How to identify a non provisioned node with the Thingy mesh demo

[mr_jj]

According the the instructions for the Thingy mesh demo, it is possible to manually provision new nodes. Is it possible to identify the unprovisioned node first by sending a command to blink its LED (or similar).

I do not believe it is possible to do this with the Mesh demo directly, but it might be possible to achieve this by changing the code. Normally, the provisioner will need to provision & configure a node before it is able to ask the node to turn on its LED. What you could also do is to provision all nodes that have a certain UUID & filter out nodes that should not be provisioned. This is how the light switch example does it in the Mesh SDK v2.0.1.

Thanks for your answer. What would be needed to change in the code to communicate to an unprovisioned node with a certain BLE address that it should blink?

If you take a look at the latest mesh sdk, you notice that the provisioner sends out a "Link Establishment Request" to the provisionee. If you find out where this is in the code, you can tell the LED to blink when this event occurs. That way, you can figure out which node is being provisioned at a certain time. My guess is you want to do this to be able to tell which unprovisioned node you want to provision at a certain point in time. Is this a correct assumption?
