PerliBlue

See every Bluetooth device around you

A Bluetooth scanner for people who want to know what is actually in the air around them. It lists every Low Energy and Classic device it can hear, decodes the raw advertisement byte by byte, walks the GATT tree and helps you find what you have lost. Scanning needs no network, no account and no sign-in.

Coming soon to Google Play for Android. There is a Linux desktop version too.

What it does

  • One live scan list

    Bluetooth Low Energy and Classic together, with signal strength, estimated distance, the company behind the address and a sparkline for every device.

  • Every advertisement decoded

    iBeacon, Eddystone and AltBeacon, plus BTHome, Ruuvi, Xiaomi, Govee, Apple, Microsoft and Google Fast Pair payloads, with the raw hex to copy.

  • GATT explorer

    Connect, walk every service, characteristic and descriptor with their SIG names, read and write values, and watch notifications arrive live.

  • Find it again

    A full-screen proximity view with beeps and haptics that quicken as you get closer. Star a device and see when it arrives or goes out of range.

  • Tools and export

    Adapter details, a UUID and company lookup, a packet-level session recorder, and CSV or JSON export of a whole scan.

  • Private by design

    Nothing you scan is uploaded. There is no account and no sync, and what you record stays on the device until you share it yourself.
