Bluetooth Dual Mode means that it supports the Basic Rate (BR) and Enhanced Data Rate (EDR) work of legacy Bluetooth, as well as the latest Low Power (LE) standard.
Bluetooth?4.0 is the beginning of the dual-mode standard, adding a low-power Bluetooth technology (LE) in addition to the included legacy Bluetooth technical standards for different application scenarios.
Traditional Bluetooth is also known as classic Bluetooth, as early as the previous version 1.0 began to +EDR? and other bases on the development of the perfect, and low-power Bluetooth is Nokia's Wibree standard on the formation of another technology standard. So dual-mode Bluetooth devices support both low-power Bluetooth and BR/EDR Bluetooth.
Extended information:
Traditional Bluetooth is used to solve the role of the actual data transmission, for example, Bluetooth headset can be used for audio transmission, Zifan also shared before the handheld gimbal device can be used to control the device as well as to realize the transmission of the video image and so on.
Together with the EDR enhanced data rate for streaming media and other applications is a great enhancement, while the low-power Bluetooth is used for data transmission for real-time requirements of higher, but the data rate is relatively low products, more for smart wearable devices, as well as our common Bluetooth mouse and Bluetooth keyboard, of course, there may be other devices, etc., and the application of the industry and the direction of the relatively broader. The application of the industry and direction is also relatively broad.
