"Mwifi also supports the way to fix the root node" What does this mean?

In Mwifi API, https://docs.espressif.com/projects/esp ... index.html

Mwifi also supports the way to fix the root node. In this case, the nodes in the entire ESP-MESH network cannot communicate with the external IP network through wifi.

What does this mean? What is "FIX"?

Hi eos1d3,

It means when the devices is powered on, it can only be root node. As this root don't connect to a router, then the whole network under this root won't be able to communicate with the external IP network.

So it is "no_router" mode in the examples, right? But I think the wording is confusing.

Thanks!

Yes, it works in no_router situation, but even if there is router, this kind of networking still works.

In some special scenario, we may need some devices (audio devices with WROVER module for example) to be root node as it has more powerful computing capacity, to control other nodes(bulbs with ESP32-S0WD chip), then in this system we may need the smart speaker to become the root.
