Abstract: Embodiments of the present invention provide a communication establishment method. The method includes: receiving, by a first terminal, a first broadcast message of a first wireless communications mode sent by a second terminal, where the first broadcast message carries a second wireless communications mode supported by the second terminal and a status and/or supported protocol information of the second wireless communications mode; and determining, by the first terminal based on the second wireless communications mode supported by the second terminal and the status and/or the supported protocol information of the second wireless communications mode, whether to connect to the second terminal. According to the foregoing method provided in the embodiments of the present invention, in a first wireless communication phase, a status and/or a supported protocol of a second wireless communications mode can be obtained, so that the second wireless communications mode is learned of in advance and terminals are filtered, thereby improving efficiency of selecting a wireless communications mode and establishing a communication connection.

Abstract: Embodiments of the present invention provide a Bluetooth connection method, including: sending, by a first terminal, a Bluetooth low energy BLE advertising message, where the BLE advertising message includes device information; receiving, by a second terminal, the BLE advertising message; obtaining, by the second terminal, the device information; matching, by the second terminal, the device information with prestored device information; if the device information successfully matches the prestored device information, initiating, by the second terminal, a classic Bluetooth connection request to the first terminal; and establishing, by the first terminal, a classic Bluetooth connection to the second terminal. Power consumption of BLE is low.
