About libcoap
|
|
=============
|
|
|
|
libcoap is a C implementation of a lightweight application-protocol
|
|
for devices that are constrained their resources such as computing
|
|
power, RF range, memory, bandwidth, or network packet sizes. This
|
|
protocol, CoAP, is standardized by the IETF as RFC 7252. For further
|
|
information related to CoAP, see <http://coap.technology>.
