The server can be provisioner?

[rcosta]

Dear all,

I want to create a star network, composed by one gateway and a limited number of nodes. The nodes periodically send information to the gateway. I am using the nrf52 for mesh. I have the following questions:
The gateway can be simultaneously server and provisioner? The gateway should have a element and model for each node?

Best regards, Rafael Costa

Are you sure you want to use Mesh to create a star network ?

In the SDK light switch example, we have one device acts as client(s) and several servers, it is just an example. Actually there are several elements on the client, each element control one server.

You don't need to follow that, you can use one single client to control different server or you don't really need to use server - client model at all, if it's better for your application. To send a packet from one device to another device, you just need to match publication address with the subscription address or the unicast address of the other device.

The provisioner can be on any device, doesn't need to be client. But for now we don't support multiple provisioners.

Dear Hung Bei,

I am starting on Bluetooth for mesh. The final goal is to create a mesh network, composed by one gateway and many nodes, the gateway should be the provisioner.

To be able to create my application first i need to learn some basic concepts and study the SDK. I am studying the light switch example included on the nrf52 SDK for mesh, i already executed this example. On the example i not understand some functions calls and data structures. After some time analyzing the example, i conclude that there is a lot of things that are necessary to do before two nodes can communicate. Please can you tell the best approach for somebody that is starting on Bluetooth for mesh? Please can you provide me some resources?

Any help will be very appreciated.

Best regards, Rafael Costa

The resource that I would suggest you to have a look are:

• Bluetooth Mesh spec (Mesh Profile) www.bluetooth.com/.../mesh-specifications

• Mesh SDK's getting started guide (starts with the provisioning part) infocenter.nordicsemi.com/.../md_doc_getting_started_getting_started.html

• Lightswitch example source code.

Dear Hung Bui Thank you very much for the help. Before my post I was already studying the Mesh SDK´s getting started guide. I will study the suggested resources, If a have any question i will create a devzone case. Thank you very much.
