Device pairing

1. A method for establishing a wireless communication connection for exchanging of control messages between a first device and a second device using both of a locking mechanism and a pairing protocol, the method comprising:

applying the non-standardized locking mechanism to set between the first device and second device whether access to the first pairing protocol is locked or unlocked; and

on condition of being activated by said locking mechanism, performing a pairing between the first device and the second device using the first pairing protocol,

upon completion of the pairing protocol activating the wireless communication connection for exchanging of control messages; and further switching the second device from a state in which the second device reports that it does not have a display to a mode in which the second device reports that it does have a display, thereby triggering a switching of mode wherein the second device switches from a mode which requires the first device to use the first pairing protocol to a mode which requires the first device to use a second pairing protocol.

2. The method of claim 1 , wherein responsive to activation by the locking mechanism, the first device obtains authentication for the pairing, and the completion of the pairing is conditional on said authentication.

3. The method of claim 1 , wherein the locking mechanism is performed between a third device having already paired with the second device, and the second device, and said pairing protocol is activated between the first device and the second device on condition of the locking mechanism being performed by the third device.

4. The method of claim 1 , wherein the locking mechanism requires an unobstructed line of sight between the first device and second device.

5. The method of claim 1 , wherein the locking mechanism requires the first and second devices to be within a pre-determined physical proximity.

6. The method of claim 1 , wherein the second pairing protocol requires a user to manually enter a code of the second device into a user interface of the first device, whereas the first pairing protocol does not.

7. The method of claim 1 , wherein said locking mechanism comprises a timer mechanism configured to trigger said switching of mode in response to the elapsing of a pre-determined window of time.

8. The method of claim 1 , wherein the first pairing protocol is Bluetooth JustWorks pairing.

9. The method of claim 1 , wherein the second pairing protocol is Bluetooth PassKey pairing.

10. The method of claim 1 , wherein the locking mechanism is determining if a new user account belongs to a known user by comparing account registration information.

11. The method of claim 10 , wherein the locking mechanism is completed using a shared secret between the first device and a server, and the second device and said server.

12. A device to be controlled, being operable to establish a wireless communication connection with another, controlling device for exchanging of control messages using both of a locking mechanism and a pairing protocol, the controlled device comprising:

a control logic for applying the locking mechanism to set whether access to the pairing protocol is locked or unlocked; and

a transmitter and receiver configured to: perform a pairing between the controlled device and the controlling device using the first pairing protocol, on condition of being activated by said locking mechanism, wherein upon completion of the pairing protocol activating the wireless communication connection for receiving of control messages; and further switching the controlled device from a state in which the controlled device reports that it does not have a display to a mode in which the controlled device reports that it does have a display, thereby triggering a switching of mode wherein the controlled device switches from a mode which requires the controlling device to use a first pairing protocol to a mode which requires the controlling device to use a second pairing protocol.

13. A non-transitory computer program product comprising code embodied on computer-readable storage and configured so as when run on one or more processing units of a controlled device to establish a wireless communication connection with another, controlling device for exchanging of control messages using both of a locking mechanism and a pairing protocol, the computer program product being configured to perform operations of:

applying the locking mechanism to set whether access to the pairing protocol is locked or unlocked; and

performing a pairing between the controlled device and the controlling device using the first pairing protocol, on condition of being activated by said locking mechanism, wherein upon completion of the standardized pairing protocol activating the wireless communication connection for receiving of control messages; and further switching the controlled device from a state in which the controlled device reports that it does not have a display to a mode in which the controlled device reports that it does have a display, thereby triggering a switching of mode wherein the controlled device switches from a mode which requires the controlling device to use a first pairing protocol to a mode which requires the controlling device to use a second pairing protocol.
