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: This application discloses a Bluetooth reconnection method, and relates to the field of short-range wireless communications technologies. The method includes: When a charging case is closed, a first earbud breaks a Bluetooth connection, where the first earbud stores a Bluetooth address of a terminal and a Bluetooth address of a second earbud. When the charging case is opened, the charging case accommodates only the first earbud, and a first preset condition is met, the first earbud sends a first paging request to the second earbud based on the Bluetooth address of the second earbud. The first preset condition is that the Bluetooth connection includes a Bluetooth connection between the first earbud and the second earbud. In this way, reconnection duration of the first earbud when the charging case is opened can be reduced.

Abstract: This application discloses a TWS headset connection method, including: A TWS headset includes a first earbud and a second earbud; the first earbud performs scanning at a first scanning duty cycle, where the first scanning duty cycle is 100%; the second earbud performs advertising; if the first earbud does not find the advertising through scanning, the first earbud determines or judges whether scanning duration of the first earbud exceeds an advertising period of the second earbud; and if the scanning duration of the first earbud exceeds the advertising period of the second earbud, the first earbud is connected to an electronic device that has performed a Bluetooth pairing with the first earbud last time; or if the scanning duration of the first earbud does not exceed the advertising period of the second earbud, the first earbud continues scanning.

Abstract: This application relates to the field of short-range wireless communication technologies, and discloses a Bluetooth pairing method. The method includes: when a terminal receives a first operation of a user, the terminal sends an inquiry request to a Bluetooth device, where the inquiry request is used to obtain a Bluetooth address of the Bluetooth device. When receiving the inquiry request, the Bluetooth device sends an inquiry response to the terminal, where the inquiry response includes the Bluetooth address of the Bluetooth device. The Bluetooth device sends an extended inquiry response to the terminal, where the extended inquiry response includes a device name of the Bluetooth device. After receiving the extended inquiry response, the terminal displays the device name of the Bluetooth device. In this way, the terminal can reduce a time consumed by the terminal in a process from discovering the Bluetooth device to pairing with the Bluetooth device.

Abstract: A Bluetooth communication method is disclosed, and relates to the field of short-range wireless communications technologies. The method includes: A terminal receives a play operation performed by a user on first audio data. The terminal sends first indication information to a Bluetooth device when a service type of the first audio data is a first service type, where the first indication information is used by the Bluetooth device to set a buffer time length for the audio data to first duration. The Bluetooth device receives the first audio data sent by the terminal via Bluetooth, and buffers the first audio data. The Bluetooth device starts to play the buffered first audio data when the buffer time length for the first audio data reaches the first duration. In this way, the terminal can perform targeted delay control on audio data playback of the Bluetooth device in different application scenarios.

Abstract: This application discloses a Bluetooth connection method, and relates to the field of short-range wireless communications technologies. The method includes: A terminal sends a service inquiry request to a Bluetooth device after the terminal and the Bluetooth device establish an asynchronous connectionless ACL link. The service inquiry request includes information about a service supported by the terminal. The Bluetooth device sends a service inquiry response to the terminal in response to the service inquiry request. The service inquiry response includes information about a service supported by the Bluetooth device. The terminal performs pairing with the Bluetooth device after the terminal receives the service inquiry response sent by the Bluetooth device. The terminal establishes a connection based on a first service to the Bluetooth device when both the terminal and the Bluetooth device support the first service. This reduces a period of time for establishing a Bluetooth service connection.
