Mesh 3.2: LPN GET and receiving STATUS

[Jesper W.]

Based on the experimental_lpn example if have ported at application (light switch) to work as a low power node.

Everything work fine on the lpn node where i use the generic_onoff_client to send button on/off to a server node.

I now want to 'request' the generic_onoff_server status issuing a GET from the client. This is also received on the server and a STATUS published.

Both server and client have been setup to use same app-key and group address on publish/subscribe.

To help me verifying what is send/received, i have added debug-print (__LOG) in app_mesh_core_event_cb()  on NRF_MESH_EVT_MESSAGE_RECEIVED and NRF_MESH_EVT_TX_COMPLETE.

I using the light_switch_server example as server and have verified that the light_switch_client example works fine receiving STATUS, but not the exprimental_lpn 

Are there any restriction in the experimental_lpn that prevent me from receiving STATUS ?

I have also made these changes to the mesh-init and main loop .. allowing me to use APP_SCHED (Event Scheduler) .

void mesh_init(void)
{
    mesh_stack_init_params_t init_params =
    {
        /* Run application and mesh event handling in main loop using app_scheduler:
           When using the APP_SCHED to post event, the irq_priority must be changed from 
           NRF_MESH_IRQ_PRIORITY_LOWEST to NRF_MESH_IRQ_PRIORITY_THREAD in order to avoid 
           mesh app assert. */
        .core.irq_priority       = NRF_MESH_IRQ_PRIORITY_THREAD, //NRF_MESH_IRQ_PRIORITY_LOWEST,
        .core.lfclksrc           = DEV_BOARD_LF_CLK_CFG,
        .core.p_uuid             = NULL,
        .models.models_init_cb   = models_init_cb,
        .models.config_server_cb = NULL //config_server_evt_cb
    };
    ERROR_CHECK(mesh_stack_init(&init_params, &m_device_provisioned));

    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "m_device_provisioned:%d\n",m_device_provisioned);

    /* Register event handler to receive LPN and friendship events. */
    nrf_mesh_evt_handler_add(&m_mesh_core_event_handler);
}

    for (;;)
    {
        app_sched_execute();
        bool done = nrf_mesh_process();
        if (done)
        {
            sd_app_evt_wait();
        }
    }

Did I missed that at LPN can only received STATUS etc after establishing a friendship with a server ?

Hi,

In order for a node using the Low Power feature to consistently receive messages, it must establish a friendship with a node with the Friend feature, yes.
