Add your Bluetooth Low-Energy tags/devices to your list, give a name toeach one, and later youll be able to run a scan and find which tags arestill around and which ones are missing (or not broadcasting).For example, if you are a tour guide, and your group of tourists isleaving the bus for some free time, after which youll have to make surethat everyone has returned. Just give each tourist a smart Bluetoothbutton (that you added to the app beforehand), and when the time comes,tell everyone on the bus to press their button, and you could easily findout if anyone is missing.To add more than 7 tags, you will have to purchase a subscription.
