Bluetooth Mesh - relaying?

[slowhand]

Hi,

I have couple of nRF52832 boards, nRF5-SDK-for-Mesh (v. 0.9.2) and good will to demonstrate some simple multihop mesh.

I already tested the light control example, and saw it working with one client and 3 servers while they were all on my desk and all the 3 servers within the client's range.

However, to make multihop (at least two) ... do you have any tips if can I demontrate relaying/multihop with these example codes somehow?

I set up multiple sets of the Light control demo and then used a single client to command all the servers. I then could verify that physically remote devices did not turn their LEDs on or off without intermediate devices relaying the messages.

Ok. Now I tried something similar(?) with 4 devices: I moved the client from my desk to a separate room nearby and one of the three servers to another room in another direction. Scanning with nRFConnect on my desk I could still see all the devices, but scanning in the room of the client I could not see the distant server. So I thought it is 2 hops from the client to the distant server. I even got the led on in the distant board (once, but not anymore later).

BUT, I think the antenna is better in nRF52832 than in my Honor8 (with nRFConnect). So, I can't be sure if there was really two hops or if the client was able to command the distant server directly.

How to monitor what really happens?!
