ESP mesh with Raspberry Pi

[MazouniZakaria]

Hello, I'm working on a project about transport (bus) automation and i want to put in evey bus shelter a Raspberry Pi as a secured hotspot, and in every bus an ESP8266 that need to connect to that raspberry hotspot via Wifi once in range on that Bus shelter/hotspot.
I want the Raspberry to know/read every ESP8266 name/SSID connected to the hotspot and send this information (SSID) to a web application that i created (JavaScript) which will be implemented in the Raspberry itself.

I don't know if all this is clear and possible, cause i'm not experienced in programming, I just want to know how to start and if the ESPMesh can help me in my project.

Sorry I'm not sure I get your point, I don't see if there needs ESP-MESH.

Here some points about ESP-MESH:
ESP-MESH is based on chip ESP32;
ESP32 boards can connect to each other through wifi and transfer data, the distance between two boards is limited by the wifi performance, and I don't think normal wifi can cover 2km(distance between 2 shelters).
