Bluetooth® PHY, protocol, and system-level modeling

The Communications Toolbox™ Library for the Bluetooth Protocol provides standard-compliant functions and reference examples for designing, modeling, simulating, and testing the radio front-end physical layer (RF-PHY) of Bluetooth communications systems. The library supports protocol layer modeling, network modeling, link-level simulation, golden reference verification, and test waveform generation for Bluetooth low energy (BLE) and Bluetooth basic rate/enhanced data rate (BR/EDR) waveforms.

With the library, you can configure, simulate, measure, and analyze end-to-end communications links. You can modify or customize the library functions and use them as reference models for implementing Bluetooth systems and devices. The BLE functions and configuration objects support PHY and protocol layer processing, assign device roles and modes, and provide connection management services. Use library features and examples to generate and decode Bluetooth BR/EDR waveforms. Use the BLE direction-finding functions and objects to estimate angle of arrival (AoA) and angle of departure (AoD). The library provides functions to write generated and recovered BLE link layer packets to packet capture (PCAP) and packet capture next generation (PCAPNG) files.

The library includes reference examples to help you model the behavior of Bluetooth devices or a network of Bluetooth devices. Adapt the provided reference designs to explore communication in multinode networks and to study the system performance of your designs. The library includes BLE mesh network reference examples to study network layer flooding and energy profiling. Use library features and examples to help you model and analyze interference from and co-existence with other networks.
