Work is in progress:

  • Notes updated 2017-02-15.
  • Know How to file Web Bluetooth Bugs.
  • The chrome://flags/#enable-experimental-web-platform-features flag must be enabled on Linux. In Chrome OS, Android, and Mac, the GATT Communication API is available without any flag.
  • 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, 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.
    • To discover devices the user hasn't yet manually paired, requires Windows 10.

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.
