Glad it worked out for you! I have replied to your other thread and I suggest we continue there :)

Hi Mttrinh and thanks for your help! It worked finally, I am very happy. 🌞

Now, that this step is achieved, I would like to move on to combining these two examples with sending a notification on the phone. Could I ask your input on that as well? It's a build-up on the existing issue, which you just helped me with. I created another question, so that it's all organised.

Thank you very much for your help and I wish you a great day!

I forgot to tell you that for the Thingy you need to follow the steps in thingy52-mesh-provisioning-demo and flash the thingy firmware. Not the client firmware found in the Light switch example from the SDK.

As for the nRF52840 board, you have flashed the correct server example.

Hi, thanks for the answer. Yes, I use nRF Mesh for provisioning all devices.

Step 1, detailed: downloaded from nRF_Mesh_v3.2.0\examples\light_switch, the client, respectively the server code on the boards. The set-up is the following, excluding the top-most Thingy.

These are the loaded files on the two boards:

For the Switch (Client) - thingy:52:

For the End Device (Server) - nRF52840:

However, pressing the button on the client does not trigger any LED on the nRF52840. I am not sure how I should start debugging this issue. Thanks.

Are you using the nRF Mesh app to provision the devices?

For step 1, can you give me the exact steps you have done?'

As for step 2, the relay feature is enabled by default so you only need to provision all three devices into to same Mesh network. The server node in between will act as relay node, assuming it is in range of both client and server(end destination).

Hi Mttrinh!

Thank you for the quick and very well-explained answer.

[quote userid="15475" url="~/f/nordic-q-a/64914/light-switch-demo-versus-thingy52-mesh-provisioning-demo/265153"]un the nRF52840 as a light bulb/switch and the thingy52 as the other one?[/quote]

Yes - I try to achieve exactly what you said!

Eventually, my reasoning is to place one Thingy in the middle as a relay. Because from what I read, in a mesh network, all nodes which are not destination will just forward the messages. Therefore, my first step would be:

Step 1: [client (nRF52840)] ------> [server (Thingy:52)] - not working at this moment. Need to figure out.

And after this is done, the next step would be:

Step 2: [client (nRF52840)] ------> [server (Thingy:52), relay] ------> [server (Thingy:52), final destination] - final goal.

If you have any suggestion how to achieve my first step, or if you think I can try something simpler and just do Step 2 directly, I am open for any suggestions 🙂

Thank you!

Hi,

[quote user=""]However, from my perspective, they achieve the same goal: publish-subscribe; light switch-light bulb.[/quote]

Yes, you are correct. Both demo's are doing the same. meaning they both showcase how you can provision and configure a node to be a light switch or a light bulb.

The Thingy firmware is equiped with both Generic OnOff client and Generic OnOff Server, so it can be both a light switch and a light bulb. While the Light switch demo have two separate firmware: The light switch client(light switch) and light switch server(light bulb).

I assume you want to run the nRF52840 as a light bulb/switch and the thingy52 as the other one?
