Abstract

The present application is applicable to the field of smart terminal technologies, and a Bluetooth connection method and device and a smart terminal are provided. The method includes: searching, by a terminal device, for a dual-mode Bluetooth device and establishing a connection relationship in a first Bluetooth mode with the dual-mode Bluetooth device; obtaining identification information of the dual-mode Bluetooth device; and establishing a connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information.

First claim

What is claimed is:

1. A Bluetooth connection method, comprising:
searching, by a terminal device, for a dual-mode Bluetooth device, and establishing a connection relationship in a first Bluetooth mode with the dual-mode Bluetooth device;
obtaining, by the terminal device, a broadcast packet sent from the dual-mode Bluetooth device in a Bluetooth Low Energy mode;
obtaining, by the terminal device, identification information of the dual-mode Bluetooth device according to the broadcast packet sent from dual-mode Bluetooth device; and
automatically establishing, by the terminal device, a stable connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information of the dual-mode Bluetooth device when the dual-mode Bluetooth device is switched into the second Bluetooth mode, wherein the first Bluetooth mode is one of a classic Bluetooth mode and a Bluetooth Low Energy mode of the dual-mode Bluetooth device, and the second Bluetooth mode is the other one of the classic Bluetooth mode and the Bluetooth Low Energy mode of the dual-mode Bluetooth device,
wherein the terminal device comprises:
a first connection module, configured to make the terminal device search for a dual-mode Bluetooth device and establish a connection relationship in a first Bluetooth mode with the dual-mode Bluetooth device;
an obtaining module, configured to obtain identification information of the dual-mode Bluetooth device; and
a second connection module, configured to establish a connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information,

wherein, when the first Bluetooth mode is the classic Bluetooth mode, the second connection module comprises:
a comparison unit, configured to obtain, according to the connected classic Bluetooth mode, the identification information of the dual-mode Bluetooth device and to determine whether the identification information of the dual-mode Bluetooth device is consistent with identification information obtained according to the broadcast packet by comparison; and
a connection establishing unit configured to establish a connection relationship in the Bluetooth Low Energy mode with the dual-mode Bluetooth device when the identification information of the dual-mode Bluetooth device is consistent with identification information obtained according to the broadcast packet,

wherein, when the first Bluetooth mode is the Bluetooth Low Energy mode, the second connection module comprises:
a calling unit, configured to call identifier information acquired according to the broadcast package; and
a query unit, configured to search for a smart terminal having the same identification information as the identification information acquired according to the broadcast packet among smart terminals with the classic Bluetooth mode enabled, where the smart terminal is the dual-mode Bluetooth device, so as to establish the connection relationship in the classic Bluetooth mode with the dual-mode Bluetooth device, and

wherein the dual-mode Bluetooth device comprises:
a Bluetooth mode enabling module, configured to enable the dual-mode Bluetooth device to establish the connection relationship in the first Bluetooth mode with the terminal device after a Bluetooth mode is enabled;
a sending module, configured to send the identification information of the dual-mode Bluetooth device to the terminal device; and
an instructing module, configured to instructing the terminal device to establish the connection relationship in the second Bluetooth mode with the dual-mode Bluetooth device according to the identified information.

2. The Bluetooth connection method according to claim 1 , wherein when the first Bluetooth mode is the classic Bluetooth mode, the step of establishing a connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information comprises:
searching for, among dual-mode Bluetooth devices with the Bluetooth Low Energy mode enabled, a dual-mode Bluetooth device having a same identification information as identification information obtained according to the broadcast packet as the dual-mode Bluetooth device; and
establishing a connection relationship in the Bluetooth Low Energy mode with the dual-mode Bluetooth device.

3. The Bluetooth connection method according to claim 1 , wherein when the first Bluetooth mode is the Bluetooth Low Energy mode, the step of establishing a connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information comprising:
searching for, among dual-mode Bluetooth devices with the classic Bluetooth mode enabled, a dual-mode Bluetooth device having a same identification information as identification information obtained according to the broadcast packet as the dual-mode Bluetooth device; and
establishing a connection relationship in the classic Bluetooth mode with the dual-mode Bluetooth device.

4. The Bluetooth connection method according to claim 1 , wherein the identification information comprises:
a name of the dual-mode Bluetooth device or/and a classic Bluetooth address of the dual-mode Bluetooth device in the classic Bluetooth mode.

5. The Bluetooth connection method according to claim 1 , wherein the dual-mode Bluetooth device supports a first application of the Bluetooth Low Energy mode, and the step of obtaining identification information of the dual-mode Bluetooth device, and establishing a connection relationship in a second Bluetooth mode with the dual-mode Bluetooth device according to the identification information comprises:
searching, by an APP for first application of Bluetooth Low Energy mode of the smart terminal, and according to at least one received Bluetooth broadcast packet, for a dual-mode Bluetooth device that has the second Bluetooth mode enabled and supports the first application of the Bluetooth Low Energy mode;
matching identification information of the searched dual-mode Bluetooth device with the identification information of the dual-mode Bluetooth device that has established the connection relationship in the first Bluetooth mode with the smart terminal; and
establishing a connection relationship in the second Bluetooth mode with the matched dual-mode Bluetooth device.

6. The Bluetooth connection method according to claim 1 , the obtaining module comprises:
a broadcast packet sending unit, configured to obtain a broadcast packet sent from the dual-mode Bluetooth device in the Bluetooth Low Energy mode; and
an identification information obtaining unit, configured to obtain the identification information of the dual-mode Bluetooth device according to the broadcast packet.

7. A Bluetooth connection method, comprising:
establishing, by a dual-mode Bluetooth device, a connection relationship in a first Bluetooth mode with a terminal device, after a Bluetooth mode is enabled;
sending, by the dual-mode Bluetooth device in the Bluetooth Low Energy mode, a broadcast packet, the broadcast packet carrying identification information of the dual-mode Bluetooth device and the information indicating that the dual-mode Bluetooth device supports a first application of the Bluetooth Low Energy mode; and
instructing the terminal device to automatically establish a stable connection relationship in the second Bluetooth mode with the dual-mode Bluetooth device according to the identification information of the dual-mode Bluetooth device when the dual-mode Bluetooth device is switched into the second Bluetooth mode, wherein the first Bluetooth mode is one of a classic Bluetooth mode and a Bluetooth Low Energy mode of the dual-mode Bluetooth device, and the second Bluetooth
