I am thinking of creating a PWA application in VAADIN and i would like to access the Phone's bluetooth. And i dont find in their documentation any sources to do this. Is this possible?

Your help will be appreciated! Thank you!

There is some ways to do this but the browser support is limited (mostly only Chrome with Android at the moment I think). HTML5 has some specs for accessing Bluetooth or Camera.

There are some add-ons for Vaadin 10+, i.e. Flow in Vaadin Directory, which use these specs

See the links for more details.

The RapidClipse framework provides a Java mobile API that enables Vaadin developers to access to many native hardware and systems functions of mobile devices. The API uses Cordova under the hood, which is a native-browser bridge. The RapidClipse API extends Cordova with a Java API for Vaadin, that allows you to access to Cordova functions by calling Java methods, so you don't get in contact with JavaScript.

With this API have access to: Device info, device buttons, accelerometer, vibration, geolocation, compass, user contacts, local file system, barcode scanner, camera, NFC, bluetooth and allows to send SMS.

Example:

 /**
 * Add a button handler, e.g. for the back button
 */
AppService.getInstance().addBackButtonHandler(event->{
    // Do something ...
    // and consume event so that it will not be processed in the default manner by the source which originated it.   
    event.consume();
});

Supported features: http://www.rapidclipse.com/en/Framework.html

The RapidClipse framework is open source.
