Bluetooth
Definition
A family of short-range radio standards and device profiles.
Detailed explanation
Bluetooth is a short-range radio standard for exchanging data between nearby devices. Bluetooth Classic and Bluetooth Low Energy share branding but use different connection models and profiles. Pairing establishes trust keys, while audio, HID, battery, and data profiles create separate logical services. The controller usually communicates with the host through HCI, while Windows implements much of the profile and device-container behavior. Advertising, bonding, connection, and profile activation are separate states, which is why a device can remain trusted without maintaining a continuous radio link.
