12 libcoap is a C implementation of a lightweight application-protocol for
13 devices that are constrained by their resources such as computing
14 power, RF range, memory, bandwidth, or network packet sizes. This
15 protocol, CoAP, is standardized by the IETF as RFC7252. For further
16 information related to CoAP, see http://coap.technology.
