Im making a project were i have two robots each one with a device connected with a mobile phone. But at same time i want that, when they are near each other they exchange a unique id (so that can know the identity of the other). The best way to connect the chip to a mobile would be a peripheral-central connection right? What about the "handshaking" between the chips? Inicially i thought it would be that each one would send a beacon but now im a bit confused since they would have to send a beacon and scan for beacons... Any ideias of the best way of doing this? Thanks in advance
