Abstract

Disclosed are a hands-free device and a method of a hands-free device for automatic connectivity to two or more handheld devices. Upon power-up of the hands-free device, the device may cycle through all voice communication devices on its paired device list until it either cycles through the entire list or establishes a connection link before reaching the end of the list. It may then cycle through all non-voice communication devices on its paired device list. Once all voice and non-voice communication devices on the paired device list have been paged, the hands-free device may enter an idle mode where it is possible for a user to add a new device to the paired device list. The hands-free device may repeat the cycle through the voice communication devices in the paired device list, at a slower rate than the previous cycle through.

Claims

1. A method of a hands-free device, comprising:

determining a paired device list that includes at least one voice communication device and at least one non-voice communication device;

initiating short-range communication by paging for a first voice communication device that is the last-connected voice communication device of the paired device list;

initiating short-range communication by paging for a second voice communication device that is the next to the last-connected voice communication device of the paired device list in response to the paired device list containing two voice communication devices and in response to the unacknowledged paging for the first voice communication device;

initiating short-range communication by a paging for a first non-voice communication device that is the last-connected non-voice communication device of the paired device list;

wherein a rate at which paging for the first voice communication device is followed by at least one of the paging for the second voice communication device or the paging for a non-voice communication device is at a first predetermined rate.

2. The method of claim 1, further comprising:

discontinuing initiating short-range communication for an idle period after all voice communication devices of the paired device list have been paged.

3. The method of claim 2, wherein the idle period is approximately 20 seconds.

4. The method of claim 2, further comprising:

adding a new voice communication device to the paired device list during the idle period.

5. The method of claim 1, further comprising:

continuing initiating short-range communication by intermittent paging of at least one voice communication device of the paired device list at a second predetermined rate in response to a previously unacknowledged paging of a voice communication device of the paired device list and in response to an acknowledged paging of a non-voice communication device.

6. The method of claim 1, wherein initiating short-range communication by paging for a first non-voice communication device occurs after paging for all voice communication devices of the paired device list was unacknowledged.

7. The method of claim 1 wherein the first predetermined rate is 15 seconds between pages.

8. The method of claim 5 wherein the second predetermined rate is approximately between 10 seconds and 15 seconds between pages.

9. The method of claim 1 wherein the first predetermined rate is faster than the second predetermined rate.

10. The method of claim 1, wherein the voice communication device is a cellular telephone.

11. The method of claim 1, wherein the non-voice communication device is a music playback device.

12. The method of claim 1, wherein the non-voice communication device is a navigation system device.

13. A hands-free device, comprising:

a short-range transceiver for short-range communication;

a controller coupled to the short-range transceiver;

a determining module coupled to the controller and configured to determine a paired device list that includes at least one voice communication device and at least one non-voice communication device;

an initiating module coupled to the controller and configured to;

initiate short-range communication by paging a first voice communication device that is the last-connected voice communication device of the paired device list;

initiate short-range communication by paging a second communication voice device that is the next to the last-connected voice communication device of the paired device list if the paired device list contains two voice communication devices and if initiation of short-range communication with the first voice communication device fails; and

initiate short-range communication by paging a first non-voice communication device that is the last-connected non-voice communication device of the paired device list;

wherein;

a rate at which paging for the first voice communication device is followed by at least one of the paging for the second voice communication device or the paging for a non-voice communication device is at a first predetermined rate.

14. The device of claim 13, wherein the initiating module is further configured to discontinue initiating short-range communication for an idle period after all voice communication devices of the paired device list have been paged.

15. The device of claim 14, further comprising:

a pairing module coupled to the controller and configured to add a new voice communication device to the paired device list during the idle period.

16. The device of claim 13, wherein the initiating module is further configured to:

continue initiating short-range communication by intermittent paging of at least one voice communication device of the paired device list at a second predetermined rate if paging of a voice communication device of the paired device list was previously unacknowledged and if the paging of a non-voice communication device was acknowledged.

17. The device of claim 13, wherein the short-range transceiver is one of a Bluetooth transceiver and a WiFi transceiver.

18. A method of a hands-free device, comprising:

determining a paired device list that includes at least one voice communication device and at least one non-voice communication device;

initiating short-range communication by paging for a first voice communication device that is the last-connected voice communication device of the paired device list;

initiating short-range communication by paging for a second voice communication device that is the next to the last-connected voice communication device of the paired device list in response to the paired device list containing two voice communication devices and in response to the unacknowledged paging for the first voice communication device;

initiating short-range communication by a paging for a first non-voice communication device that is the last-connected non-voice communication device of the paired device list;

discontinuing initiating short-range communication for an idle period after all voice communication devices of the paired device list have been paged.

19. The method of claim 18, wherein discontinuing initiating short-range communication is at least one of automatic or manual.

20. The method of claim 19, further comprising:

adding a new voice communication device to the paired device list during the idle period.
