Using Mesh SDK with nRF5_SDK15.0

[Aftab]

Hello,

We have developed a GATT based application based on nRF5_SDK_15.0 (Bluetooth LE without mesh). We want to add mesh functionality in this code as you described in this ticket:

https://devzone.nordicsemi.com/f/nordic-q-a/43167/nrf5-to-mesh-upgrade

To achieve this I'm following this guide: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v3.1.0%2Fmd_doc_getting_started_how_to_nordicSDK.html

I have copied the mesh, models, external and examples folders into SDK 15 project and added paths to the projects. Next it says:

Add the following preprocessor symbols to the nRF5 SDK example's project file:

Fullscreen

1

3

NRF52_SERIES

NRF_MESH_LOG_ENABLE=NRF_LOG_USES_RTT·(because the logging in the mesh stack relies on RTT)

CONFIG_APP_IN_CORE

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

NRF52_SERIES
NRF_MESH_LOG_ENABLE=NRF_LOG_USES_RTT (because the logging in the mesh stack relies on RTT)
CONFIG_APP_IN_CORE

I'm not sure in which files to add these symbols. Same goes for following piece of code:

#include "nrf_sdh_soc.h"

#define MESH_SOC_OBSERVER_PRIO 0

static void mesh_soc_evt_handler(uint32_t evt_id, void * p_context)

{

nrf_mesh_on_sd_evt(evt_id);

}

NRF_SDH_SOC_OBSERVER(m_mesh_soc_observer, MESH_SOC_OBSERVER_PRIO, mesh_soc_evt_handler, NULL);

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

#include "nrf_sdh_soc.h"

#define MESH_SOC_OBSERVER_PRIO 0

static void mesh_soc_evt_handler(uint32_t evt_id, void * p_context)
{
nrf_mesh_on_sd_evt(evt_id);
}

NRF_SDH_SOC_OBSERVER(m_mesh_soc_observer, MESH_SOC_OBSERVER_PRIO, mesh_soc_evt_handler, NULL);

Can you please share some more details/documentation how to achieve this? My end goal is to add mesh functionality to already developed GATT application and utilize the (developed) code as it is (if possible). What is more easier, adding SDK15 code to mesh or adding mesh to SDK15?
