BLE Device Radar

BLE Device Radar helps you discover nearby Bluetooth Low Energy (BLE) devices and inspect their advertising data in real time.

Start a scan to see nearby devices, signal strength, packet counts, device addresses, and whether devices are connectable. Explore advertised services, manufacturer data, service data, and raw advertising packets.

Save scans with custom names and find them later in History. Search saved scans and observed devices, or compare two scans to see which devices appeared, disappeared, or changed. You can also export saved scans as JSON files and import them back into the app.

Key features:

• Real-time BLE scanning

• Adjustable scan duration and RSSI threshold

• Detailed BLE advertising information

• Signal strength and packet count tracking

• Named scan history stored on your device

• Search for saved scans and observed devices

• Comparison between saved scans

• JSON import and export

• Light, dark, and system themes

Privacy:

Scan results and saved history are processed locally on your device and are not uploaded to an external server. Exported files are saved only when you choose to create them. You can delete your saved scan history from Settings at any time.

Please note:

• Bluetooth permissions are required to scan for nearby BLE devices.

• Results depend on nearby devices, their advertising behavior, signal conditions, and Android system restrictions.

• Some BLE devices use private or rotating addresses, so the same physical device may appear under different addresses over time.

• BLE Device Radar displays advertising information but does not connect to discovered devices.
