Abstract: A method includes receiving, by a first Bluetooth device, an identity resolving key (IRK) from a server, and generating a resolvable private address based on the IRK. The method further includes sending, by the first Bluetooth device, a broadcast message. The broadcast message includes the resolvable private address. The resolvable private address is successfully verified by a second Bluetooth device pre-configured with the IRK.

Abstract: The present invention provides a method for discovering a Bluetooth device. The method includes: receiving, by a second Bluetooth device, a first broadcast frame of a first Bluetooth device; determining, by the second Bluetooth device, whether the first broadcast frame includes first indication information; and if the first broadcast frame includes the first indication information, sending, by the second Bluetooth device, at least one second broadcast frame within a preset time period after receiving the first broadcast frame, where the second broadcast frame includes second indication information, and the second indication information is used to instruct a Bluetooth device receiving the second broadcast frame to exchange information with the second Bluetooth device.

Abstract: Embodiments of this application provide a Bluetooth connection method, a system, and an electronic device. In the method, when a communication connection between an electronic device and a vehicle head unit is disconnected, the electronic device starts to scan a Bluetooth advertising signal. When a user carrying the electronic device is close to the vehicle head unit, the electronic device may obtain, through scanning, a Bluetooth advertising signal sent by the vehicle head unit. When obtaining, through scanning, the Bluetooth advertising signal sent by the vehicle head unit, the electronic device may start a vehicle manufacturer application when the vehicle manufacturer application is cleared by a system. The electronic device may reconnect to the vehicle head unit through Bluetooth by using the vehicle manufacturer application and a Bluetooth chip. Embodiments of this application can improve convenience of unlocking in a scenario in which a vehicle is insensibly unlocked.

Abstract: Embodiments of the present invention provide a Bluetooth connection method, including: sending, by a first terminal, a Bluetooth low energy BLE advertising message, where the BLE advertising message includes device information; receiving, by a second terminal, the BLE advertising message; obtaining, by the second terminal, the device information; matching, by the second terminal, the device information with prestored device information; if the device information successfully matches the prestored device information, initiating, by the second terminal, a classic Bluetooth connection request to the first terminal; and establishing, by the first terminal, a classic Bluetooth connection to the second terminal. Power consumption of BLE is low.
