With years of intensive cultivation in the IoT industry, RF-star has been committed to providing wireless RF modules and solutions. As one of the world's most deployed wireless IoT connectivity technologies, Bluetooth has always been our strategic focus as it is enabled widely in IoT devices across all sectors and applications. According to the latest forecasts from ABI Research, 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 has Bluetooth technology been available to meet the growing demand for wireless communication across countless use cases for more than 20 years? The hard work and collaboration between Bluetooth Special Interest Group (SIG) member companies ahve driven the continuous innovation of the technology.

On 13 July 2021, the Bluetooth SIG released Bluetooth® Core Specification version 5.3. This new standard has several features that provide IoT device makers and application developers with significant reliability, energy efficiency and user experience improvements. All lead to a continuous 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
• Removal of the Alternate MAC and PHY (AMP) Extension

Congratulations to Bluetooth SIG on the release of the Bluetooth 5.3 specification. We believe that the new specification will enable Bluetooth technology to create ever more innovative ways to win the IoT race.

RF-star technology will persistently update the latest advancements in SIG's technology, conducting research and developing cutting-edge industry technologies. This will enable our customers to maintain their competitive edge in the rapidly evolving wireless field. We eagerly anticipate the unveiling of new products that harness the exciting capabilities of Bluetooth 5.3 through our collaborative efforts.
