how to print the data from particular node to uart

[ps_anu]

hi...

i am working on mesh , i have done light switch example , now i want to get some message from node and send to particular node . how to print the same message which is from particular node to uart termite 

please help me out. 

thanks in advance

Which part are you stuck on:

1. Identifying which node sent a particular message?
2. How to print to the UART?

Each one is entirely independent of the other.

i am using two boards , example A and B .. A will sent a message to B And that message has to be read and write on uart using termite

So, again, have you checked your data types?

[ps_anu]

how would you say that set_params.on_off is pointer?

I didn't say that it was - I said that the way you are using it requires that it is!

Aha - I found what I actually said:

https://devzone.nordicsemi.com/f/nordic-q-a/44964/how-to-print-the-data-from-particular-node-to-uart/179179#179179

As I said, arr[] and Ara[] are char arrays, so this assignment:

set_params.on_off = arr;

expects that set_params.on_off is a char pointer.

If set_params.on_off is not, in fact,  a char pointer - then that code is not going to do what you want!

Again, this is standard 'C' programming - nothing specifically to do with Nordic:

The thing on the left-hand side of an assignment has to be of the same type (or a "compatible" type) as the thing on the right-hand side of the assignment.

Thanks alot both of you . i have changed in client  side (set_params.on_off) , now what are the things i should change in server side

One of the reasons this thread is getting so long and so hard to follow is that you keep giving these over-brief, vague posts thin on detail - so that we keep having to pull the information out of you!

You still haven't answered all the questions about the problems you were seeing.

So what, exactly, have you changed?

How, exactly, did you change it?

How, exactly, has that changed the behaviour that you are seeing?

Is that now the behaviour that you expect/require?

Did you understand the point (sic!) about pointers ?

[ps_anu]

yeah , set_params.on_off is in bool state , so now i changed it to a character,

 uint16_t x_in;
    char a = 78;
 //char arr[80] = "code";
// char ara [80] = "set";
 
    switch(button_number)
    {
        case 0:
        case 2:
        
           x_in = a;
            break;

        case 1:
        case 3:
       
            x_in = a;
            break;
    }

    set_params.tid = tid++;
    transition_params.delay_ms = APP_CONFIG_ONOFF_DELAY_MS;
    transition_params.transition_time_ms = APP_CONFIG_ONOFF_TRANSITION_TIME_MS;
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Sending msg: ONOFF SET %d\n",x_in);

yes i got  result , but not in server side, i hope that i  need to make some changes in server side, where i should change and how

Then it's still wrong!

apparently not!
