Web Bluetooth allows us to control any Bluetooth Low Energy device directly from the browser. This allows us to target scenarios that previously could only be solved with a native app. The specification is published by the Web Bluetooth Community Group and describes an API to discover and communicate with devices over the Bluetooth 4 wireless standard. Right now, Chrome is the only major browser which currently supports this specification. With Physical Web and Web Bluetooth, we now have other avenues for getting users to interact with devices without them having to install yet another app on their phone. This is an exciting space which is worth keeping an eye on.
