BLE Sniffer scans and captures nearby Bluetooth Low Energy devices — logging advertisements, mapping proximity, and giving you the raw data. Built for hardware security research and privacy sweeps.
Available now on Android and iOS
// Capabilities
A focused tool for the RF-curious.
Scan & capture
Scan for nearby Bluetooth Low Energy devices that are broadcasting and capture their advertisement data — name, address, RSSI, manufacturer, and service UUIDs.
Log offline, export CSV
Every scan session is logged on-device for offline analysis. Export to CSV whenever you want the raw data in your own hands.
Proximity radar
An RSSI-based radar visualizes how close each device is, so you can sweep a room and home in on a signal.
No ads. No telemetry.
No accounts, no in-app purchases, and no advertising, analytics, or crash-reporting code. The app sends nothing over the internet — no servers, no cloud, no third-party services — so your data stays on your phone unless you choose to export or share it.
// Use cases
Built for two jobs.
BLE Sniffer is the Bluetooth equivalent of a raw-capture tool — passive by default, yours to analyze.
Hardware security research
Enumerate devices, inspect advertisement payloads, and watch how hardware behaves over the air — then export it for deeper analysis.
Personal BLE audits
Walk a space — your home, an office, a rental — and use the proximity radar to see which Bluetooth Low Energy devices are broadcasting nearby and roughly how close they are. It surfaces BLE advertisements only; it can't detect devices that don't broadcast Bluetooth.
Your data stays on your device.
The BLE Sniffer app has no accounts, no cloud, and no advertising, analytics, or crash-reporting code. It sends no data over the internet — no servers, no third-party services — so your scan logs live on your phone until you delete them, and nothing leaves the device unless you choose to export or share it. This website is operated separately and stores only what you send through the contact form (plus standard server logs); see the Privacy Policy for details.
