Abstract

A method for establishing a communication link between two devices, the communication link employing a protocol that provides for link establishment information sufficient for establishing a link between two devices to be negotiated between those devices; the method comprising: establishing communication links between each of the two devices and one or more further devices; transmitting from the one or more further devices to each of the two devices information that defines link establishment parameters for a link between the two devices; and establishing the link between the two devices using the defined link establishment parameters.

Claims

1. A method for establishing a communication link between a first device and a second device, the method performed by a third device and comprising:

establishing a first direct link between the first device and the third device;

establishing a second direct link between the second device and the third device;

determining that the first device and the second device are configured for use by a single user based on notifications received, by the third device, from the first device and the second device within a time period;

generating one or more link establishment parameters for a third direct link between the first device and the second device, wherein the one or more link establishment parameters include a device address of at least one of the first device or the second device to be used for authentication of the third direct link, encryption of communications over the third direct link, and addressing communications over the third direct link;

transmitting the one or more link establishment parameters from the third device to the first device and to the second device via the first direct link and the second direct link, respectively; and

establishing the third direct link between the first and second devices using the one or more link establishment parameters.

2. The method of claim 1, wherein the link establishment parameters include a link key for authentication of the third direct link or (ii) encryption of communications over the third direct link.

3. The method of claim 1, wherein the first, second, and third direct links are established according to a Bluetooth protocol.

4. The method of claim 1, wherein the first device and the second device are user input devices.

5. The method of claim 4, wherein the first device and the second device have different user interfaces.

6. The method of claim 4, wherein the first device and the second device are game controllers.

7. The method of claim 4, wherein the third device comprises a computing device.

8. The method of claim 7, wherein the computing device is a game console.

9. The method of claim 7, wherein the first device is configured to sense first user input and to transmit the first user input to the second device via the third direct link.

10. The method of claim 1, wherein the link establishment parameters include an operational state indicator to indicate that at least one of the first device and the second device should adopt an indicated operational state.

11. The method of claim 10, wherein the operational state is a state in which the first device or the second device awaits initiation of a link from another device.

12. The method of claim 10, wherein the operational state is a state in which the first device initiates a link to the second device.

19. The method of claim 1, wherein the determining that the first device and the second device are configured for use by a single user comprises determining that the first device and the second device each receive button pushes within the time period.

13. A wireless device, comprising:

one or more processors; and

a memory storing one or more programs comprising instructions that, when executed by the one or more processors, cause the wireless device to establish a communication link between a first device and a second device by performing operations comprising;

establishing a first direct link with the first device;

establishing a second direct link with the second device;

determining that the first device and the second device are configured for use by a single user based on notifications received, by the wireless device, from the first device and the second device within a time period;

generating one or more link establishment parameters for a third direct link between the first device and the second device, wherein the one or more link establishment parameters include a device address of at least one of the first device or the second device to be used for authentication of the third direct link, encryption of communications over the third direct link, and addressing communications over the third direct link;

transmitting the one or more link establishment parameters to the first device and to the second device via the first direct link and the second direct link, respectively; and

establishing the third direct link between the first and second devices using the one or more link establishment parameters.

14. The wireless device of claim 13, wherein execution of the instructions causes the wireless device to perform operations further comprising:

receiving user input, sensed by the first device, from the second device via the second direct link.

15. The wireless device of claim 13, wherein execution of the instructions causes the wireless device to perform operations further comprising:

transmitting data to the first device via the second device using the first and third direct links.

16. The wireless device of claim 13, wherein the first device is a wireless mouse, and the second device is a wireless keyboard.

17. The wireless device of claim 13, wherein the wireless device is a gaming console, the first device is a first game controller, and the second device is a second game controller.

18. The wireless device of claim 13, wherein execution of the instructions for determining that the first device and the second device are configured for use by a single user comprises:

determining that the first device and second device each receive button pushes within the time period.
