Hi men,

I'm having problems with adding a payload to strings on CoAP. I added the various things, cul coap-server, res-sensor and cc26xx-web-demo and it works. The only thing I would like is a reading of a string and not an int. I followed the example of the ADC, but nothing. What can I put in place of the CC26XX-WEB-DEMO-CONVERTED-LEN? From how I understand this you need to convert an int, but how can I see a string? My string is simply a printf.

Thanks for your help

Try to refer to how cc26xx-web-demo implements res_ble_advd.

Ok, but I have the value of string in cc26xx-web-demo, How do I re-call the printf?

What do you mean re-call the printf?

I have to generate a personal code for my work into cc26xx-web-demo.c. Now I see the printf string of code into CoAP. How can I call back the printf situated in cc26xx-web-demo.c?

Still couldn't understand what you want to do.

I add a example on cc26xx-web-demo and I want to add the resources with string on CoAP. I following the ADC, but I want string not value number.

Example:

if(strcmp(data, "A") ==0) {
leds_on(LEDS_RED);
data = "LED RED IS OPEN" --> CoAP
}

value = data;

I have told you to refer to how cc26xx-web-demo implements res_ble_advd.

I saw it, but how do I get the printfs located in the cc26xx-web-demo.c?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

Have you studied res_ble_post_put_handler?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Yes, but I did not understand that much

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

The example is already there. I can only suggest you to study hard and play with it to know it thoroughly.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Wanting to do the method instead of get the post, the code is the same?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

Get and Post are different.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

If I want to use the GET, the res-advd how example of following, it's good?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

What is good?

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I'm arrived at this point. How Can I call back the printf situated in cc26xx-web-demo.c?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

I cannot suggest anything just according to those codes.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

could you create a guide on sunblog?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

Why? res_ble_advd in cc26xx-web-demo already shows how to do it.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

But with value different of res_ble_advd.

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

I don’t see difference. res_ble_advd also shows string in COAP resource.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I understood the code, but I do not know how to pass the printfs located in the cc26xx-demo.c

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

Just use a global string variable and extern it.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Ok, but the values in the printfs change according to the state. If I set a variable string, it always gives me the same value.

If for example, I add this code on CoAP : With printf on CoAP the leds is open. It's possible?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

When state changes, you change the global string variable and it should map to COAP resource.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

How define the global string variable?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

Just claim string variable outside function scope and it will be global variable.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

in cc26xx-web-demo.h -> #define STRING for example?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

No, it’s incorrect. This is very fundamental of C program so please read some C bible or google it.

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

Did you intend the "variable conteined into main and call back with extern in another file"?

0 YiKai Chen over 8 years ago in reply to Mark Felberg

Guru 735695 points

Try to refer to www.tutorialspoint.com/.../c_scope_rules.htm

0 Mark Felberg over 8 years ago in reply to YiKai Chen

Guru 19990 points

I declared a variable at the beginning of the cc26xx-web-demo.c and inserted it in:
char abc;

if (strcmp (data, "OPEN") {
data = ((char *) "It's open");
data = abc;
}

Then I take the variable abc and the place of "len" in res-advd?

I am not clear about your descriptions.
