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: In this application, a same input device may randomly switch a focus device between a plurality of terminal devices. Before and after the focus device is switched, the input device may simultaneously maintain communication connections to the plurality of terminal devices, and exchange, in a background, information with a non-focus device based on a communication connection between the input device and the non-focus device. Based on the solutions disclosed in this application, the input device can implement seamless focus migration between the plurality of terminal devices based on a convenient operation of a user without relying on a wireless local area network (WLAN).
