Chrome

Work is in progress:

Notes updated 2017-06-09.
Know How to file Web Bluetooth Bugs.
The chrome://flags/#enable-experimental-web-platform-features flag must be enabled on Linux and Windows. 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)

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.

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.

Same as Chrome unless specified otherwise
