According to the latest forecasts from ABI Research, the Bluetooth device shipments are expected to approach 5 billion units annually by 2022 and surpass 6 billion units annually by 2025.



What makes Bluetooth the go-to wireless technology for IoT device makers and application developers? It is the ubiquitous support and global interoperability on digital devices of all kinds and types!


Why Bluetooth technology is available to meet the growing demand for wireless communication across countless use cases for more than 20 years? Because the hard work and collaboration between Bluetooth Special Interest Group (SIG) member companies has driven the continuous innovation of the technology.



On 13 July 2021, the Bluetooth SIG released Bluetooth® Core Specification version 5.3. This new release adds several feature enhancements which provide IoT device makers and application developers with significant reliability, energy efficiency and user experience improvements. All these just ensure a continued global growth of Bluetooth enabled products.



New Features of Bluetooth 5.3:


  • Periodic Advertising Enhancement
  • Encryption Key Size Control Enhancements
  • Connection Subrating
  • Channel Classification Enhancement
