I'd like to develop a door opener (electrical buzzer) which is activated (relay) by approaching with a previously registered (Bluetooth) phone. There should be no need of an app installed on the phone (iOS) but just a prior registration.
Ideally (maybe in a second step) I'd like to be able to check which device triggered at what time the door online (WiFi connectivity).
How do I get started? Which board is the most appropriate one?
