Sure, the ESP32 will connect to whichever mesh node provides the best 2.4 GHz signal

- It monitors CSI from that specific node (the one it's associated with)

- If the ESP32 roams to a different mesh node, it will start monitoring CSI from the new node

The system doesn't care about the router's internal mesh topology, it just needs a stable connection to receive CSI data from the associated access point.
