What is the difference between Bluetooth 5.2 and 5.3?
There are many mobile phones that claim to support Bluetooth 5.3. So what is the difference between Bluetooth 5.3 and 5.2?
In fact, they are essentially the subsequent updated versions of Bluetooth 5, and there is not much difference in most of the performance and functions.
Compared with Bluetooth 5.2, Bluetooth 5.3 further improves the communication efficiency of Bluetooth low energy and the wireless coexistence of Bluetooth devices by improving the periodic broadcast, connection update and channel classification in Bluetooth low energy consumption.
At the same time, the power consumption of Bluetooth is also reduced. Moreover, Bluetooth 5.3 version also introduces some new features that enhance the security of classic Bluetooth BR/EDR (basic rate and enhanced rate).
Simply, the Bluetooth 5.3 version has lower latency, stronger anti-interference, and improved battery life, but the transmission rate (42Mbit/s) and transmission distance (300 meters) have not changed.
The difference between Bluetooth 5.3 and 5.2:
Low speed connection
- Some data transmissions cannot be transmitted in Bluetooth 5.2 due to the low rate.
- Bluetooth 5.3 solves this problem, allowing low-power and low-rate signals to be used.
- This mainly occurs on some medical equipment such as blood glucose meters . The appearance of 5.3 has greatly optimized medical work.
Enhanced encryption control
- For some open signals, such as access control, commercial lighting and other equipment.
- Bluetooth 5.3 improves their encryption key length control options for improved security.
- At the same time, because the administrator control is simpler, it can also be faster when connecting.
Periodic broadcast enhancement
- Bluetooth 5.2 needs to periodically broadcast to connected devices.
- Bluetooth 5.3 will improve broadcast stability, so that you can do more things with broadcast time.
Overall, the new Bluetooth 5.3 has some new features, but not many added.
