Some questions about Bluetooth Mesh [Copy link]

Recently, due to work needs, I started to get in touch with Bluetooth Mesh. I looked it up and found that Bluetooth Mesh was not long ago, probably in 2017, so it has been 4 years now. Although I am new to Bluetooth Mesh, there is more information than then. I also looked at the relevant information about Bluetooth Mesh and learned that there are five roles: provisioner, client, server, proxy_client and proxy_server. I haven't started a project yet. I want to know if a Bluetooth device can be in several roles at the same time? For example, if device 1 is the provisioner and server role, and device 2 is the server role, then the two devices can form a network.

If it is not possible to have two roles at the same time, then the provisioner device only has the function of configuring the network and cannot have other functions. Isn't this a bit of a waste? Moreover, in this case, if it involves a larger range of scenarios, multiple provisioner devices will be required, which is even more wasteful. If it is not possible to have two roles at the same time, is there a role switching mechanism, such as being a provisioner for a period of time and a server for a period of time.

I have just started learning Mesh and there are still many things I don’t understand. My understanding of Mesh is not yet in place. I hope experienced experts can give me some advice!

It is possible for one node to have multiple roles. Here is a post by nordic for reference. https://devzone.nordicsemi.com/f ... t-model-on-one-node

ON's BLE mesh server can add relay function by itself

Provisioner can be used with mobile phone

Look at ON's routine.

Provisioner uses mobile APP to configure client and server

Client can add proxy

Server can subscribe to push

But there is not much information on ON

I'll see when the time comes. I've never played with Bluetooth Mesh. I spent the whole day looking at it, but I still don't understand much.

After looking at it, I still couldn't solve the problem I wanted to know, so I slowly studied it

I think it is multi-master multi-slave multi-point communication
