I want to build a PWA with capability to connect with "regular" bluetooth, not with Bluetooth Low Energy (BLE). Is that possible ?
The Web Bluetooth API currently only supports the GATT (Generic Attribute Profile) portion of the Bluetooth specification, which is primarily used by Bluetooth Low Energy devices. It does not support other Bluetooth profiles.
My team maintains the Web Bluetooth specification and its implementation in Chromium-based browsers as well as work on bringing new capabilities to the web. What type of Bluetooth Classic device are you interested in integrating with a PWA?
