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.

Abstract: An air mouse mode implementation method and a related device are provided. The method includes: An electronic device establishes a communication connection to a stylus through Bluetooth (S301); sends notification information to the stylus through the communication connection when detecting a screen casting event of the electronic device, where the notification information is used to indicate whether the stylus is to enter an air mouse mode (S302); receives a determining instruction sent by the stylus through the communication connection (S303); and enters the air mouse mode based on the determining instruction, and modifies, from an arrow icon to a dot icon, an indication icon corresponding to the stylus (S304). According to this method, operation convenience can be improved.
