Some troubles in creating groups

Question

I'm trying to create more groups in mesh.We know that all the nodes(servers) are divided into two groups called ODD and EVEN,so I want to create more groups.

I have changed some codes in the provisioner and client.

In the provisioner node_step.c,the changes as follows,

add the NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT3, in config_steps_t,

in the function of config_step_execute(),

}

static void config_step_execute(void)
{
   ......

    switch (*mp_config_step)
    {
      ......

    

        
        case NODE_SETUP_CONFIG_PUBLICATION_ONOFF_SERVER:
        {
            config_publication_state_t pubstate = {0};
            pubstate.element_address = m_current_node_addr;
            pubstate.publish_address.type = NRF_MESH_ADDRESS_TYPE_UNICAST;
            if ((m_current_node_addr % 3) == 1)
            {
                pubstate.publish_address.value = UNPROV_START_ADDRESS + ELEMENT_IDX_ONOFF_CLIENT1;
            }
            else if ((m_current_node_addr % 3) == 2)
            {
                pubstate.publish_address.value = UNPROV_START_ADDRESS + ELEMENT_IDX_ONOFF_CLIENT2;
            }
            else
            {
                pubstate.publish_address.value = UNPROV_START_ADDRESS + ELEMENT_IDX_ONOFF_CLIENT3;            
            }
            ......
        }

        /* Configure subscription address for the On/Off server */
        case NODE_SETUP_CONFIG_SUBSCRIPTION_ONOFF_SERVER:
        {
            __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Adding subscription\n");
            uint16_t element_address = m_current_node_addr;
            nrf_mesh_address_t address = {NRF_MESH_ADDRESS_TYPE_INVALID, 0, NULL};
            address.type = NRF_MESH_ADDRESS_TYPE_GROUP;
            if (m_current_node_addr % 0x03 ==1)//
            {
                address.value  = GROUP_ADDRESS_111;
            }
            else if (m_current_node_addr % 0x03 ==2)
            {
                address.value  = GROUP_ADDRESS_222;
            }
            else
            {
                address.value  = GROUP_ADDRESS_333;
            }
           ......
            
            break;
        }

        case NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT1:
        {
            config_publication_state_t pubstate = {0};
            client_pub_state_set(&pubstate,
                                 m_current_node_addr + ELEMENT_IDX_ONOFF_CLIENT1,
                                 GROUP_ADDRESS_111);
            retry_on_fail(config_client_model_publication_set(&pubstate));

            static const access_status_t exp_status[] = {ACCESS_STATUS_SUCCESS};
            expected_status_set(CONFIG_OPCODE_MODEL_PUBLICATION_STATUS, ARRAY_SIZE(exp_status), exp_status);
            break;
        }

        case NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT2:
        {
            config_publication_state_t pubstate = {0};
            client_pub_state_set(&pubstate,
                                 m_current_node_addr + ELEMENT_IDX_ONOFF_CLIENT2,
                                 GROUP_ADDRESS_222);
            retry_on_fail(config_client_model_publication_set(&pubstate));

            static const access_status_t exp_status[] = {ACCESS_STATUS_SUCCESS};
            expected_status_set(CONFIG_OPCODE_MODEL_PUBLICATION_STATUS, ARRAY_SIZE(exp_status), exp_status);
            break;
        }
//add
        case NODE_SETUP_CONFIG_PUBLICATION_ONOFF_CLIENT3:
        {
            config_publication_state_t pubstate = {0};
            client_pub_state_set(&pubstate,
                                 m_current_node_addr + ELEMENT_IDX_ONOFF_CLIENT3,
                                 GROUP_ADDRESS_333);
            retry_on_fail(config_client_model_publication_set(&pubstate));

            static const access_status_t exp_status[] = {ACCESS_STATUS_SUCCESS};
            expected_status_set(CONFIG_OPCODE_MODEL_PUBLICATION_STATUS, ARRAY_SIZE(exp_status), exp_status);
            break;
        }

        default:
            ERROR_CHECK(NRF_ERROR_NOT_FOUND);
            break;
    }
}

I added #define GROUP_ADDRESS_333 (0xC004); and #define ELEMENT_IDX_ONOFF_CLIENT3 (3) in example_network_config.h.

Also in the cient , I set 0,1 to control the 1st group;2,3 to control 2nd group;4,5 to control 3rd group,

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

    ......

    switch(button_number)
    {
        case 0:
        case 2:
        case 4:
            set_params.on_off = APP_STATE_ON;
            break;

        case 1:
        case 3:
        case 5:
            set_params.on_off = APP_STATE_OFF;
            break;
    }

......
    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;

        case 4:
        case 5:
            /* Demonstrate un-acknowledged transaction, using 3nd client model instance */
            status = generic_onoff_client_set_unack(&m_clients[2], &set_params,
                                                    &transition_params, APP_UNACK_MSG_REPEAT_COUNT);
            hal_led_pin_set(BSP_LED_2, set_params.on_off);
            break;
    }

  ......
    }
}

I changed #define CLIENT_MODEL_INSTANCE_COUNT (3); and #define GROUP_ADDR_COUNT (3) in light_switch_example_common.h.

After I finished these work,I found that the servers can react to two groups and the 3rd group without any reaction,the log of debug in client:

any help i'll appreciate very much.
