I have read that I'll need a WiFi router as well but am hoping there is a way around this.
Maybe something like what is mentioned in this thread?
"the Broadcom BCM43362 chip which the Photon is based on does support Wi-Fi Direct mode (will require firmware changes) that will allow you to connect between two photons , however that will be point-to-point type communication, not really mesh type."
I am actually using the Electron right now for the GSM module, but this is connected via breadboard to the receiving Photon. I cannot find any documentation or comment from Particle that it is indeed possible to have 2 photons connect without a WiFi router. All I can find is comments that say it is possible via softAP/Wifi Direct as of last September (intended release date). Do you know of any threads that confirm or deny this?
