General issue report

I test internal_communication project on my esp32-s3 and esp32-c3.

but i found it can not connect. monitor say fail to find a network.

i watch the readme.md, it say configure the mesh network channel, router SSID, router password and mesh softAP settings. I dont known to moify, so I use default setting, is ok??

follow is my log, can you help me test the example.

Hi, Is your network a mobile hotspot? If not, please try to connect another network or try to change authmode.

Best regard.

no, it connect to anotner esp32 device.

@m986883511 This is just an example, do you have a router whose ssid is test and password is 12345678 in your environment？

https://docs.espressif.com/projects/esp-mdf/en/latest/api-guides/general-notes.html#network-configuration this guide say it doesnot need a external router. I want to use [Automatic root node election via the physical layer protocol] this way.

Is that what you're saying?

As soon as a root node is established, ESP-WIFI-MESH network configuration process becomes independent of routers.

What this means is that after root has been generated, the creation of the mesh network and the router are independent. However, when all nodes initially elect the root node, they need to elect the root node according to the rssi relative to the router. So you need to set a valid ssid and password.

thank you for you help, you are right.
