    Abstract: An audio control system includes a BLUETOOTH headset, a first electronic device, and a second electronic device. The first electronic device sends a first media audio stream to the BLUETOOTH headset in response to a first operation of a user. The BLUETOOTH headset receives the first media audio stream from the first electronic device, and outputs the first media audio stream. The second electronic device outputs, in response to a second operation of the user, a second media audio stream through a first preset channel other than the BLUETOOTH headset. When the BLUETOOTH headset receives the first operation of the user, it performs one of the following actions: interrupting the second BLUETOOTH connection between the BLUETOOTH headset and the second electronic device or sending a first message to the second electronic device indicating that the BLUETOOTH headset is occupied.

    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 power control device and method, the method including obtaining, by a terminal device, class of device information of a peer device, determining, by the terminal device, based on the class of device information, a class of device of the peer device, and performing at least one of sending, by the terminal device, in response to the terminal device determining that the class of device of the peer device is a non-preset class of device, data to the peer device at a first transmit power, or sending, by the terminal device, data to the peer device at a second transmit power—in response to the terminal device determining that the class of device of the peer device is a preset class of device, —where the terminal device establishes a Bluetooth connection to the peer device, and the first transmit power is less than the second transmit power.

    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.
