This repository contains a fully functional Android application named 'Bluetooth LE Spam' that transmits crafted Bluetooth Low Energy advertisements to spoof a wide range of devices (Apple Continuity, Microsoft Swift Pair, Google Fast Pair, Samsung Easy Setup, Lovespouse) on nearby phones and tablets, triggering unwanted pop-ups and notifications. It also includes a spam detector that identifies BLE spam originating from Flipper Zeros and similar tools, running as a foreground service even on the lock screen. The application is built with Kotlin, Jetpack Compose, Material 3, Room database for persistence, and uses both legacy and modern (BLE 5) advertising modes. The codebase is well-structured around an interface-based advertisement set generator pattern and a queue handler for cycling through attacks, but it is explicitly unmaintained by the author and many exploits are patched on modern OS versions, limiting practical impact. The architecture is a standard Android single-activity app with multiple fragments and foreground services; the theme system (dynamic color, custom nav bar, status badges) demonstrates reasonable front-end craftsmanship.
The LLM identified 3 files worth highlighting for reuse:
A Kotlin interface defining a single method `getAdvertisementSets(): List<AdvertisementSet>`. All advertisement generators (Continuity, FastPair, Lovespouse, etc.) implement this interface, making it trivially extensible to add new BLE spoofing attacks. The interface has zero internal dependencies and can be extracted as a standalone pattern for any project that needs pluggable data generators.
A pure utility object that provides a function to convert a hex string (e.g., '0A1B2C') into a Kotlin `ByteArray`. It handles various formats, trims whitespace, and ensures proper parsing. No internal imports, fully reusable in any Kotlin project needing hex-to-byte conversion without external libraries.
A Jetpack Compose composable that renders a pill-shaped floating navigation bar with a blurred backdrop (using the Haze library). It supports multiple destinations, custom icons, and a smooth selected indicator. While it depends on Material 3 and Haze, the component is self-contained (imports only Compose and Haze) and demonstrates non-trivial UI craftsmanship for a custom bottom bar.
