how to get the data on server side in mesh

[ps_anu]

hi ...

I am working on mesh 3.1 version . I have used light switch example . In this case , i am sending the character in generic_onoff_set_cb , and changed from bool to character on client side . Now what are the change on server side , in order  to get the character from client to server . on server side i need to get the same data . 

Thanks

Hi,

I noticed that you already created a ticket with the same question: https://devzone.nordicsemi.com/f/nordic-q-a/53053/how-to-send-string-from-client-to-particular-server-in-mesh

Have you taken a look at the thread that Joakim suggested? 

I would also suggest you to continue in that thread instead of creating multiple threads about same question.

You shouldn't need to change anything on the server side to receive the message from the client.

Have a look at this callback on the server: mesh_evt_cb. Whenever the NRF_MESH_EVT_MESSAGE_RECEIVED event occurs, the mesh_msg_handle() function gets called. This function, which is defined in access.c, handles all incoming mesh messages on the server side.

hi

mttrinh i am using mesh 3.1 version sdk . i have done somechanges please check here, correct me if i am wrong.

static void button_event_handler(uint32_t button_number)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Button %u pressed\n", button_number);

    uint32_t status = NRF_SUCCESS;
    generic_onoff_set_params_t set_params;
    model_transition_t transition_params;
    static uint8_t tid = 0;

    /* Button 1: On, Button 2: Off, Client[0]
     * Button 2: On, Button 3: Off, Client[1]
     */

    switch(button_number)
    {
        case 0:
        case 2:
            set_params.on_off = 32;
            break;

        case 1:
        case 3:
            set_params.on_off = 8;
            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", set_params.on_off);

    switch (button_number)
    {
        case 0:
        case 1:
            /* Demonstrate acknowledged transaction, using 1st client model instance */
            /* In this examples, users will not be blocked if the model is busy */
            (void)access_model_reliable_cancel(m_clients[0].model_handle);
            status = generic_onoff_client_set(&m_clients[0], &set_params, &transition_params);
            hal_led_pin_set(BSP_LED_0, set_params.on_off);
            break;

        case 2:
        case 3:
            /* Demonstrate un-acknowledged transaction, using 2nd client model instance */
            status = generic_onoff_client_set_unack(&m_clients[1], &set_params,
                                                    &transition_params, APP_UNACK_MSG_REPEAT_COUNT);
            hal_led_pin_set(BSP_LED_1, set_params.on_off);
            break;
    }

then generic_onoff_common.h file changed the bool to uint8_t and generic_onoff_client.c  file modified the  message_set_packet_create 

p_set->on_off = p_params->on_off ;
p_set->tid = p_params->tid; 

thats all . it is correct or wrong ?

explanation for above , i want to sent the integer from client to server when i press the button the respective integer has to go . 

 

Thanks

The code seems ok.

how to pass 150 bytes from client to server for the latest version ..

[ps_anu]

Hi,

My mistake, you would need to make some changes on the server side too, to be able to send string/integer to the server. Did you have a look at the links that Joakim mentioned in your other case?

It included a custom simple_message model example that will let you send a string over the mesh network. It is made for Mesh SDK v1.0.0 but I suggest you to use the example application as a reference/guidance on how you can make a custom model for Mesh SDK 3.1.0, that let you send a string/integer.

Here is documentation on how to create a model.

Also have a look at this, it might be of help.
