Abstract: An audio data transmission method. An electronic device transmits audio data to a first earbud of a TWS headset by using a first CIS of a first CIG, and transmits audio data to a second earbud of the TWS headset by using a second CIS of the first CIG. The electronic device determines that the TWS headset is switched from a double-earbud mode (namely, a mode in which the first earbud and the second earbud are used together as audio input/output devices of the electronic device) to a first single-earbud mode (namely, a mode in which the first earbud is independently used as an audio input/output device of the electronic device). In response to the determining, the electronic device deactivates the second CIS, stops transmitting audio data to the second earbud by using the second CIS, and continues transmitting audio data to the first earbud by using the first CIS.

Abstract: A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.

Abstract: A Bluetooth connection method and a related apparatus are disclosed, and relate to the field of short-range wireless communications technologies. A first electronic device establishes a BLE connection to a second electronic device, and exchanges data with the second electronic device based on a first connection interval. The first electronic device further establishes a BR/EDR connection to a third electronic device. When device class information of the second electronic device is the same as device class information prestored in a memory, the first electronic device exchanges data with the second electronic device based on a second connection interval. The second connection interval is greater than the first connection interval. In this way, a throughput speed of exchanging data by the third electronic device can be increased.
