Constrained Application Protocol

Lab ready Full lab

REST-like protocol for constrained devices, typically over UDP, with confirmable/non-confirmable messages, tokens, and resource discovery. Observe provides lightweight pub/sub; Block-wise transfers move large payloads. DTLS and OSCORE are common security layers on 6LoWPAN and Thread networks.
