Link Management Protocol (LMP) is designed to ease the configuration and management of optical network devices. Such devices may be interconnected by thousands of data-bearing links, which are aggregated into a smaller number of traffic engineering (TE) links.

The Link Manager carries out link setup, authentication, link configuration and other protocols. It discovers other remote LM’s and communicates with them via the Link Manager Protocol (LMP). To perform its service provider role, the LM uses the services of the underlying Link Controller (LC).

L2CAP is used within the Bluetooth protocol stack. It passes packets to either the Host Controller Interface (HCI) or, on a hostless system, directly to the Link Manager/ACL link. L2CAP’s functions include: Multiplexing data between different higher layer protocols.

What is the latest version of Bluetooth?

Bluetooth® has long been the industry standard for streaming audio applications and audio devices. At the CES conference in January 2020, Bluetooth introduced the latest version of Bluetooth technology — version 5.2. Version 5.2 offers new benefits for the next generation of wireless devices and audio technologies.

What is the best version of Bluetooth?

This is partially in thanks to the release of Bluetooth 5.0 back in 2016, which has become the new standard for wireless tech. All our best sellers in the true wireless category use 5.0, which can transmit eight times more data, at four times the distance, and twice the speed of the previous version, Bluetooth 4.2.

The Bluetooth link layer outlines the way Bluetooth devices can use the raw transmission facility given by the radio layer to exchange information. The functions of the link layer is very close to MAC (medium access control) sublayer of the OSI model.

The Link Manager is responsible for setting up and managing the baseband connections that link Bluetooth devices. The Link Manager establishes ACL links by controlling the baseband; then LMP messages can be used to establish a SCO (voice) link across an exist- ing ACL connection.

What is Bluetooth and its architecture?

Bluetooth network technology connects mobile devices wirelessly over a short-range to form a personal area network (PAN). The Bluetooth architecture has its own independent model with a stack of protocols, instead of following the standard OSI model or TCP/IP model.
