## What is WebBLE?

Very simple web browser that supports an initial subset of  the web bluetooth javascript APIs, with bookmarks and console log viewing support.

*** New in 1.7 ***

- support for pybricks

*** Overview ***

Using this app you can navigate to a site written in javascript that can interact with your bluetooth (low energy) devices. This allows you to write your applications for use with devices such as puck.js in a language you are more familiar with (i.e. javascript) and be able to use it from your iOS device.

Use the built-in console viewer to debug issues when running your site on WebBLE.

Security is important for bluetooth device access, and so only sites that use https are supported, and it is not possible to connect to a bluetooth device without permission being granted by the user.

Initially the following key APIs are supported:

- bluetooth.requestDevice()
- bluetooth.getAvailability()

- BluetoothDevice.gatt
- BluetoothDevice.addEventListener('gattserverdisconnected', cb)

- BluetoothRemoteGATTServer.connect()
- BluetoothRemoteGATTServer.disconnect()
- BluetoothRemoteGATTServer.getPrimaryService()

- BluetoothRemoteGATTService.getCharacteristic()

- BluetoothRemoteGATTCharacteristic.writeValue()
- BluetoothRemoteGATTCharacteristic.writeValueWithResponse()
- BluetoothRemoteGATTCharacteristic.writeValueWithoutResponse()
- BluetoothRemoteGATTCharacteristic.readValue()
- BluetoothRemoteGATTCharacteristic.startNotifications()
- BluetoothRemoteGATTCharacteristic.stopNotifications()
- BluetoothRemoteGATTCharacteristic.addEventListener("characteristicvaluechanged", cb)

## Key features

- Web Bluetooth JavaScript API support
- Bookmarks
- Console log viewer
- HTTPS site support
- User permission for Bluetooth
- Pybricks support

### 5/5 — Brilliant - It works

*2026-06-07, version 1.7.0*

Great Bluetooth web browser, that respects your privacy. It’s basic but it works great. It would be very helpful if file downloads were supported but unfortunately they don’t seem to work. Uploads work. 
This app is well worth downloading.

### 5/5 — Thank you!

*2026-03-09, version 1.7.0*

Really helpful especially thank you for sharing the code as well, a very interesting topic!

### 1/5 — DO NOT PAY FOR THIS

*2025-09-18, version 1.7.0*

It rarely works for connecting my Bangle JS. You can’t clear the cache. Navigation is horrible. You have to type in the entire url exactly.

### 1/5 — iOS user? Save your $2.

*2025-04-19, version 1.7.0*

This app is garbage. It locked up immediately upon opening it. There is no instruction or navigation. All I see is the Developer’s bio and a Bluetooth abstract. The app doesn’t connect to Bluetooth on the iPhone 16 series at all.
If you’re still using your iPhone 13, this app might work.

### 5/5 — Simple, works for me

*2025-04-08, version 1.7.0*

Happy bangle JS user.

### 2/5 — Values input

*2024-10-17, version 1.7.0*

The same issue!

### 1/5 — It does not work with Ozobot

*2024-09-06, version 1.7.0*

For me it is worthless.

### 4/5 — Values input

*2024-03-20, version 1.7.0*

Dear Developers , Thank you for this tool somehow it is working with pybricks but there is one issue , I can not change values in block mode over iPad. Any idea what this can be ? Can you support ? Thank you. Seb

### 4/5 — Works great

*2024-03-17, version 1.7.0*

I used this for a personal project; works great and as expected.

### 4/5 — No Voice Recognition

*2024-02-19, version 1.7.0*

This app is almost perfect, just voice regognition is not supported (other browsers do support it).

- bigger touch area at the bottom of the screen to show the bars when they are hidden
- console now animates into view, and extends to the bottom of the screen not just the safe area
- user agent string tweaked to convince more website browser checkers that WebBLE behaves just like Safari for most use cases

- couple other of minor bug fixes

### 1.5.0 — 2022-03-28

Features:

Support for the getPrimaryServices() method on device.gatt

Bug fixes:

- Issue 28: device disconnected unexpectedly on passing a TypedArray view on a very large ArrayBuffer (caused by ignoring the limits from the TypeArray view).
- fixes a potential crash when a navigation occurrs (including a refresh) while the bluetooth device picker is visible

### 1.3.1 — 2020-10-19

Support for the web Geolocation APIs
