Hi,

I use example projects  Thread: CoAP Client and  Thread: CoAP Server . I can send and receive data over CoAP. My purpose is to use CoAP, CoAPS and UDP tohether. If client send UDP message, server can reply with UDP payload or client send CoAPs, server reply same manner. How can I accomplish to send CoAPs and UDP data?

Hi,

Support for CoAP, CoAPS, and UDP is all part of the prebuilt OpenThread libraries.

You can find the API reference in our infocenter:

• CoAP
• CoAP Secure
• UDP

All these APIs can be used in the application by including the corresponding header file, e.g:

• #include <openthread/coap.h>
• #include <openthread/coaps.h>
• #include <openthread/udp.h>

You can have a look at the use of the CoAP API usage in "examples\thread\app_utils\thread_coap_utils.c / thread_coap_utils.h"

Best regards,
Jørgen

Hi,

UDP is implemented in the CLI example. You can have a look at the implementation in OpenThread to see how received messages are parsed.
