Protocol Components

Functions, configuration objects, and System objects for Bluetooth® protocol layers above the PHY

Communications Toolbox™ Library for the Bluetooth Protocol provides functions and System objects to model Bluetooth link layer (LL), logical link control and adaptation protocol (L2CAP), generic access profile (GAP), and attribute protocol (ATT). Format configuration objects are used to parameterize these functions and to create Bluetooth protocol data units (PDUs) that are compliant with the Bluetooth Core Specifications.

Link Layer State Machine for BLE Devices using Stateflow

Link Layer State Machine for BLE Devices using Stateflow

Model link layer state machine to establish a connection between Bluetooth® low energy (BLE) devices using the Communications Toolbox™ Library for the Bluetooth Protocol and Stateflow®. The working mechanism of the link layer is described in terms of a state machine consisting of these five states: Standby, Advertising, Scanning, Initiating, and Connection. Based on these states, the Bluetooth devices can either be Advertisers, Scanners, Initiators, Master or Slave. This example presents a model to demonstrate the connection establishment process between a Master and a Slave through transitions between different states of the link layer state machine. The simulation results display the time taken to establish a connection between a Master and a Slave. Moreover, this example also provides plots showing the variation in connection establishment time as a function of configuration parameters such as advertising interval and interference.
