During the last few years, we have seen a tremendous increase in Internet of Things (IoT) devices  as well as devices that turn ordinary objects into smart objects. An example of this is the newly released Apple AirTags  which use a combination of Bluetooth Low Energy (BLE) and Ultra-wide Band (UWB)  to localize and track any attached objects. In addition to raising new research opportunities in indoor localization and home automation, it also raises a multitude of security questions in terms of privacy and the possible abuse of AirTags as spyware/stalkerware . Therefore, it is of high interest to detect such devices through their wireless data exchange readily.
Thesis Question: How to detect a hidden/not-paired Apple AirTag utilizing a smartphone?
This would initially involve a short research period to identify technologies and libraries  that could be integrated to detect BLE traffic on iOS and Android devices. Followed by the development of a prototype application, either on an iOS or Android device, that uses the smartphone's integrated BLE sensing capabilities to detect active devices within its vicinity, similar to the BLE Scanner 4.0 App by Bluexpixel Technologies LLP. The third step would then pertain to identifying Apple AirTags among the detected BLE devices.
Optional: The implementation of a check to detect whether the used phone has UWB capabilities.
