Question

Answer 1

You can't send message to other via beacon device. Do you have beacon device in store? If Yes, your app must installed in user device which is also in foreground while they entered into your store. So while your beacon device broadcasting, your app can detect accurately where they are. and your app must do some calculation based on location(use triangle theory). Send this information to your server, they will send information to your customer. For example, if your customer now in center of your store, you can popup ads with product image(Flat 50% offer...)

See this apple's doc to learn more about beacon.

Answer 2

I beacons are not two way communication devices, they are low powered bluetooth devices that advertise some specific info. So it's only one way. There are only two modes of operations for a beacon , as region-monitoring and ranging.
