Question 1

Does Web Bluetooth work in Safari?

Accepted Answer

Yes — with the beacio Safari extension installed, navigator.bluetooth works in the real Safari you already use on iPhone and iPad: same URL bar, bookmarks, history and Add to Home Screen, not a separate browser. The extension uses SafariWebExtensionHandler with full CoreBluetooth access to bridge the Web Bluetooth API, and pages run under a genuine Safari user-agent so sites that sniff for an unsupported browser still work. Install from the App Store and enable in Safari settings. Your existing Web Bluetooth code works unchanged.

Question 2

Is beacio a separate browser app?

Accepted Answer

No. beacio is a Safari extension, not a separate browser. Your Web Bluetooth site opens in the real Safari you already use — keeping the URL bar, bookmarks, history, autofill and Add to Home Screen — and reports a genuine Safari user-agent, so sites that reject unknown browsers still load. The standard polyfill is free, so you can confirm your own specific BLE device connects before integrating or paying for anything.

Question 3

How do I use Bluetooth in a web app on iPhone?

Accepted Answer

Install the beacio Safari extension, then use the standard Web Bluetooth API (navigator.bluetooth.requestDevice) — the same code you already ship to Chrome. One line of code: import '@beacio/core/auto' — this polyfills navigator.bluetooth on Safari iOS and is a no-op on Chrome/Edge where it's already supported.

Question 4

Can Safari extensions access Bluetooth?

Accepted Answer

Yes. Safari Web Extensions on iOS use SafariWebExtensionHandler, which runs as a native iOS process with full access to CoreBluetooth. This allows the extension to scan for, connect to, and communicate with BLE devices, then relay data to web pages via the extension messaging API.

Question 5

Is beacio compliant with the W3C Web Bluetooth specification?

Accepted Answer

Yes. beacio implements the full W3C Web Bluetooth specification and was verified against it section by section: every interface member — requestDevice, GATT server, services, characteristics, descriptors, BluetoothUUID, advertising events, and event bubbling — was traced to the normative spec text, with filter validation, permission grants, the GATT blocklist, and per-origin device IDs enforced in the native layer. The full interface-by-interface conformance matrix is published at https://beacio.com/docs-md/conformance.md.
