Enable server-client role in a single node.

[Bhumika]

Hi,

In nRF_SDK_for_Thread_and_zigbee, we were using the following function to enable thread coap in both server and client role in a single node:

/**@brief Function for initializing the Constrained Application Protocol Module.
 */
static void thread_coap_init(void)
{
    thread_coap_utils_configuration_t thread_coap_configuration =
    {
        .coap_server_enabled               = true,
        .coap_client_enabled               = true,
        .configurable_led_blinking_enabled = false,
    };

    thread_coap_utils_init(&thread_coap_configuration);
}

I want to implement the same in nRF_Connect_sdk.
What should I do to enable both server and client roles in a single node in nRF_Connect_SDK?

Hi Bhumika

In the nRF Connect SDK, we have some Thread samples. Among these are a CoAP Server and CoAP Client sample.

From the CoAP Server docs:
"This sample uses the native OpenThread CoAP API for communication. For new application development, use Zephyr’s CoAP API. For example usage of the Zephyr CoAp API, see the Thread: CoAP Client sample."

So I recommend to start with the Thread CoAP Client and add code for the CoAP Server yourself from the Zephyr CoAP API.
Do not mix code from the two examples, as they use different APIs.

The Zephyr CoAP Server sample might give you some pointers on how to set up a server using the Zephyr CoAP API.

The Thread additional configuration options might also be useful.
