Max Mesh network size

As per the ESP Mesh document,
The size (total number of nodes) in an ESP-MESH network is dependent on the maximum number of layers permitted in the network, and the maximum number of downstream connections each node can have. Both of these variables can be configured to limit the size of the network.

There are:
a. maximum number of layers permitted in the network
b. maximum number of downstream connections each node can have

Does this mean a is always greater or equal to b? If not, what is b actually?

And what are the limitations for a and b?

If I use the mesh network in a very very long corridor, and all of nodes are connected as a straight line. For example, they are connected like this:

A <-> B <-> C <-> D <-> E <-> F ...

Is this possible? And what is the max number of layers for ESP32?

Hi eos1d3,

a. in the common version that we released on github, the maximum layers should be 25 (maybe more now, don't check);
b. the maximum connection directly to a node is 10 (ESP32 hardware limits when it works as an AP), however we suggest to set it at 6.

for your application, we have another special version(not released on github yet), in that case we design to have hundreds even thousand layers, for each layer maybe only several nodes, this is designed for application like street light.

For the current test, I suggest you can use the common version for now, there won't be much modification between these two.

That sounds great!!!
Is there any target date for its release??

I'm also very interested in that version. I've got an intelligent street light project that require many layers with 1 or 2 nodes. I've start tests with ESP32 MDF but I'm looking forward for dedicated version.

I would also really like to know when this version will be available. Are we talking months or years?
