How to get unicast address on mesh server.

Hi,

I have add beacon function to "light_control_server" project. I want to every server broadcast their unicast address. Could do kindly teach me how to do this. It's better if give me a piece of code.

The sender address is included in every packet. Check out the src field in nrf_mesh_evt_message_t in a packet you receive on access layer , for example in mesh_msg_handle() in access.c

Thanks. Do you think broadcast unicast address beacon is a good idea? any issues? like security or other issue. Any better idea, if I just want to give a unique name to each device for indoor positioning.

Could you describe your application ? How would you want the indoor positioning is utilized base on the mesh ?

Yes. I want to make a bluetooth mesh backbone networking with beacon indoor positioning, which is suit for shopping mall or underground parking.

Firstly I want to implement a simple mesh+beacon networking. Beacon take care of indoor positioning and mesh take care of DFU ex. All of those nodes should be reply nodes and powered continually. They are backbone of mesh network.

I want the indoor positioning is utilized base on the mesh in the future. It's should be a self organizing(positioning) system, if we follow some simple rules when place these relay nodes, like place them in 30 meters distance grid layout.

Please give me some advises, ether mesh networking or other potential one.

Still, I don't know what your indoor positioning system based on. It's a beacon network so that the phone user can scan detect where he is in a building ? Or you will have a more complex system ?

The beacon ID doesn't need to be the same as the mesh unicast address. You can always use the mesh to configure the ID of a beacon or assign any data to it.

You would need to be more specific on what exactly you want.
