The embedded world Exhibition & Conference is the world’s premier event on the embedded systems topic. It brings together researchers and developers, industry and academia from all disciplines of embedded system development and drives the development of complex systems of systems and its manifold innovative aspects.
The Bluetooth SIG will host two tracks during the conference focused on Bluetooth® technology.
Participating Sessions:
Presenter: Damon Barnes, Bluetooth SIG
Date and Time: 13 March, 9:30 CEST
Description:The Bluetooth SIG typically has more than 50 active specification development projects at any given time. These projects include everything from adding minor features to existing Bluetooth specifications to creating new specifications that add major functionality to Bluetooth wireless technology. In this presentation, Damon Barnes will provide an overview of the latest Bluetooth technology roadmap, including new details on the High Data Throughput, Ultra Low Latency HID, and Higher Bands projects.
Presenter: Donatien Garnier, Blecon
Date and Time: 13 March, 10:00 CEST
Description: Bluetooth, renowned for its cost-effectiveness and ubiquity, is a compelling choice for IoT connectivity, powering numerous successful IoT products. This session discusses the proven solutions and best practices employed by IoT products built on top of core Bluetooth technology, while also highlighting common pitfalls to avoid.
Donatien Garnier, Co-Founder of Blecon, will guide attendees through the process of leveraging Bluetooth to enable IoT connectivity for a new generation of devices. The talk will encompass:
1. Navigating Challenges and Opportunities: Gain insights into typical architectures that can be constructed on top of Bluetooth to facilitate cloud connectivity, with a particular emphasis on network topology, security, and the associated trade-offs.
2. Real-world Impact: Explore case studies that showcase the power of Bluetooth IoT across a diverse range of industries.
Attendees will discover why they should consider Bluetooth for IoT device connectivity, particularly in scenarios where alternative technologies may not be viable. This session is ideal for developers, engineers, and technology enthusiasts eager to harness Bluetooth for next-generation IoT solutions.
Presenter: Gerhard Willbold, Microchip Automotive
Date and Time: 13 March, 10:30 CEST
Description: When establishing a connection with a new Bluetooth Low Energy (LE) peripheral device, the conventional approach involves disconnecting and then reconnecting, resulting in periods of inactivity where communication is not possible. This limitation makes Bluetooth unsuitable for applications, such as car access or real-time industrial, where a central device moving across a large area needs to maintain a continuous connection with peripheral devices. To use Bluetooth in these applications, the connection from the Bluetooth LE central device needs to switch seamlessly from one Bluetooth LE peripheral device to the next creating a continuous connection.
To address this issue, a handover algorithm can be employed to maintain the connection when switching between a Bluetooth LE central device and multiple peripheral devices. This algorithm would be implemented through an extension of the Bluetooth LE Host Controller Interface (HCI) using vendor-specific commands. During the handover process, the central device remains continuously connected to the preferred peripheral device without interruption.
This presentation will delve into the Bluetooth handover algorithm developed for Microchip’s PIC32CX-BZ and WBZ multi-protocol wireless microcontroller (MCU) devices. It will begin with a brief technical overview of the MCUs in use, followed by details on the application states (synchronization and connection switching) and necessary communication with the host application and controller.
Presenters: Charlie Ice, NXP Semiconductors
Date and Time: 13 March, 11:45 CEST
Description: The new Bluetooth Channel Sounding standard promises to improve both accuracy and security, and many of the published numbers are very enticing. However, achieving these numbers in real-world use cases is difficult using a single antenna. By adding a second antenna, the channel sounding accuracy improves dramatically. In this session, we will discover the hardware requirements and antenna design basics for dual antennas for channel sounding and then look at how a distance estimation algorithm uses the data from the second antenna.
Presenter: Arne Bestmann, Lambda:4 Entwicklungen
Date and Time: 13 March, 12:15 CEST
Description: The latest (Sep. 2024) Bluetooth Core Specification v6 adds a major new feature Channel Sounding to the Bluetooth ecosystem. It will improve distance estimation with Bluetooth considerably. RSSI based systems have carved out a market niche for themselves, but are often not reliable and accurate enough. This is where Channel Sounding comes into play. It provides a robust and accurate way to estimate the distance between two Bluetooth devices. Since the Bluetooth standard just provides raw IQ data, algorithms are needed to calculate a distance based on the provided data. The algorithm is the most important piece when looking at the performance. There are several factors that play an important part in the performance of Channel Sounding systems. On the one hand that is the environment. Things like reflections, multipathing, interferences from other technologies on the same band need to be compensated for by the algorithm. Is it an application that works within line-of-sight or non-line-of-sight? But there are also factors that can be addressed when designing a Channel Sounding system for a specific use case.
Presenter: Damon Barnes
Date and Time: 13 March, 12:45 CEST
Description: Bluetooth Channel Sounding was released to the public as part of Bluetooth Core Specification v6.0. Bluetooth Channel Sounding is a new secure, fine ranging feature that brings true distance awareness to Bluetooth connected devices. True distance awareness enables Bluetooth connected devices to better understand their position in relation to each other, which has the potential to enhance the convenience, safety, and security of many Bluetooth applications.
Since the release of Bluetooth Channel Sounding, there has been significant market interest and notable product implementation momentum. In this presentation, Damon Barnes, Director of Technical Marketing at the Bluetooth SIG, will provide a technical overview of the Bluetooth Channel Sounding feature and share updates on the rollout to the public, including product support, the latest performance testing, and leading use cases.
