Mesh network topology

[Milogic]

Hi,

I'm using an application based on the light switch provisioner example (BLE mesh 2.2.0).

I'm wondering if the following is possible:

- Request all provisioned nodes in the network (locally, so is it stored somewhere?)
- See the nodes in direct range?
- Is it possible to see which relay modules were used to deliver a message?

I'm hoping to create a sort of topology of the current network.

Thanks,

Milo

Hi Milo.
Sorry about the delay.

Not sure what you mean by "Request all provisioned nodes". Could you elaborate?

There is no built in function to do this. There isn't any routing in the mesh, and adding this would add quite a lot of overhead to the communication.

Take a look at this thread for some suggestions on how it can be done:

You can do this by sending a group message to all the nodes in the network with TTL = 1. Have all the nodes that receives this message report back that they received it. That way you will know all nodes in direct range.

Best regards,
