CoAP utils
The CoAP utils library is a simple module that enables communication with devices that support the CoAP protocol. It allows sending and receiving non-confirmable CoAP requests.
Overview
The library uses CoAP and BSD socket API.
After calling coap_init(), the library opens a socket for receiving UDP packets for IPv4 or IPv6 connections, depending on the ip_family parameter.
At this point, you can start sending CoAP non-confirmable requests, to which you will receive answers depending on the server configuration.
Limitations
Currently, the library only supports the User Datagram Protocol (UDP) protocol.
Configuration
To enable the CoAP utils library, set the CONFIG_COAP and CONFIG_COAP_UTILS Kconfig options.
