JavaScript SDK for Improv Wi-Fi over BLE

Installation

You can use the JavaScript SDK by adding the following HTML to your website:

<script type="module" src="https://www.improv-wifi.com/sdk-js/launch-button.js"></script>

If you are using a bundler and JavaScript package manager, you can install the SDK via NPM:

npm install --save improv-wifi-sdk

And then import it in your code:

import 'improv-wifi-sdk';

Usage

Add the following to your website to show a button to start the provisioning process:

<improv-wifi-launch-button></improv-wifi-launch-button>

A warning message will be rendered if the browser does not support WebBluetooth.

Attributes

The following attributes are automatically added to <improv-wifi-launch-button> and can be used for styling:

Attribute Description
supported Added if this browser is supported
unsupported Added if this browser is not supported

Slots

It is possible to customize the button and the message. You do this by putting your elements inside the <improv-wifi-launch-button> element and adding the appropriate slot attribute. Use activate to replace the activation button and unsupported to replace the unsupported message:

<improv-wifi-launch-button>
  <button slot='activate'>Start provisioning!</button>
  <span slot='unsupported'>Your browser does not support provisioning.</span>
</improv-wifi-launch-button>

Events

When the state of provisioning changes, a state-changed event is fired.

A state-changed event contains the following information:

Field Description
state The current state (CONNECTING, AUTHORIZATION_REQUIRED, AUTHORIZED, PROVISIONING, PROVISIONED, ERROR, UNKNOWN)

Browser Support

This SDK requires a browser with support for WebBluetooth. Currently this is supported by Google Chrome, Microsoft Edge and other browsers based on the Blink engine.

No iOS devices are supported.
