No mesh provisioning when adding mesh to SDK 14.2.0 UART example

[Hieu]

I have been working on "merging" SDK for Mesh's lightswitch client example and SDK v14.2.0 UART server example, mostly following the document on this site, with some changes where applicable.

I ended up with a firmware where the NUS application works fine, but there is no mesh activity. RTT log from the mesh side report up to Setting up access layer and models.

Could anyone give me an idea on what I am missing?

Here is my project: ble_app_uart_and_mesh.zip

And here is how I have the SDKs set up:

• Mesh v0.10.0-a root
  • bin
  • CMake
  • ...
• nRF5 SDK v14.2.0 root
  • components
  • config
  • ...
  • project
    • ble_peripheral
      • ble_app_uart_and_mesh

Update 1

Debugging shows that in my SD_EVT_IRQHandler(void):

void SD_EVT_IRQHandler(void)
{
    nrf_sdh_evts_poll();

    /* Fetch SOC events. */
    uint32_t evt_id;
    while (sd_evt_get(&evt_id) == NRF_SUCCESS)
    {
        nrf_mesh_on_sd_evt(evt_id);
    }

    /* Fetch BLE events. */
    uint16_t evt_len = sizeof(m_ble_evt_buffer);
    while (sd_ble_evt_get(&m_ble_evt_buffer[0], &evt_len) == NRF_SUCCESS)
    {
        nrf_mesh_on_ble_evt((ble_evt_t*) &m_ble_evt_buffer[0]);
        evt_len = sizeof(m_ble_evt_buffer);
    }
}

Code execution does reach while (sd_evt_get(&evt_id) == NRF_SUCCESS), but never go inside the loop. I suspect that nrf_sdh_evts_poll() consumed all events and therefore no event got passed to the mesh modules. Could this be the issue? And if so, how could I fix it? I tried to look into nrf_sdh_evts_poll(), but frankly speaking it is really foreign...

Update 2: Fixed issue in Update 1 by modifying nrf_sdh_ble.c and nrf_sdh_soc.c:

nrf_sdh_ble.c

static void nrf_sdh_ble_evts_poll(void * p_context)
{
    ...
    
    while (true)
    {  
        ...
        
        // Added Mesh handler
        nrf_mesh_on_ble_evt(p_ble_evt);
    }

    ...
}

nrf_sdh_soc.c

static void nrf_sdh_soc_evts_poll(void * p_context)
{
    ...

    while (true)
    {
        ...

        // Added Mesh handler
        nrf_mesh_on_sd_evt(evt_id);
    }

    ...
}

Now nrf_mesh_on_sd_evt() and nrf_mesh_on_ble_evt are called for sure. However other handlers in the mesh SDK, for example, mesh_evt_handler() in provisioner.c, are never reached. I am out of clue again

Have you taken a look at this devzone case? This has been done in SDK v 14.1 & Mesh SDK v 0.10.1 and is very similar to your usecase. Also, there are a few bugs in the Mesh SDK 0.10.0, so you should definitely use the newest mesh sdk (i.e. v 0.10.1).
