I have particle photon already and was wondering how I can use it as a gateway so I don’t have to buy a gateway shield. I found a gateway.ino file on the particle IDE but I would think you have to have some communication between the 2. What pins on the photon and bluz need to be linked together?
Also, after flashing bluz I want it to be a solitary device not connected to the cloud, only locally connected to a phone app. Does it always need to communicate with the cloud?
