Thank you Amanda,

as my understanding, the node count limitation is because of the provisioner, but in my case i use the mesh app to provision.

and i have more than 20 sensors as clients, and more than 20 relay nodes as servers, with one publication address in client communicates with one subscription address in server , that's why i want to set Client node to 30 and server node to 30,

in light switch example, 1 client and 30 is ok, so i guess 4 clients and 26 servers is ok, how about 30 clients and 30 servers in one mesh net.

Thank you in advance!

Hi Wei,

The main limitation is when we use nRF for provisioner, as we are limited by how much provisioning data the nRF can store. That is the main reason for max around 30 nodes in our examples.
The same goes to a certain extent for nRF based nodes when it comes to the number of models they can have and the number of addresses they can publish to, etc.
In a Bluetooth mesh network, you can have a very high number of models in total. There is no limit to the number of nodes listening to a group address. It is hard to tell what you need as we do not know what is the use case.
You may need that number of clients and servers, but please be aware that one node can have several models (and also several of the same model.)
If you increase CLIENT_NODE_COUNT and SERVER_NODE_COUNT in our examples, you may need to extend other values as well.

OK，so 30 clients and 30 servers in one mesh network is ok，right？

Hi,

The server node count is limited to 30 controlled by a single client. Therefore, it depones on how many server nodes are controlled by a client node.

Please see this post and this post.
