==== Link Manager ====
The Link Manager (LM) is the system that manages establishing the connection between devices. It is responsible for the establishment, authentication and configuration of the link. The Link Manager locates other managers and communicates with them via the management protocol of the LMP link. To perform its function as a service provider, the LM uses the services included in the Link Controller (LC).
The Link Manager Protocol basically consists of several PDUs (Protocol Data Units) that are sent from one device to another. The following is a list of supported services:
* Transmission and reception of data.
* Name request
* Request of the link addresses.
* Establishment of the connection.
* Authentication.
* Negotiation of link mode and connection establishment.
