Hi all,

I've tried to add another 2 attributes to the "coap_endpoint_t" structure :

typedef struct
> {
>     coap_method_t method;
>     coap_endpoint_func handler;
>     const coap_endpoint_path_t *path;
>     const char *core_attr;
>     const char *if_attr;    // Interface attribute
>     //const char *title;

> } coap_endpoint_t;

Obviously i added the related attributes also in the coap.c file, into the

Now when i call the */.well-known/core* resource, the response is as
follows  :


And that is what i want, but now, when i perform a GET request onto the
other resource */board_GET_SAMR21* the payload is EMPTY, where the right
response should be a JSON string.

So, there is something that i forgot to modify, as packet length or
something similar?

Thanks all as always!
*best regards, *
