Implementing a mesh network

[leenowell]

Hi all,

I am looking to implement a mesh network using ESP8266's. Looking at the following spec, this looks exactly what I need.

https://docs.espressif.com/projects/esp ... /mesh.html

The main criteria is that they don't need to connect to a wifi router (besides the root node) and continually manage the mesh automatically.

Looking at the corresponding API documentation from here,

https://docs.espressif.com/projects/esp ... _mesh.html

It looks like this is for esp32 only. I have seen the painlessMesh library but unfortunately this seems to require the nodes are connected to the wifi router.

Am I missing something? Is it possible to implement the mesh as described on an esp8266?

Thanks in advance for your help

Lee.
