It is missing ESP-WIFI-MESH / ESP-MDF tho

ESP-WIFI-MESH / ESP-MDF hasn't been updated in 4 years.

It appears that support for ESP-MDF ended on October 21, 2022.

There are several forks of ESP-IDF V5 available, but they are not suitable for production development.

@nopnop2002 Yea, I know, our product still running on it.

Could at least contain ESP-WIFI-MESH if not MDF, that is part of official IDF and supported. I guess that would be for documentation feedback.

Yes, you are correct.
ESP-MESH is a standard feature of ESP-IDF.
An ESP-MESH example is available here.

The differences between ESP-MESH-LITE and ESP-MESH are published here.
https://github.com/espressif/esp-mesh-l ... r_Guide.md

Among them, the following is particularly important:

The biggest difference between ESP-MESH-LITE and ESP-MESH (also known as ESP-WIFI-MESH) is that ESP-MESH-LITE allows sub-devices in the network to independently access the external network, and the transmission information is insensitive to the parent node, which greatly reduces the difficulty to develop the application layer.

ESP-MESH-LITE utilizes this ESP-IoT-Bridge Solution.

In both ESP-MESH and ESP-MESH-LITE, communication from LEAF nodes goes through the root node.

If you want to use 1,000 LEAF nodes, you need to make the transmission interval large enough, otherwise the processing capacity of the root node will be exceeded.
