Get source address of publisher node in nrf mesh

[Dhaval Dalvadi]

I have used light_Switch example from nrf mesh sdk nrf5_SDK_for_Mesh_v4.2.0_src

I like to get the client source address in nrf_switch_server 

what should I need to modify to get client source address in below function

static void app_onoff_server_set_cb(const app_onoff_server_t * p_server, bool onoff){

........................

}

Thanks

Hi Dhaval, 

You would need to look inside generic_onoff_state_set_cb() in app_onoff.c to find the source address of the set message , inside p_meta. 
This is the function that will trigger a transition and the transition when completed will call onoff_current_value_update() -> app_onoff_server_set_cb().

Hi,
I found same while debugging too
but how can I get source address inside onoff_current_value_update() function so I can pass it too app_onoff_server_set_cb()?

static void onoff_current_value_update(app_onoff_server_t * p_app)

I only gets app_onoff_server_t which does not include source address so unable to pass to app_onoff_server_set_cb()

Thank you

You would need to pass it from generic_onoff_state_set_cb(), either by calling your own callback to main.c inside that function, or pass it through the process of transition which can be a little bit more complex. Or you can store it in a variable and then pass the variable back to main when  onoff_current_value_update() is executed. 
But I think calling a callback inside generic_onoff_state_set_cb() would be the the most straight forward.

Thank you very much
Is it possible that you guide small step about

 pass it through the process of transition

I think that would be more professional way and can be help full in many application

Hi Dhaval, 

We don't have an example for that. But my understanding is that you need to add the source address to the p_app and also to the app_transition_t.

Note that the app_onoff.c and app_transition.c are on application layer, so you have the full control of what you can do with them. It's not something that need to be qualified with the spec. So you can call a callback to the main application, or you can process what you need to do in generic_onoff_state_set_cb() also.
