ABOUT LIBCOAP
11+
=============
12+
13+
libcoap is a C implementation of a lightweight application-protocol
14+
for devices that are constrained their resources such as computing
15+
power, RF range, memory, bandwidth, or network packet sizes. This
16+
protocol, CoAP, is standardized by the IETF as RFC 7252. For further
17+
information related to CoAP, see <http://coap.technology>.
18+
19+
You might want to check out
20+
[libcoap-minimal](https://github.com/obgm/libcoap-minimal) for usage
21+
examples.

41+
* RFC7390: Group Communication for the Constrained Application Protocol (CoAP)
42+
43+
* RFC7641: Observing Resources in the Constrained Application Protocol (CoAP)
44+
45+
* RFC7959: Block-Wise Transfers in the Constrained Application Protocol (CoAP)
46+
47+
* RFC7967: Constrained Application Protocol (CoAP) Option for No Server Response
48+
49+
* RFC8132: PATCH and FETCH Methods for the Constrained Application Protocol (CoAP)
50+
51+
* RFC8323: CoAP (Constrained Application Protocol) over TCP, TLS, and WebSockets
52+
[No WebSockets support]
53+
54+
* RFC8516: "Too Many Requests" Response Code for the Constrained Application Protocol
55+
56+
* RFC8768: Constrained Application Protocol (CoAP) Hop-Limit Option
57+
58+
* RFC9175: CoAP: Echo, Request-Tag, and Token Processing
59+
60+
There is (D)TLS support for the following libraries
61+
62+
* OpenSSL (Minimum version 1.1.0) [PKI, PSK and PKCS11]
63+
64+
* GnuTLS (Minimum version 3.3.0) [PKI, PSK, RPK(3.6.6+) and PKCS11]
65+
66+
* Mbed TLS (Minimum version 2.7.10) [PKI and PSK]
67+
68+
* TinyDTLS [PSK and RPK] [DTLS Only]
69+

The examples directory contain a CoAP client, CoAP Resource Directory server
71+
and a CoAP server to demonstrate the use of this library.
