Bluetooth standards are a set of protocols that enable wireless communication between devices over short distances. These standards ensure that devices like smartphones, headphones, and speakers can connect and exchange data seamlessly. The most common versions include Bluetooth 4.0, Bluetooth 5.0, and the latest, Bluetooth 5.2, each offering improvements in speed, range, and energy efficiency. The Bluetooth Special Interest Group (SIG) oversees the development and promotion of these standards. They provide guidelines for manufacturers to ensure compatibility and interoperability among devices. This allows users to enjoy a wide range of products that can easily connect and work together, enhancing the overall user experience.
