Bluetooth Library: Simulate, Design, and Test Bluetooth Systems in MATLAB

Houman Zarrinkoub, PhD., MathWorks

Communications Toolbox™ Library for Bluetooth^® Protocol provides standard-compliant functions and reference examples for the design, modeling, simulation, and testing of Bluetooth communications systems. The library supports protocol layer modeling, network modeling, link-level simulation, golden reference verification, and test waveform generation.

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 library provides reference examples to help you model the behavior of Bluetooth devices or a network of Bluetooth devices. Adapt the reference designs provided to explore communication in multi-node networks and study the system performance of your designs. Using the Bluetooth library, you can model and analyze interference from other networks and co-existence with other networks.

Slide 1

This video introduces the Communications Toolbox Library for the Bluetooth Protocol, a library of MATLAB functions and reference designs enabling you to model, simulate, and test Bluetooth communications systems.

Slide 2

Bluetooth Library is a free downloadable add-on to Communications Toolbox, allowing you to model the behavior of Bluetooth devices or a network of Bluetooth devices.

It is available with R2019a release of MATLABand focuses on Bluetooth Low Energy (BLE).

Its functionality is compliant with Bluetooth 5.0 and 4.x and covers all the layers of BLE stack.

Slide 3

Bluetooth is the fifth standards capability in the lineup of wireless standard-based solutions offered by MathWorks.

Beside Bluetooth add-on, we also have another Communications Toolbox add-on supporting ZigBee and WPAN standards, and we have standalone products for 5G, LTE, and WLAN standards.

Slide 4

You can use the Bluetooth Library for

Bluetooth Low Energy (BLE) PHY layer simulation and analysis, including:
- Waveform generation and visualization
- Signal recovery and analysis
- End-to-end simulation
Bluetooth protocol stack and network layer analysis and simulation
- BLE channel selection algorithms
- BLE devices connection procedure
- BLE network co-existence with WLAN interference
- Applications such as Heart Rate Profile (HRP)
Work with over-the-air signals using Pluto SDR hardware with:
- BLE signal transmission over a channel
- BLE signal capture over a channel
- Performing receiver operations to decode the BLE signal

Slide 6

With Bluetooth Library, you can:

Decode the BLE received waveforms with distortions from RF front-end impairments and AWGN channels
Perform receiver operations including time, frequency, and phase synchronization
Compute performance measures such as BER and PER
