Abstract: This application provides a service connection establishment method, a Bluetooth master device, and a chip. 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. This is a simple process, and a speed of service connection establishment is high.
