How to add mesh into nRF5 SDK v14.1/v15 BLE application ?

[Hung Bui]

What do I need to know to add mesh functionality into a normal BLE application ?

This is an update for combining Mesh SDK v2.0.1 and nRF5 SDK v15

 

In Mesh SDK v2.0.1 it's now easier to be used concurrently with the SDKv15. There is only a few modification needed. 

To add mesh into your BLE project you would need:

• Extract a fresh copy of nRF Mesh SDK to \components\mesh
  
  

• Include all the source file from Mesh example you want to clone. 

• Include all header folders from Mesh example in Project Option -> Common -> Preprocessor -> Include Directories

• Include Preprocessor Definitions in mesh example ( same setting tab as above).

• Remove mesh_softdevice_init.c and any call to it in main.c The softdevice is handled by nrf_sdk_ble module already. 
• Edit main.c to add mesh init functions and defines.

• Add nrf_mesh_evt_handler to SOC observer list with NRF_SDH_SOC_OBSERVER for example:

  void nrf_mesh_evt_handler(uint32_t sys_evt, void * p_context) {

   nrf_mesh_on_sd_evt(sys_evt);
  

  }

  NRF_SDH_SOC_OBSERVER(m_nrf_mesh_observer, 0, nrf_mesh_evt_handler, NULL);

• Increase BLE advertising interval. We are seeing Mesh performance affected when advertising interval <100ms. 

 

Attached here is an example combining ble_app_uart with light switch server. To test this you would need:

• Extract nRF Mesh SDK into \SDKv15\components\mesh
• Extract the example into \SDKv15\examples\ble_peripheral
• Test it using the mesh's light switch provisioner and client in Mesh SDK v2.0.1

Any changes / updates for use with 2.2.0 SDK?

I also have the same question.
