Build a Bluetooth app with the Chrome Web Bluetooth API

Browsers are rapidly evolving with new APIs like the Web Bluetooth API, which, although still in beta, promises to open numerous possibilities for developers seeking to use Bluetooth without building native apps for each platform. This experimental API allows a simple web page to pair with devices such as phones, retrieving data like battery percentage and device information through JavaScript. However, there are limitations due to varying browser support and device restrictions. The tutorial explains using the API with a basic HTML setup and JavaScript code, emphasizing the importance of understanding different devices' Bluetooth services and characteristics. While the API is not yet widely supported, gaining early expertise can provide a competitive advantage and offer opportunities for creating Bluetooth-related web services, as the technology becomes more accessible to developers.
