Benefits to higher bluetooth versions1/23/2024 ![]() Today, we’re excited to announce that a new study guide known as The Bluetooth LE Primer has been released. They’re referred to as study guides, and they cover both the theory and hands-on practical implementation issues of the technology in general and as it appears on various popular platforms. The Bluetooth Special Interest Group (SIG) has created a collection of educational resources aimed at assisting technical professionals to ascend the learning curve associated with Bluetooth LE. If you’re new to Bluetooth ® Low Energy (LE) and want to understand its constituent parts, features, and how it works, where’s the best place to start? This is a large topic and the primary reference specification, the Bluetooth Core Specification, is a substantial and formal document and not necessarily an optimal place for a beginner to start learning. Getting Started with Bluetooth Low Energy This was a new version of Bluetooth ® technology, which rather than replace its predecessor, Bluetooth BR/EDR, sat alongside it as an alternative with capabilities and qualities that made it perfect for a new generation of products and the ability to meet new and challenging technical and functional requirements. It offered a raw data rate of 2 mb/s but was still designed for use cases involving two devices exchanging data directly between them.īluetooth Low Energy (LE) first materialized in version 4.0 of the Bluetooth Core Specification. Later, a faster version of Bluetooth technology known as Bluetooth BR/EDR (Enhanced Data Rate) was defined. It offered a raw data rate at the physical layer of 1 million bits per second (1 mb/s). This first version of Bluetooth technology, used in those very first ever Bluetooth products, is known more formally as Bluetooth BR (Basic Rate). The latter is an audio product, and audio proved to be the killer app for this original version of Bluetooth technology. Initially created to allow two devices to exchange data wirelessly without the need for any other intermediate networking equipment, it quickly found a role in products such as wireless mice and hands-free kits for cars. Bluetooth ® technology has been around for more than 20 years.
