Abstract: A point-to-multipoint data transmission method includes separately transmitting, by an electronic device, audio data to a first earbud and a second earbud through two connected isochronous streams (CISs) of a same connected isochronous group (CIG), where the two CISs share a CIG presentation point of the CIG, where the CIG presentation point is a time point at which the first earbud and the second earbud play the audio data, transmitting, by the electronic device, the audio data to the first earbud through the first CIS from an anchor point of the first CIS, and transmitting, by the electronic device, the audio data to the second earbud through the second CIS from an anchor point of the second CIS.

Abstract: A BLUETOOTH connection method includes an electronic device establishing basic rate (BR)/enhanced data rate (EDR) connection to an accessory device. The electronic device determines that the electronic device supports a dual-mode connection and that the accessory device also supports the dual-mode connection. The dual-mode connection includes the BR/EDR connection and a BLUETOOTH Low Energy (BLE) connection. The electronic device disconnects the BR/EDR connection to the accessory device, and establishes the BLE connection to the accessory 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: A point-to-multipoint data transmission method and device, the method including a left earbud and a right earbud of a true wireless stereo (TWS) headset separately performing pairing and service content negotiation with an electronic device. The left earbud receives left configuration information sent by the electronic device, to configure a left ISO channel, and the right earbud receives right configuration information sent by the electronic device, to configure a right ISO channel. The left earbud receives, based on the BLE-based audio profile, audio data that is sent by the electronic device through the left ISO channel, and the right earbud receives, based on the BLE-based audio profile, the audio data that is sent by the electronic device through the right ISO channel. The left earbud and the right earbud play the respectively received audio data based on a first timestamp.

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 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.
