I have many ESP8266 as STA that can collect some info from a sensor, and one Raspberry Pi3 B+ as AP, I need that every STA can send data to the RPi even if not directly connected. The idea is to have a mesh where every STA can talk with each other and if that is connected to the AP, send data over Cloud. So I want to ask you what is the best and simple way to achieve the target. What is the best configuration of WiFi ? Is possible to have a mesh and at the same time WiFi configured as STA? Is there some ready to go library to use? Examples?
Thanks a lot to everyone for the help
