17 As the CoAP client doesn't create socket it is using, the application is responsible for creating
23 The following is an example of a CoAP client initialization and request sending:
45 Before any requests can be sent, the CoAP client needs to be initialized.
46 After initialization, the application can send a CoAP request and wait for the response.
47 Currently only one request can be sent for a single CoAP client at a time. There can be multiple

13 Zephyr comes with a batteries-included CoAP server, which uses services to listen for CoAP
14 requests. The CoAP services handle communication over sockets and pass requests to registered
15 CoAP resources.
20 Some configuration is required to make sure services can be started using the CoAP server. The
64 Services defined with the ``COAP_SERVICE_AUTOSTART`` flag will be started together with the CoAP
71 The following is an example of a CoAP resource registered with our service:
114 /* Return a CoAP response code as a shortcut for an empty ACK message */
127 As demonstrated in the example above, a CoAP resource handler can return response codes to let
