Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).

That's great news if you own a pair of AirPods.
Radio frequency communication (RFCOMM) The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port ...
SBC, or low-complexity subband codec, is an audio subband codec specified by the Bluetooth Special Interest Group (SIG) for the Advanced Audio Distribution Profile (A2DP). SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers. It can also be used on the Internet.
Standard. ETSI TS 103 634. LC3 ( Low Complexity Communication Codec) is an audio codec specified by the Bluetooth Special Interest Group (SIG) for the LE Audio audio protocol introduced in Bluetooth 5.2. [1] It's developed by Fraunhofer IIS and Ericsson as the successor of the SBC codec. [2]
The Windows 7/Vista/8/10 stack provides kernel-mode and user-mode APIs for its Bluetooth stack- so hardware and software vendors can implement additional profiles. Windows 10 (Version 1803) and later support Bluetooth version 5.0 and several Bluetooth profiles. Bluetooth profiles exposed by the device but unsupported by the Windows stack will ...
