Web Bluetooth · GATT

BLE Analyzer

Scan for real Bluetooth Low Energy hardware near you and walk its live GATT profile - advertised services, characteristics, and descriptors - straight from the browser. Nothing is simulated; every UUID below comes off the device you choose.

How it works

Trigger a scan

Hit scan. The browser opens its native device chooser - your selection is the only device this page can ever see.

Connect over GATT

On pick, it connects to the device's GATT server and enumerates every primary service it's willing to share.

Walk the tree

Expand a service to reveal its characteristics, their properties, and nested descriptors. Read any readable value as live hex and UTF-8.

Everything runs locally in your browser. No device data is uploaded, stored, or sent anywhere.
