ESP-WIFI-MESH broadcast from one node to all other nodes in mesh

[GhanayemMuh]

Hello. I am working on a project involving 30-50 esp32-s3 nodes that can communicate with an external server. from what i was able to understand, only the root node can be directly connected to the server. but in my project, i want any update on the server to be sent to all mesh nodes in the network, not just the root node.
I am having trouble searching up for example codes or clear documentation on how am i supposed to implement this. basically i want to understand how i can "broadcast" a message from any node to any node in the mesh. and if there exists any already implemented functionality for doing so.

thanks.

There is Mesh Internal Communication Example.

from what i was able to understand, only the root node can be directly connected to the server.

In esp-mesh-lite, all nodes in the mesh can connect to the server.

Leaf nodes can send messages to the root node.
The root node can send messages to all leaf nodes.
