CoAP in OpenThread

[KOUDA MOHAMED AMINE]

hello , is there any one who worked on openthread's coap because i need a simple coap example (server + client) 

 

[KOUDA MOHAMED AMINE]

no one !!!??????

OpenThread provides CoAP Client and Server functionality to the application via the public CoAP APIs in include/openthread-coap.h.  Note that OpenThread's CoAP API is disabled by default.  To enable that feature, you will need to add `--enable-application-coap` to the `./configure` options.  Unfortunately, OpenThread does not yet have a simple example that demonstrates using the OpenThread public CoAP APIs.  Until then, you can look throughout the OpenThread code and see many examples of how CoAP is used internally.

I have the same request, and I don’t know exactly how to start…

Request :

I want to send a Coap request from a device A (for instance the Leader) to a device B (for instance a Router) and I want the device B being able to get a response back to A.
The request could be to retrieve the temperature value on device B and then display it back to device A.

 

One approach could be to create a new class similar to  NetworkDiagnostic for example named NetworkAppli and use somehow the same architecture/code as what is found inside the NetworkDiagnostic class.

 

It is the good approach ?

 

Of course I don't want to patch the OpenThread code...

Thank you very much

Code external to the core OpenThread library should use OpenThread's public API.  OpenThread exposes CoAP via the CoAP API.  Note that to enable this function, you must specify `--enable-application-coap=yes` as part of `./configure`.

Hi,

I confirm :). If you would like to try Nordic Semiconductor's platform we provide nRF5 Software Development Kit for Thread based on OpenThread stack. Among others it includes CoAP examples:

"The Thread MTD CoAP Client, Thread Simple CoAP Client, and Thread Simple CoAP Server examples demonstrate interactions between nodes performing different Thread roles with the use of OpenThread and built-in CoAP protocol. Thread Simple CoAP Client and Thread Simple CoAP Server examples demonstrate Full Thread Device functionality (Thread Router role and REED role). Thread MTD CoAP Client example demonstrates Minimal Thread Device functionality (Minimal End Device role and Sleepy End Device role)."

Look here for more info: https://groups.google.com/forum/#!topic/openthread-users/Twiyp0Ec-jk 

Best regards,

Krzysztof Loska
