The 'HOST' #define in light switch examples

So I think there is no issue. But only after this discussion is the confusion clarified :-) Thank you - I have my answer now

Unfortunatly I cannot do that because mesh_softdevice_setup() is called by mesh_core_setup() and that is called by main() In the light_switch_client example app. But mesh_core_setup() is never called in the light_switch_server example app.

And just checked that mesh_softdevice_setup() is not directly called either in the server application.

In fact in the server app, the softdevice is enabled in the function softdevice_setup() which is directly called by nrf_mesh_node_config() which is in turn called in main().

However I see that nrf_mesh_node_config() only calls softdevice_setup() if the softdevice is currently NOT enabled. So as you say it should just work out.

I don't think you should define "HOST" in your project. If it's only about the initialization of softdevice, why not simply skip calling mesh_softdevice_setup() inside mesh_code_setup() ? We have an example of combined mesh and BLE, and it worked fine.

Alas defining HOST will mean that it will break the application because in the function nrf_mesh_on_sd_evt() I see that the function timeslot_sd_event_handler() is only called if HOST is not defined.

I think Nordic needs to add some other #define to be used if the mesh stack is integrated into an existing application

I note that if the HOST is defined the softdevice initialisation code is not called. Given I plan to integrate the mesh code into our standard firmware image where we already enable the softdevice I actually do not want that code to be called in the mesh stack. But now given you mention it is for unit testing I am nervous that I define HOST for my project.

Can you make any recommendations for my integration use case?

Hi Mahendra,

The "HOST" define is used when we do unit test of the modules. We could have used different name to make it clearer. Don't think the application need to do anything with that.
