Abstract

The present invention automatically selects the wireless mode of a device. The user of a Bluetooth device has the benefit of discoverable mode with the relative safety of connectable mode. The mode of the device is automatically switched from discoverable to connectable and back based on the activity of the device. For example, the mode may be switched to discoverable mode when the device is determined to be active and to connectable mode when the device is determined to be inactive. The device may be determined to be active based on many criteria, including, but not limited to: determining when a screen associated with the device is active; determining when the device is not key locked; and determining when the device is active further comprises determining when a lid associated with the device is open.

Claims

1. A method for smart mode switching on a wireless device, comprising:

when the device is powered on;

receiving a command from a user to select either a discoverable mode or a connectable mode relating to a wireless technology of a device;

wherein the discoverable mode allows the wireless device to be discovered by other Bluetooth wireless devices that are within range of the wireless device and wherein a partnership may be initiated with the wireless device once the wireless device is discovered and wherein the connectable mode allows only partnered Bluetooth devices to discover the wireless device;

determining when the received command indicates a selection of the discoverable mode; and

when the received command indicates the selection of the discoverable mode;

determining when the device is active and inactive;

wherein determining when the device is active and inactive does not include determining when the device is powered on and powered off;

determining when to switch the mode based upon the activity of the device; and

automatically switching the mode selected from the discoverable mode and a connectable mode based upon the activity of the device;

wherein the mode is automatically switched between the discoverable mode and the connectable mode while the device is powered on and when the device can process a user interaction; and

determining when the received command indicates a selection of the connectable mode; and

when the received command indicates a selection of the connectable mode;

maintaining the device in the connectable mode when the device is both active and inactive such that whenever the wireless device is powered on it remains in the connectable mode and does not switch from the connectable mode to the discoverable mode based on the activity of the device.

2. The method of claim 1, wherein determining when to switch the mode of the device further comprises determining when the device moves between being active and being inactive.

3. The method of claim 2, wherein the discoverable mode and the connectable mode relate to Bluetooth modes.

4. The method of claim 2, wherein automatically switching the mode selected from the discoverable mode and the connectable mode based upon the activity of the device further comprises switching the mode to the discoverable mode when the device is active.

5. The method of claim 2, wherein automatically switching the mode selected from the discoverable mode and the connectable mode based upon the activity of the device further comprises switching the mode to the connectable mode when the device is determined to be inactive.

6. The method of claim 1, wherein determining when the device is active and inactive further comprises determining when a screen associated with the device is active.

7. The method of claim 1, wherein determining when the device is active and inactive further comprises determining when a lid associated with the device is open.

8. The method of claim 1, wherein determining when the device is active and inactive further comprises determining when the device is key locked.

9. An apparatus for smart mode switching modes, comprising:

a display;

a wireless interface comprising a discoverable mode and a connectable mode; and

a processor configured to perform the following actions;

when the apparatus is powered on;

receiving a command from a user to select either a discoverable mode or a connectable mode relating to a wireless technology of a device;

wherein the discoverable mode allows the wireless device to be discovered by other Bluetooth wireless devices that are within range of the wireless device and wherein a partnership may be initiated with the wireless device once the wireless device is discovered and wherein the connectable mode allows only partnered Bluetooth devices to discover the wireless device;

determining when the received command indicates a selection of the discoverable mode; and

when the received command indicates the selection of the discoverable mode;

determine when the device is active;

determine when to switch the mode between the discoverable mode and the connectable mode based upon the determination of when the device is active;

wherein the mode is switched between the discoverable mode and the connectable mode while the device is powered on and while the device can determine user interaction; and

automatically switch the mode based upon the determination of when the device is active; and

determining when the received command indicates a selection of the connectable mode; and

when the received command indicates a selection of the connectable mode;

maintaining the device in the connectable mode when the device is both active and inactive.

10. The apparatus of claim 9, wherein determining when the device is active further comprises determining when the display is active.

11. The apparatus of claim 9, further comprising a lid;

wherein determining when the device is active further comprises determining when the lid is open.

12. The apparatus of claim 9, further comprising a keypad;

wherein determining when the device is active further comprises determining the keypad is locked.

13. The apparatus of claim 9, wherein the wireless interface supports Bluetooth.

14. The apparatus of claim 9, wherein automatically switching the mode based upon the activity of the device further comprises switching the mode to the discoverable mode when the device is active.

15. The apparatus of claim 9, wherein automatically switching the mode based upon the activity of the device further comprises switching the mode to the connectable mode when the device is determined to be inactive.

16. A system for smart mode switching, comprising:

a display;

a wireless interface configured to connect with other devices comprising a discoverable mode and a connectable mode; and

a processor configured to perform the following actions;

when the apparatus is powered on;

receiving a command from a user to select either a discoverable mode or a connectable mode relating to a wireless technology of a device;

wherein the discoverable mode allows the wireless device to be discovered by other Bluetooth wireless devices that are within range of the wireless device and wherein a partnership may be initiated with the wireless device once the wireless device is discovered and wherein the connectable mode allows only partnered Bluetooth devices to discover the wireless device;

determining when the received command indicates a selection of the discoverable mode; and

when the received command indicates the selection of the discoverable mode;

determine when the device is active;

determine when to switch the mode between the discoverable mode and the connectable mode based upon the determination of when the device is active;

wherein the mode is automatically switched between the discoverable mode and the connectable mode while the device is powered on and the processor can process user interaction; and

automatically switch the mode based upon the activity of the device; and

determining when the received command indicates a selection of the connectable mode; and

when the received command indicates a selection of the connectable mode;

maintaining the device in the connectable mode when the device is both active and inactive.

17. The system of claim 16, wherein the wireless interface supports Bluetooth.

18. The system of claim 17, wherein automatically switching the mode based upon the activity of the device further comprises switching the mode to the discoverable mode when the device is active.

19. The system of claim 18, wherein automatically switching the mode based upon the activity of the device further comprises switching the mode to the connectable mode when the device is determined to be inactive.
