A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack. Bluetooth stacks can be roughly divided into two distinct categories: General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers .
The host stack is generally implemented as part of an operating system, or as an installable package on top of an operating system. For integrated devices such as Bluetooth headsets, the host stack and controller stack can be run on the same microprocessor to reduce mass production costs; this is known as a hostless system.
Bluetooth protocol stack. Bluetooth is defined as a layer protocol architecture consisting of core protocols, cable replacement protocols, telephony control protocols, and adopted protocols. [134] Mandatory protocols for all Bluetooth stacks are LMP, L2CAP and SDP.
For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies. A host operating system can expose a basic set of profiles (namely OBEX, HID and Audio Sink) and manufacturers can add additional profiles to their drivers and stack to enhance what their Bluetooth devices can do. Devices such as mobile phones can ...
Bluetopia, the company's core product, was their implementation of the upper layers of the Bluetooth protocol stack. Bluetopia was first qualified by the Bluetooth Special Interest Group in 2000 and since had been used by Original Equipment Manufacturers (OEMs) and Original Design Manufacturers (ODMs) around the world in personal computing ...

Other key features include Bluetooth capability, hands-free calling for iPhone users, and an easy-to-use app with a “find my hearing aid” feature. There are nine models to choose from with BTE ...
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 ...
