Yet to implement this Internet protocol on Class 1 devices (i.e., \textasciitilde{} 10 KiB of RAM and \textasciitilde{} 100 KiB of ROM) also lightweight implementation techniques are necessary. This document provides lessons learned from implementing CoAP for tiny, battery- operated networked embedded systems. In particular, it provides guidance on correct implementation of the CoAP specification {[}I-D.ietf-core-coap{]}, memory optimizations, and customized protocol parameters.}, }
