Abstract: This application discloses a Bluetooth connection method, and relates to the field of short-range wireless communications technologies. The method includes: A terminal sends a service inquiry request to a Bluetooth device after the terminal and the Bluetooth device establish an asynchronous connectionless ACL link. The service inquiry request includes information about a service supported by the terminal. The Bluetooth device sends a service inquiry response to the terminal in response to the service inquiry request. The service inquiry response includes information about a service supported by the Bluetooth device. The terminal performs pairing with the Bluetooth device after the terminal receives the service inquiry response sent by the Bluetooth device. The terminal establishes a connection based on a first service to the Bluetooth device when both the terminal and the Bluetooth device support the first service. This reduces a period of time for establishing a Bluetooth service connection.
