Description [link]

This header defines Network Layer API for Link-Layer Control Protocol.

LLCP takes care of most aspects of the out-of-band communication of BLE:

connection parameters negociation and updates,
channel mapping,
encryption setup,
link termination.

To this extent, LLCP layer needs to communicate with:

physical layer (for updating connection parameters and channels),
link layer (for enabling / disabling cryptography),
Security DB (for key lookup),

LLCP is expected to be bound on a link layer.

There is a generic implementation of this layer in the library that can be created through ble_llcp_create.
