simondankelmann/Bluetooth-LE-Spam — reverse-engineered prompt

Build me an Android app for Bluetooth Low Energy research that can send phantom BLE advertisements from a phone, similar to the Flipper Zero idea, but with a simple friendly interface. It should work on Android 8 and newer, explain the required Bluetooth and location permissions clearly, and include safety warnings that it is only for testing on my own devices.

I want a main screen where I can choose advertising targets like Apple device pop ups, Microsoft Swift Pair, Samsung Easy Setup, or all supported services, then start and stop the broadcast easily. Add basic controls for repeat mode, advertising interval, and signal power if Android allows it.

Also include a spam detector mode that scans nearby BLE activity in the background and sends a notification when it sees suspicious spam, without collecting location data. Make it clean enough to build as an APK and easy to test. Look up current Android BLE docs online if you need to.
