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.
Version 1.6 adds optional support for wide band speech with the mSBC codec, a 16 kHz monaural configuration of the SBC codec mandated by the A2DP profile. Version 1.7 adds indicator support to report such things as headset battery level.
The Bluetooth SIG completed the Bluetooth Core Specification version 4.0 (called Bluetooth Smart) and has been adopted as of 30 June 2010. It includes Classic Bluetooth, Bluetooth high speed and Bluetooth Low Energy (BLE) protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols.
The Bluetooth asynchronous connection-oriented logical transport (ACL) is one of two types of logical transport defined in the Bluetooth Core Specification, either BR/EDR ACL or LE ACL. BR/EDR ACL is the ACL logical transport variant used with Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR, also known as Bluetooth Classic) whilst LE ACL is the ...
The technology was marketed as Bluetooth Smart and integration into version 4.0 of the Core Specification was completed in early 2010. [17] The first smartphone to implement the 4.0 specification was the iPhone 4S, released in October 2011. [18] A number of other manufacturers released Bluetooth Low Energy Ready devices in 2012.
Windows 10 (Version 1803) and later support Bluetooth version 5.0 and several Bluetooth profiles. [29] Bluetooth profiles exposed by the device but unsupported by the Windows stack will show as "Bluetooth Peripheral Device" in Device Manager.

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). [1] 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. [2]
