Fork of IoTKit_CoAP by mc-b

Constrained Application Protocol (Coap) ist ein Software-Protokoll welches für Internet der Dinge Geräte zugeschnitten ist.

COAP ist auf den meisten Geräten, die UDP Unterstützen, lauffähig.

Ein COAP fähiges Gerät publiziert seine Sensoren und Aktoren in einem Resource Directory oder stellt selber ein solches zur Verfügung.

Mittels Resource Discovery können die vorhandenen Sensoren und Aktoren mit ihren Attributen abgefragt werden.
