Yes. The client should publish to the server's unicast address. In you case, because you want to control the light on Server 2, the Client must use Server 2's address, not Server 1's.

Thank you, Didrik.

You mean that I need to change the Generic on/off address from Server 1 to Server 2, right?

In addition, could you let me know how to test of development kits objectively?

Now I'm using the 'RTT viewer'.

That might be the cause of the problem. According to our documentation on the Bluetooth Mesh architecture, a relay node will forward the packet only if the node is not the destination. However, if both the relay and the server has the same address, the relay will believe that it is the destination, and not forward the packet.

Thank you, Didrik.

Okay, this is my test situation.

I settled down Client at one point. And the server 2 settled on the other point which is so far from client. (Client cannot control Server 2 because it is so far.)

If Server 2 is close, client can control. However, client cannot control if Server 2 is far.

Therefore, I put Server 1 between them. (between Client and Server 2).

They are already provisioned, and Client can control Server 1.

I hope that Server 1 work very well, so it can work as relay node.

I think that Server 1 can relay the 'generic on/off message' from Client to Server 2.

However, it can't! 😞

One of Client's generic on/off unicast address is same with Server 2 address.

[quote userid="81181" url="~/f/nordic-q-a/64266/test-relay-node-by-using-nrf-mesh-light-switch-example/262340"]What do you mean by that?[/quote]

That's why I wrote that Client can't control Server2 directly. ( Server2 is far from Client, so I think that Client can control Server 2 via Server 1.)

Thank you for reply.

I will waiting for your reply 🙂

Sincerely,

Minsu Kim.

Hi, and sorry for the late reply.

At the moment, all our mesh experts are on vacation, but I'll do my best to help you until they are back.

I already had many tests, but I'm not sure that I used relay node...

Could you clarify what you are meaning here? Why are you not sure if Server 2 acts as a relay node or not?

[quote user=""]Client can't control Server 2 directly.[/quote]

What do you mean by that?

Is the client able to control Server 2 at all?

Best regards,

Didrik

Also, I set the Generic On Off Server 'Group address'. And then, Server 2 Subscriptions address set the same group address.
However, it doesn't respond, either. 😞

In 'nRF Mesh app', there is a slot 'Publish address' (Server 1 - Generic On Off Server). So, I wrote the unicast address of Server 2. But server 2 doesn't respond.
