Bluetooth Low Energy · Scanner
See every
BLE signal
in the room.
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.
Coming soon to iOS & Android
// Capabilities
A focused tool for the RF-curious.
Scan & capture
Discover every nearby Bluetooth Low Energy device and capture its 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, no tracking. Nothing leaves your phone. The app works for you and only you.
// 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.
Privacy sweeps
Walk an unfamiliar space — a rental, a hotel room — and use the proximity radar to find Bluetooth devices that shouldn't be there.
Your data never leaves your device.
BLE Sniffer collects nothing. No analytics, no accounts, no cloud. Scan logs live on your phone until you delete them. This website is the same — it stores only what you choose to send through the contact form.
