  • Know How to file Web Bluetooth Bugs.
  • In Chrome OS, Android, & Mac, the GATT Communication API is shipped without any flag.
  • Linux & Windows are partially implemented, but not supported. The chrome://flags/#enable-experimental-web-platform-features flag must be enabled.
  • New Windows implementation is available by running Chrome with --enable-features=NewBLEWinImplementation.
  • Root Issue 419413: Web Bluetooth and blocking issues are most authorative on status.
  • Some Bluetooth GATT operations can't be run in parallel yet. See #188 (comment)

Tip: Chrome channel releases are tracked at


  • Android: Requires Android 6.0 Marshmallow or later.
  • Mac: Requires OS X Yosemite or later.
    • Some MacBooks may not work: Check "About this Mac" / "System Report" / "Bluetooth" and verify that Low Energy is supported.
  • Linux: Requires Kernel 3.19+ and BlueZ 5.41+ installed. Read How to get Chrome Web Bluetooth working on Linux.
    • Note that Bluetooth daemon needs to run with experimental interfaces if BlueZ version is lower than 5.43: sudo /usr/sbin/bluetoothd -E
  • Windows: Requires Windows 8.1 or later.
    • To discover devices the user hasn't yet manually paired, requires Windows 10.
    • A third-party Windows 10 Polyfill (Chrome Extension + Native Executable) has been created while Windows support is not implemented yet.

Unsupported platforms

  • Android WebView: Will be supported in the future.
  • iOS: Uses the web exposed APIs as provided by the WKWebView, no implementation planned in the Chromium codebase.

Note: WebBLE is an app for iOS that supports the GATT Communication API. It was created initially for the Puck.js project.

Samsung Internet

In Samsung Internet v6.4, the GATT Communication API is shipped without any flag.
