In Bluetooth devices with simple functionality (e.g., headsets), the host stack and controller can be implemented on the same microprocessor. In this case the HCI is optional, although often implemented as an internal software interface. Low Energy Link Layer (LE LL) This is the LMP equivalent for Bluetooth Low Energy (LE), but is simpler.
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 its driver and stack to enhance what their Bluetooth device can do. Devices such as mobile phones can ...
Wi-Fi nodes often operate in infrastructure mode in which all communications go through a base station. Ad hoc mode refers to devices communicating directly with each other, without communicating with an access point. A service set is the set of all the devices associated with a particular Wi-Fi network. Devices in a service set need not be on ...
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 .
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).
BlueSoleil is a Bluetooth software/driver for Microsoft Windows, Linux and Windows CE. It supports Bluetooth chipsets from CSR, Broadcom, Marvell etc. Bluetooth dongles, PCs, Laptops, PDAs, PNDs and UMPCs are sometimes bundled with a version of this software albeit with limited functionality and OEM licensing.
Input/output. v. t. e. In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions ...
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.
