Apple launched a new 13-inch MacBook Air notebook with an M2 chip in July 2022, which initially only supported Bluetooth 5.0 technology. According to Apple’s official updated technical specifications, the notebook is now upgraded to support the faster and more reliable 5.3 standards.
Apple introduced the 15-inch MacBook Air at this year’s WWDC developer conference and has since updated its technical specifications page to show that the 13-inch model also supports Bluetooth 5.3.
All new Mac, iPhone, iPad Pro, Apple Watch and second-generation AirPods Pro models released by Apple since September 2022 support Bluetooth 5.3.
Bluetooth 5.3 has lower latency, better anti-interference, improved battery life, improved transmission efficiency, security, and stability, and the following improvements to Bluetooth 5.3:
- Low-speed connections: Some data transfers cannot be passed in Bluetooth 5.2 due to the low speed. Bluetooth 5.3 solves this problem, allowing low-power and low-speed signals to be used. ex: It mainly appears on some medical equipment such as blood glucose meters. The emergence of 5.3 greatly optimizes medical work.
- Enhanced encryption control: For some open signals, ex: access control, commercial lighting and other equipment.
- Bluetooth 5.3 has increased its encryption key length control options, improving security. At the same time, because the administrator control is simpler, it can be faster when connecting.
- Periodic broadcast enhancement: Bluetooth 5.2 needs to periodically broadcast to connected devices. And Bluetooth 5.3 will improve broadcast stability so you can do more with your broadcast time.
