My bad, I mean the ESP32/ESP8266 modules on their own don't have any LORA capabilities (The ESP32 has both Bluetooth BLE and Wifi, ESP8266 has just wifi).

However LORA itself does work over P2P, and a common module is the ESP32 + LORA + OLED screen, which I have used and tested without any gateways.

Also I think separate from LORA altogether - There's something called ESPNOW which lets the ESP's mesh network, but that's not related to LORA and I haven't ever played with it.
