Packetcraft is a member of Bluetooth SIG, "a global community of over 36,000 companies serving to unify, harmonize and drive innovation in the vast range of connected devices all around us.
Through collective creation and shared technical standards, Bluetooth® technology simplifies, secures and enriches the technology experience of users worldwide."
We have included SIG's enormous collection of resources regarding bluetooth and the vision for the technology here for quick reference but highly recommend visiting their website and utilizing their range of market research, technology details, qualifications and specs as well as application and imagination of bluetooth technology that is on the horizon. We are proud to be part of this enormous community of innovators who value connectivity and drive the global market forward with excellence.
With over 4 billion products shipping per year, Bluetooth® technology is the global standard for simple, secure wireless connections. Since its formation in 1998, the Bluetooth community has continued to expand the capabilities of Bluetooth — powering innovation, creating new markets, and redefining communication worldwide. Today, Bluetooth is the wireless technology of choice for developers in many solution areas, including audio streaming, data transfer, location services, and large-scale device networks.
One key reason for the incredible success of Bluetooth® technology is the tremendous flexibility it provides developers. Offering two radio options, Bluetooth technology provides developers with a versatile set of full-stack, fit-for-purpose solutions to meet the ever-expanding needs for wireless connectivity.
Whether a product streams high-quality audio between a smartphone and speaker, transfers data between a tablet and medical device, or sends messages between thousands of nodes in a building automation solution, the Bluetooth Low Energy (LE) and Bluetooth Classic radios are designed to meet the unique needs of developers worldwide.
The Bluetooth Classic radio, also referred to as Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), is a low power radio that streams data over 79 channels in the 2.4GHz unlicensed industrial, scientific, and medical (ISM) frequency band. Supporting point-to-point device communication, Bluetooth Classic is mainly used to enable wireless audio streaming and has become the standard radio protocol behind wireless speakers, headphones, and in-car entertainment systems. The Bluetooth Classic radio also enables data transfer applications, including mobile printing.
Bluetooth® Low Energy (LE)
The Bluetooth Low Energy (LE) radio is designed for very low power operation. Transmitting data over 40 channels in the 2.4GHz unlicensed ISM frequency band, the Bluetooth LE radio provides developers a tremendous amount of flexibility to build products that meet the unique connectivity requirements of their market. Bluetooth LE supports multiple communication topologies, expanding from point-to-point to broadcast and, most recently, mesh, enabling Bluetooth technology to support the creation of reliable, large-scale device networks. While initially known for its device communications capabilities, Bluetooth LE is now also widely used as a device positioning technology to address the increasing demand for high accuracy indoor location services. Bluetooth LE now includes features that enable one device to determine the presence, distance, and direction of another device.

Bluetooth LE Primer
Are you new to Bluetooth Low Energy (LE)? The Bluetooth® LE Primer explains key aspects of Bluetooth LE technology at a technical level. It also provides references to other study guides, papers, and formal specifications, making it as easy as possible to navigate the other Bluetooth SIG related resources.
The Bluetooth Low Energy (LE) Primer explains every layer of the Bluetooth LE stack, starting with the physical layer at the bottom and ending with the generic access profile at the top. Topics related to the layered architecture of the stack, such as security, are covered too. This is the place to start if you’re new to Bluetooth LE and want to learn about the technology from a technical perspective.
