How to connect two or more groups with one server? (nRF52 Mesh)

[JK0201]

Hello to everyone.
I´m starting to work with Mesh configuration in nRF52 SDK.
I was testing the "light_switch" example as client and server in Mesh v3.10, provisioning with a mobile device with Android App: "nRF Mesh". It worked fine.
Now, I want to make use of "groups" model (like the image above). I know that a group can has many nodes inside (red area), but I got a doubt: Can a server control the messages of two or more groups? (blue area)


I´m trying to make a configuration like previous image, but I want to control the network with a mobile, so I have to make it a only server. And, if I have only one server, to test the "groups" model, I must have several groups with the combination of those three devices (all are nRF52).
How can I do that?
I hope you can help me.

Hi.

Can a server control the messages of two or more groups? (blue area)

Yes, this is possible.

I think the easiest way to solve this, is by having the different server nodes subscribe to multiple publication addresses.
For example;
If we look at the first picture in your question. You can have the "Bedroom" nodes and the "Garden" garden nodes both subscribe to the same address.

Hello Joakim, thank you for answer.
I understand what are you saying, but to do that, I need to know where the entire information a configuration of the nodes are saved, to reconfigure them and put different addresses.
Now, I´m using dynamic provisioning with "light_switch_provisioner.h" example in a nRF52 DK. How to rewrite the code to assign the servers to different addresses in the same client?
More important, how to put different addresses in only one client?

Hi again.

Sorry about the delay.

If you haven't made any progress on this I suggest that you take a look at the thread below and the answers from my colleague, Hung.

Don't worry about that.
I solved the problem "playing" a little with the Android App.
A server can be suscripted to different addresses of the same client, but the client has to has different elements that may be able to publish a different address.
Thank you for the support!

Hi

I want to know whether the light linked both to the kitchen and the dining room shown in the first picture can be controlled by two different groups .i.e., did the same light subscribe to both the rooms.

If yes please help me out with the same. I am presently working on a similar home automation.

Hello, sorry for the waiting.
First, you have to configure the group addresses in each client (Select client -> second element -> Generic OnOff client -> Publish).
Then, configure the server that you choose to be connected with those addresses (Select server -> second element -> Generic OnOff server -> Subscribe).
You must put one of the same addresses that you choose on clients configuration. A server can work with more than one group address, you have to configure all manually the first time with the first device.
