Bluetooth EDR is a version of Bluetooth technology, which is the abbreviation of "enhanced data rate", meaning "enhanced data rate". It is a wireless communication protocol that can transmit data between devices by radio waves. Compared with the traditional Bluetooth technology, it provides higher transmission rate and shorter delay time. It is widely used in mobile devices, car stereos and smart homes.

Bluetooth EDR has the characteristics of fast transmission speed, low power consumption, wide application and long distance. Among them, the most obvious feature is high-speed transmission. Bluetooth EDR can achieve higher data transmission rate on the basis of standard Bluetooth protocol. In addition, Bluetooth EDR has low power consumption when transmitting data, which is a very important feature because it can prolong the service life of the equipment.

Bluetooth EDR is widely used in mobile devices, car stereos and smart homes. In terms of mobile devices, mobile phones, tablet computers, Bluetooth headsets and other devices all use Bluetooth EDR to realize wireless communication. In car audio, Bluetooth EDR can realize high-quality wireless audio transmission, making in-car entertainment more convenient. In the field of smart home, Bluetooth EDR can control various devices in the home, such as lighting, temperature, faucet and so on. Make smart homes more comfortable and convenient.
