The Bluetooth-enabled Bracelet and peripherals have brought tremendous convenience to our daily life. Over the last few years, Bluetooth beacons have also been gaining popularity in implementing a variety of innovative location-based services such as self-guided systems in exhibition centers. Although, the broadcast-based beacon technology can only offer unidirectional communication. In case bracelet users would like to respond to the beacon messages, they have to rely on their mobile Internet connections to send the information back to the backend system.
