Photon No network coverage | Data transferring between two Photons

Im currently working on a project that requires us to use 2 photon boards, with 1 acting as a server and the other as a client. The problem is that, in the area where the boards will be placed, there is no network coverage and therefore I’d need something like WiFi Direct to be able to send and receive data with each other. Anyone know any alternatives?

Server Photon needs to send a csv file to the client Photon.

Hi, have you tried using Boron or Electron which can connect without WIFI?

Hey, no I haven’t. I have to specifically use the Photon.
