Fingerprinting Bluetooth-Low-Energy Devices Based on the Generic Attribute Profile
Guillaume Celosia, Mathieu Cunche · 2019
Bluetooth Low Energy (BLE) is a short range wireless technology included in many consumer devices such as smartphones, earphones and wristbands. As part of the Attribute (ATT) protocol, discoverable BLE devices expose a data structure called Generic Attribute (GATT) profile that describes supported features using concepts of services and characteristics. This profile can be accessed by any device in range and can expose users to privacy issues.
