Description

About WebBluetooth Test

Introduction

This page checks Web Bluetooth support and can show the browser’s BLE device picker. Safari and Firefox often lack this API. The page does not keep a Bluetooth data session open.

What this tool does

It reports availability and can request a device with your gesture. It does not stream sensor data or pair permanently beyond what the browser prompt does.

When to use it

Use it to confirm Chromium Web Bluetooth presence before building or troubleshooting a BLE web demo.

How it works

Supported: Chrome/Edge on many desktop and Android builds (HTTPS, BLE hardware). Unsupported: Safari and most Firefox builds. Why: Bluetooth access is sensitive and unevenly implemented. Permissions: you approve a device in the picker. Hardware: Bluetooth LE adapter and a nearby BLE device for the picker. Expected: available/unsupported, optional picker, no ongoing connection from this page.

Step-by-step instructions

  1. Open the page in Chrome or Edge with Bluetooth on.
  2. Read availability.
  3. Optionally request a device, then cancel or dismiss.

Common problems

Unsupported on Safari is common. Desktop without BLE hardware cannot discover devices.

Privacy explanation

No GATT data is read or uploaded by this tool.

Runtime principles

Built for the browser

What happens when you run this test — without downloads or accounts.

  1. 01

    Runs in your browser

    WebBluetooth Test uses standard web APIs — no install, extension, or desktop app required.

  2. 02

    Reads what the browser allows

    Results come from events and capability signals the web platform exposes for this session.

  3. 03

    Private by default

    Input and diagnostic values stay in your browser session for display — nothing is sold as media.

Troubleshooting

Common problems

Quick fixes before you dig into FAQs.

Bluetooth API missing
Web Bluetooth is mostly Chromium on HTTPS; Safari and Firefox commonly lack it. Retest in desktop Chrome or Edge.
No devices in chooser
Ensure Bluetooth is enabled, devices are advertising compatible services, and you clicked after a user gesture.
Pairing works in OS but not web
Web Bluetooth uses its own chooser path; OS pairing alone does not guarantee browser visibility.
