Abstract

The present disclosure relates to a method and an electronic device for processing data on the basis of a Bluetooth Low Energy (BLE) protocol. The electronic device includes a Bluetooth control module and a processor. The Bluetooth control module stores a modified BLE protocol stack including at least two Attribute Protocols (ATTs) for use with an application, the modified BLE protocol stack includes a first path and a second path. The first path includes a first ATT protocol to process an ATT command of the application, and the second path includes a second ATT protocol to process an ATT command of the application. The processor is coupled to the Bluetooth control module. The processor processes data of the application including the ATT command, using the modified BLE protocol stack including the at least two ATTs of the Bluetooth control module.

Claims

1. An electronic device comprising:

a Bluetooth control module that stores a modified Bluetooth Low Energy (BLE) protocol stack including at least two Attribute (ATT) Protocols for use with an application, the modified BLE protocol stack including a first path and a second path, the first path including a Generic Attribute profile (GATT) and a first ATT protocol to process a first ATT command of the application, the second path including an audio layer and a second ATT protocol to process a second ATT command of the application; and

a processor coupled to the Bluetooth control module,

wherein the processor processes data of the application including the first ATT command and the second ATT command, using the modified BLE protocol stack including the at least two ATTs of the Bluetooth control module, and

wherein the first ATT protocol of the first ATT command and the second ATT protocol of the second ATT command are processed, by the electronic device, at a same time.

2. The electronic device of claim 1, wherein the first path further comprises an application layer, a Logical Link Control and Adaptation Protocol (L2CAP), and a link layer.

3. The electronic device of claim 1, wherein the second path further comprises an L2CAP, and a link layer.

4. The electronic device of claim 1, wherein the second ATT command, which is transferred through the second path of the application, is an audio-related command.

5. The electronic device of claim 1, wherein the first ATT protocol uses a fixed channel identifier and the second ATT protocol uses a channel identifier allocated to a reserved area or a dynamic allocation area.

6. The electronic device of claim 1, wherein the modified BLE protocol stack further comprises a third path including a Digital Signal Processing (DSP), an L2CAP, and a link layer.

7. The electronic device of claim 1, wherein the application is a hearing aid-related application.

8. An electronic device comprising:

a memory;

at least one processor; and

at least one module stored in the memory and configured to be executable by the at least one processor,

wherein the module;

during booting, loads a modified Bluetooth Low Energy (BLE) protocol stack, which includes a first path having a Generic Attribute profile (GATT) and a first Attribute (ATT) protocol, and a second path having an audio layer and a second ATT protocol, for use with an application stored in a first memory, in a second memory;

performs a Bluetooth connection to a second electronic device through a physical layer and a link layer in the modified BLE protocol stack;

determines whether an event is generated in a higher layer of the link layer in the BLE protocol stack; and

according to a type of the event, comprises a command for transferring a command of the application to the second electronic device,

wherein the first ATT protocol of a first ATT command and the second ATT protocol of a second ATT command are processed by the electronic device, at a same time.

9. The electronic device of claim 8, wherein the command for transferring a command of the application to the second electronic device transfers an ATT command of the application to the second electronic device through the first path including the GATT and the first ATT protocol in the modified BLE protocol stack when the event relates to the first ATT command in the first path, and transfers the ATT command of the application to the second electronic device through the second path including an audio layer and the second ATT protocol in the modified BLE protocol stack when the event relates to the second ATT command in the second path.

10. The electronic device of claim 9, wherein the first path further comprises an application layer, a Logical Link Control and Adaptation Protocol (L2CAP), and a link layer.

11. The electronic device of claim 9, wherein the second path further comprises an L2CAP and a link layer.

12. The electronic device of claim 9, wherein the second ATT command, which is transferred through the second path of the application, is an audio-related command.

13. The electronic device of claim 9, wherein the first ATT protocol uses a fixed channel identifier and the second ATT protocol uses a channel identifier allocated to a reserved area or a dynamic allocation area.

14. The electronic device of claim 9, wherein the modified BLE protocol stack further comprises a third path including a Digital Signal Processing (DSP), an L2CAP, and a link layer.

15. A method of a first electronic device, the method comprising:

during booting, loading a modified Bluetooth Low Energy (BLE) protocol stack, which includes a first path having a Generic Attribute profile (GATT) and a first Attribute (ATT) protocol, and a second path having an audio layer and a second ATT protocol, for use with an application stored in a first memory, in a second memory;

performing a Bluetooth connection to a second electronic device through a physical layer and a link layer in the modified BLE protocol stack;

determining whether an event is generated in a higher layer of the link layer in the BLE protocol stack; and

according to a type of the event, transferring a command of the application to the second electronic device,

wherein the first ATT protocol of a first ATT command and the second ATT protocol of a second ATT command are processed, by the first electronic device, at a same time.

16. The method of claim 15, wherein transferring the command of the application to the second electronic device comprises:

transferring an ATT command of the application to the second electronic device through the first path including the GATT and the first ATT protocol in the modified BLE protocol stack when the event relates to the first ATT command in the first path, and

transferring the ATT command of the application to the second electronic device through the second path including an audio layer and the second ATT protocol in the modified BLE protocol stack when the event relates to the second ATT command in the second path.

17. The method of claim 16, wherein the first path further comprises an application layer, a Logical Link Control and Adaptation Protocol (L2CAP), and a link layer.

18. The method of claim 16, wherein the second path further comprises an L2CAP and a link layer.

19. The method of claim 16, wherein the second ATT command, which is transferred through the second path of the application, is an audio-related command.

20. The method of claim 16, wherein the first ATT uses a fixed channel identifier and the second ATT protocol uses a channel identifier allocated to a reserved area or a dynamic allocation area.
