedded programming.

Quick Facts

  • CoAP ≈ lightweight HTTP
  • URI and content-type support
  • Very low overhead (binary data)
  • Easy cooperation with HTTP (e.g. Proxies)
  • Fully Standardized by RFC7252
  • Many free implementations (C#,Go, Java…)
  • Designed for building automation & M2M
  • Reliable transmission over UDP
