METHOD FOR ESTABLISHING SERVICE CONNECTION, BLUETOOTH MASTER DEVICE, CHIP, AND BLUETOOTH SYSTEM

This application provides a service connection establishment method, a Bluetooth master device, a chip, and a Bluetooth system. After scanning a device combination including at least two Bluetooth slave devices, the Bluetooth master device, if required to establish a service connection with each of Bluetooth slave devices in the device combination, needs to do as follows: in a pairing phase, the Bluetooth master device automatically pairs with another Bluetooth slave device in the device combination after completing pairing with one Bluetooth slave device in the device combination; in a service connection establishment phase, similarly, the Bluetooth master device automatically establishes a service connection with another Bluetooth slave device in the device combination after establishing a service connection with one Bluetooth slave device in the device combination. In this process, the scanned Bluetooth slave devices do not need to be manually selected one by one, and the Bluetooth master device automatically pairs with each Bluetooth slave device and establishes the service connection. This is a simple process, and a speed of service connection establishment is high.
