BLE and GATT: what a browser Bluetooth test can inspect

Bluetooth Low Energy devices expose data through services and characteristics organized by the Generic Attribute Profile (GATT).

Why it matters

How this changes a diagnosis

A compatible browser can interact with permitted BLE/GATT devices, but this does not mean it can inspect all classic Bluetooth audio or every paired device on the system.

Key points

What to remember

  • BLE/GATT is not synonymous with all Bluetooth use cases.
  • The device decides which services and characteristics it exposes.
  • Permission and browser/platform support restrict web access.
