In this paper, we present a customer preference analysis system using the Bluetooth Low Energy technology.
Compared to Classic Bluetooth, Bluetooth Low Energy provides considerably reduced power consumption, and
cost, as well as some unique characteristics while maintaining a similar communication range. The customer
preference analysis system collects nearby Bluetooth Low Energy devices using an Android mobile device via
Bluetooth Low Energy. In addition, the system is capable of suggesting, and advertising products that are related to
these Bluetooth Low Energy devices based on the name of their manufacturer. This feature aims to attract potential
customers to purchase these products.
