Oh yes they can connect p2p. The ESP32/ESP8266 modules you see at 6$ don't have a lora module though, that's extra (but still a good combo) more like ~15$.

I bought two with old screens and don't have any base stations. I beleive they can be connected in mesh with more too (not sure how many channels are needed)!

When you say they "don't have a lora module" but they still work in p2p, what does that mean? Parts are done in software that normally would be in a hardware module?

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.

I bought some LORA module for 3eur (AI Tinker RA-01).
