Permissions-Policy: bluetooth

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTTP Permissions-Policy header bluetooth directive controls whether the current document is allowed to use the Web Bluetooth API.

Specifically, where a defined policy disallows use of this feature, the methods of the Bluetooth object returned by Navigator.bluetooth, will block access:

Syntax

http
Permissions-Policy: bluetooth=<allowlist>;
<allowlist>

A list of origins for which permission is granted to use the feature. See Permissions-Policy > Syntax for more details.

Default policy

The default allowlist for bluetooth is self.

Examples

General example

SecureCorp Inc. wants to disable the Web Bluetooth API within all browsing contexts except for its own origin and those whose origin is https://example.com. It can do so by delivering the following HTTP response header to define a Permissions Policy:

http
Permissions-Policy: bluetooth=(self "https://example.com")

With an <iframe> element

FastCorp Inc. wants to disable bluetooth for all cross-origin child frames, except for a specific <iframe>. It can do so by delivering the following HTTP response header to define a Permissions Policy:

http
Permissions-Policy: bluetooth=(self https://other.com/blue)

Then include an allow attribute on the <iframe> element:

html
<iframe src="https://other.com/blue" allow="bluetooth"></iframe>

<iframe> attributes can selectively enable features in certain frames, and not in others, even if those frames contain documents from the same origin.
