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.

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

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,

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.
