Personal BLE trackers are handy for finding your keys and dangerous when used to follow a person through a crowded station. Earlier binary detectors (tracker vs not) break down in dense, heterogeneous environments. This paper introduces a categorical classifier that identifies popular BLE trackers and their operational states from a 200-hour dataset, reaching over 99% accuracy and validated live in a busy central station. A vendor-agnostic step toward robust, real-world anti-stalking detection.
