What does Bluetooth 5.0 dual mode mean?

Bluetooth dual-mode means supporting the basic rate (BR) and enhanced data rate (EDR) of traditional Bluetooth, and also supporting the latest low power consumption (LE) standard.

Bluetooth? 4.0 is the beginning of the dual-mode standard. In addition to the traditional Bluetooth technology standard, low-power Bluetooth technology (LE) is added, which is suitable for different application scenarios.

Traditional Bluetooth, also known as Classic Bluetooth, started +EDR as early as the previous version of 1.0? And low-power Bluetooth is another technical standard formed on Nokia's Wibree standard. Therefore, dual-mode Bluetooth devices support both low-power Bluetooth and BR/EDR Bluetooth.

Extended data:

Traditional Bluetooth is used to solve the problem of actual data transmission. For example, the Bluetooth headset can be used for audio transmission, and the previously shared handheld pan-tilt device can be used to control the device to realize video image transmission.
