Abstract

Described are a method and a Bluetooth device that upon powering up (202), the device automatically enters (306) discoverable mode without user intervention when its paired device list is empty (304). Also described is emptying (206) the paired device list. Further described is a method and Bluetooth device having one or more devices listed in its paired device list and wherein attempts are made at communication with the listed devices in one or more predetermined manners and if the attempts are not successful, automatically entering discoverable mode (306). Still further described is a method and device for attempting communication with the previously paired devices which may be interposed with entering into discoverable mode until either one is successful.

Claims

1. A method in a Bluetooth device having a memory configured to store a paired device list, the method comprising:

powering up the Bluetooth device;

determining whether there is a device listed in a paired device list; and

entering automatically discoverable mode if there is no device listed in a paired device list.

2. The method of claim 1, further comprising:

adding a device to the paired device list; and

emptying the paired device list.

3. The method of claim 2, further comprising:

providing a user manual command to empty the paired device list.

4. The method of claim 2, further comprising:

providing a speech command to empty the paired device list.

5. The method of claim 2, further comprising:

providing an electronic input to the Bluetooth device to empty the paired device list.

6. A method in a Bluetooth device having a memory configured to store a paired device list, the method comprising:

powering up the Bluetooth device;

determining whether there is a device listed in a paired device list;

attempting communication with at least one device listed in the paired device list if the paired device list is nonempty; and

entering discoverable mode if attempting communication with the at least one device is unsuccessful.

7. The method of claim 6, further comprising:

retrieving the most recently paired device from the paired device list to attempt communication therewith.

8. The method of claim 6, further comprising:

retrieving a plurality of the most recently paired device from the paired device list to attempt communication therewith.

9. The method of claim 6, further comprising:

emptying the paired device list.

10. The method of claim 6, wherein the paired device list comprises a plurality of devices, the method further comprising:

interposing periods during which the Bluetooth device is in discoverable mode between periods of attempting communication with the plurality of devices until a criterion is met.

11. The method of claim 10, wherein attempting communication continues for a predetermined period of time.

12. The method of claim 10, wherein attempting communication continues for a random period of time.

13. The method of claim 10, wherein the Bluetooth device remains in discoverable mode for a predetermined period of time.

14. The method of claim 10, wherein the Bluetooth device remains in discoverable mode for a random length of time.

15. The method of claim 10, wherein the criterion comprises that attempting communication with at least one device is successful.

16. The method of claim 10, wherein the criterion comprises that attempting communication with the plurality of devices is unsuccessful.

17. A Bluetooth device, comprising:

a memory unit configured to store instructions;

a processor configured to execute instructions stored in the memory unit; and

a discoverable mode module with instructions configured to place the Bluetooth device in discoverable mode without user action when a criterion is met.

18. The Bluetooth device of claim 17, wherein the memory unit is further configured to store a paired device list, and wherein the criterion comprises that no devices are listed in a paired device list.

19. The Bluetooth device of claim 17, wherein the memory unit is further configured to store a paired device list, and wherein the criterion comprises that attempting communication with at least one device on the paired device list has failed.

20. The Bluetooth device of claim 17, wherein the Bluetooth device is a headset.
