Abstract

The inventor provides a Bluetooth automatic connection method and a master device, slave device, and system for implementing Bluetooth automatic connection, solving the problem that manual selection and connection are needed in a scenario in which there are multiple Bluetooth devices. The present invention relates to implementation of connection between Bluetooth devices, and in particular, quick automatic connection of the Bluetooth devices. The method includes the following steps: enabling, by a first device, a Bluetooth function, to obtain Bluetooth device names in a communication range; determining, one by one, whether the Bluetooth device names in the communication range contain a specific character, and if any Bluetooth device name contains the specific character, determining a Bluetooth device corresponding to the Bluetooth device name as a candidate Bluetooth device; connecting, by the first device, to a first server, where the first server stores validly registered Bluetooth device information; and according to the validly registered Bluetooth device information and names of candidate Bluetooth devices, determining whether there is a validly registered Bluetooth device in the candidate Bluetooth devices.
