Any suggestions on a simple library to add MESH capabilities to an M5StickC

I don't want it to interfere with normal WiFi operation, and I just need to broadcast small packets of data between multiple M5StickC's that are not connected to WiFi to one that is

Essentially (M5StickC x 10 not on WiFi) ---> MESH ----> M5StickC on WiFi

I am looking for a simple example that does the following:-

1. Define the kmodel to use (e.g. "face", "car" etc.)
2. Each time a object is detected, send metadata through the Grove port so I can process the events on an m5StickC
