Problem running 'internal communication' sample

[magnomp]

I flashed my esp32 dev board with 'internal communication' sample, but i'm not exactly sure if it's working properly

This is what I get from monitor:

(I skipped aparently redundant lines for brevity)

Is that normal? What is this sample expected to do? Is there any sample that shows me how to send messages to/from my desktop?

The internal communication example is supposed to demonstrate how a mesh network is built using multiple nodes. Once the mesh network is built, the root node will send a data packet to every other node in the mesh network. See Mesh API Reference and Mesh Guide

What is the goal of your application? Are you attempting connect a single device to your desktop or actually build a multi device mesh network? If the former, the Wi-Fi examples are probably more relevant.

OK, I found another thread related to this issue which mentions it could be the wifi channel, so I checked on my router that it is using channel 6 and configured my esp32 acordingly ant it seems to work now.

Is there a way to automate this? I mean, I don't have to worry about wifi channel for my laptop to connect, cant esp32 behave the same way?

Ok, my goal is to actually build a multi node mesh network. For now I'm playing with just one device to get familiarized with the technology

[ESP_yudong]

Looks like you've solved this.
ESP-MESH network is established on a fixed channel (1-14) now, so the channel is mandatory.

Is there a way to automate this? I mean, I don't have to worry about wifi channel for my laptop to connect, cant esp32 behave the same way?
