Status check for provisioned BL Mesh Devices

[timvan]

Hi,

I am trying to develop the interactive_pyaci serial interface so that it can restore itself once it has been closed. 

To do so it would be useful, once the db is loaded, to check if the devices are still connected to mesh (presuming they're on) - is there a preferred (BLE Mesh Spec Compliant)  Health Check / Status Get message for the devices? 

Thanks in advance,
Tim

Setup:

- mac OSx
- nRF5 SDK for Mesh v3.1
- 2x PCA10040 nRF52 Dev boards with 1x Serial Example and 1x Light Switch Server example

Yes, there is a health status message in Bluetooth Mesh. If you run the regular light switch example with the provisioner example on a 52 DK, see the relevant code below:

static void app_health_event_cb(const health_client_t * p_client, const health_client_evt_t * p_event)
{
    switch (p_event->type)
    {
        case HEALTH_CLIENT_EVT_TYPE_CURRENT_STATUS_RECEIVED:
            __LOG(LOG_SRC_APP,
                  LOG_LEVEL_INFO,
                  "Node 0x%04x alive with %u active fault(s), RSSI: %d\n",
                  p_event->p_meta_data->src.value,
                  p_event->data.fault_status.fault_array_length,
                  ((p_event->p_meta_data->p_core_metadata->source == NRF_MESH_RX_SOURCE_SCANNER)
                       ? p_event->p_meta_data->p_core_metadata->params.scanner.rssi
                       : 0));
            break;
        default:
            break;
    }
}

I also recommend to take a look at the health_client.h header file.

Thanks Bjorn, is there a way to request to the Health Status - such as a "health status get"?

[timvan]

And preferably request this status update using the Serial device with the Interactive_pyaci

[Bjørn Kvaale]

Yes, I believe that should be possible.Take a look at the readme.md file here: nrf5_SDK_for_Mesh_v3.1.0_src\scripts\interactive_pyaci

I also recommend taking a look at the different python files to see which commands are available for you to use.
