What is a Bluetooth Low Energy module
The Bluetooth Low Energy Module (BLE module for short) is a wireless communication component designed based on Bluetooth 4.0 and above standards, and is specially optimized for low-power and short-range data transmission scenarios. It achieves much lower energy consumption than traditional Bluetooth (Classic Bluetooth) by simplifying the protocol stack, reducing transmission power and optimizing the connection mechanism, while maintaining sufficient communication stability and data transmission capacity.
