# BLE-Research-Group/MetaRadar

A tool for BLE environment monitoring. Find and track Bluetooth devices around, create custom filters, get notified when the BLE fingerprint you are looking for is around.

## What it is
MetaRadar (BLE Radar) is an Android application for monitoring Bluetooth Low Energy environments. It scans for nearby BLE devices, analyzes their advertising packets to identify trackable vs privacy-protected devices, and alerts users when suspicious or persistent devices are detected.

## Use cases
- find and track bluetooth devices around me
- detect airtags or trackers following me
- check which ble devices can be used to track me
- get notified when a specific bluetooth device is nearby
- scan ble advertising packets for security research
- identify devices with randomized vs persistent mac addresses

## When to choose
- you need an on-device BLE scanner with custom filters and alerts on Android
- you are doing security or privacy research on BLE tracking
- you want early warning against stalking via Bluetooth trackers

## When to avoid
- you need BLE scanning on iOS, desktop, or non-Android platforms
- you need to actively connect to or control BLE peripherals rather than passively monitor them
- you need a general-purpose Bluetooth management tool for pairing devices

## Facets
- artifact type: application
