Among them: high-speed Bluetooth mainly focuses on data exchange and transmission; traditional Bluetooth focuses on information communication and device connection; Bluetooth low energy, as its name implies, is mainly connected to devices that do not require much bandwidth. The predecessor was actually Wibree technology developed by NOKIA. This is a very low power mobile wireless communication technology developed for mobile devices. After being accepted and standardized by SIG, it was renamed Bluetooth Low Energy ). These three protocol specifications can also be combined with each other to achieve a wider range of application modes. In addition, Bluetooth 4.0 also increases the transmission distance of Bluetooth to more than 100 meters (in low power mode).
