Newbie Mesh

Postby rsimpsonbusa » Tue Oct 16, 2018 11:17 pm

Hi guys, new to Mesh but years with ESPs (Arduino and esp-idf, ESP8266 and ESP32).

One general question regarding ESP32 mesh network that after reading a lot still can not seem to grasp completely(typical newbie :D ). Can we communicate, and how, between different nodes-leaves or "everything" has to go to the Root that will send the "message to the external world"? In other words, mesh is just an AP "range extension" for far away nodes.

I would hope the Root node be the AP, sort of directing "traffic", from Node A to External World, from Node A to Leaf F, from Leaf F to Root(not external world), etc.

Regards,

RSN

Ill answer myself. With post viewtopic.php?f=21&t=5714 the answer is Yes but very elaborate. the ROOT can not get to a leaf, so ROOT is not a dispatcher/controller.

Any two nodes in mesh network could communicate using the shortest route.
Here's the brief of esp_mesh_send() #doc
Send a packet to any device in the mesh network.
Send a packet to external IP network.
