Abstract: A data sending method, a data receiving method, a data transmit end, and a data receive end are provided. The data sending method includes: obtaining a transmission path used for data transmission, where the transmission path currently uses a first physical link group to transmit data; switching, based on a preconfigured link switching policy and transmission information of the transmission path, a physical link used by the transmission path from the first physical link group to a second physical link group; sending a first link switching notification message to a data receive end, where the first link switching notification message includes information indicating that the physical link used by the transmission path is switched from the first physical link group to the second physical link group; and continuing transmitting the data through a transmission path that uses the second physical link group.

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: A first device obtains an advertising parameter used by a second device to send an advertising data packet, where the advertising parameter includes an advertising window and an advertising interval. The first device determines, based on the advertising window and the advertising interval by using a preset scanning model, a target scan parameter used by the first device, where the target scan parameter is a scan parameter used by the first device when power consumption of the first device is a preset threshold and a scan-to-discover time period satisfies a preset condition. The target scan parameter includes a target scan window and a target scan interval. The first device performs scanning based on the target scan window and the target scan interval.

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: The present disclosure relates to methods and devices for discovering a Bluetooth device. One example method includes receiving, by a second Bluetooth device, a first broadcast frame from 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 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.
