Erbium (Er) REST Engine and CoAP for Contiki

Erbium (Er) is a low-power REST Engine for Contiki that was developed together with SICS (and a rare earth element that is found in the Ytterby mine near Stockholm). The REST Engine includes a comprehensive embedded CoAP implementation, which became the official one for the Contiki OS. It supports draft-ietf-core-coap-03 and draft-ietf-core-coap-08, together with blockwise transfers and observing.

Our CoAP C implementation was successfully tested at the ETSI IoT CoAP Plugtest in Paris, France, March 2012. It passed all mandatory and optional tests with all the other implementations that supported them. Erbium is also used to implement the IPSO Profile and tested at the IPSO Interop Event in Paris, France, April 2012.
