Abstract

A method and a device for Bluetooth connection control for multiple playing devices, and a music playing system are provided. The method includes the following. A broadcast message is sent after a playing device is turned on, where the broadcast message is configured to inquire whether a Bluetooth function is enabled in other playing devices within the same music playing system of the playing device. Whether a response returned by the other playing devices is detected according to the broadcast message is received, where the response is configured to indicate that a playing device that returned the response has enabled the Bluetooth function. The Bluetooth function of the playing device is disabled when the response is received by the playing device. The Bluetooth function of the playing device is enabled when no response is received by the playing device.

or

enabling the Bluetooth function of the first playing device based on a determination that the first playing device and the second playing device do not belong to the same playing group, whereby the first playing device can be found by the smart terminal during a Bluetooth pairing process.

4. The method of claim 3, wherein the method further comprises the following after the enabling the Bluetooth function of the first playing device based on the determination that the first playing device and the second playing device do not belong to the same playing group:

setting a name of a Bluetooth module of the first playing device to be a name of the playing group to which the first playing device belongs.

5. The method of claim 1, wherein sending the broadcast message after the playing device is turned on comprises:

sending the broadcast message continuously for a predetermined number of times at first preset time intervals.

6. The method of claim 1, further comprising:

sending Bluetooth status information to the other playing devices successively at second preset time intervals when the Bluetooth function of the playing device is enabled; and

enabling the Bluetooth function of the playing device when the Bluetooth function of the playing device is disabled and no Bluetooth status information from the other playing devices is received, wherein the Bluetooth status information is configured to indicate that the Bluetooth function of a playing device that sent the Bluetooth status information is operating normally.

7. The method of claim 1, further comprising:

designating one playing device among the other playing devices to enable the Bluetooth function when the playing device receives a disable-instruction and the Bluetooth function of the playing device is enabled.

8. A device for Bluetooth connection control for multiple playing devices, disposed in a first playing device and comprising:

one or more processors; and

a memory, configured to store one or more programs, wherein when executed by the one or more processors, the one or more programs are adapted to cause the one or more processors to;

send a broadcast message after the first playing device is turned on, the broadcast message being configured to inquire whether a Bluetooth function is enabled in other playing devices within a same music playing system of the playing device;

detect whether a response returned by a second playing device of the other playing devices according to the broadcast message is received, the response being configured to indicate that the second playing device has enabled the Bluetooth function;

disable the Bluetooth function of the first playing device when the response is received by the first playing device; and

enable the Bluetooth function of the first playing device when no response is received by the first playing device, whereby the first playing device can be found by a smart terminal during a Bluetooth pairing process.

9. The device of claim 8, wherein when executed, the one or more programs are adapted to further cause the one or more processors to:

return a response to a third playing device of the other playing devices that sent a broadcast message, when the first playing device receives the broadcast message sent by the third playing device and the Bluetooth function of the first playing device is enabled.

10. The device of claim 8, wherein the music playing system comprises a plurality of playing groups and each playing group comprises one or more playing devices, wherein the one or more programs to disable the Bluetooth function of the first playing device comprise programs to:

determine whether the first playing device and the second playing device belong to the same playing group; and

disable the Bluetooth function of the first playing device when the first playing device and the second playing device belong to the same playing group, or to enable the Bluetooth function of the first playing device when the first playing device and the second playing device do not belong to the same playing group, whereby the first playing device can be found by the smart terminal during a Bluetooth pairing process.

11. The device of claim 10, wherein when executed, the one or more programs are adapted to further cause the one or more processors to:
