Abstract

A power transmitting device may include at least one processor circuit. The at least one processor circuit may be configured to receive messages, such as advertising messages and/or scan response messages, from one or more power receiving devices. The messages may include device specific data that pertains to the corresponding power receiving devices that transmitted the messages. The device specific data may include, for example, data pertaining to the hardware, firmware, charging state, and/or device state of the corresponding power receiving device. The at least one processor circuit may be further configured to select one of the power receiving devices based at least in part on the device specific data contained in the messages. The at least one processor circuit may be further configured to initiate a connection to the selected one of the power receiving devices, such as a connection for wireless power transfer.

Claims

1. A method comprising:

receiving a plurality of advertising messages from a plurality of power receiving units, wherein at least some of the plurality of advertising messages comprise device specific data corresponding to at least some of the plurality of power receiving units;

selecting one of the plurality of power receiving units based at least in part on the device specific data of the at least some of the plurality of advertising messages; and

initiating a connection to the selected one of the plurality of power receiving units.

2. The method of claim 1, wherein the device specific data comprises at least one of a hardware version, a patch version, or a wireless power transfer vendor identifier.

3. The method of claim 2, wherein selecting one of the plurality of power receiving units based at least in part on the device specific data of the at least some of the plurality of advertising messages further comprises:

selecting one of the plurality of power receiving units for which at least one of the hardware version, the patch version or the wireless power transfer vendor identifier of the corresponding device specific data indicates that the one of the plurality of power receiving units is compatible for the connection to the power transmitting unit.

4. The method of claim 2, wherein initiating the connection to the selected one of the plurality of power receiving units further comprises:

initiating the connection to the selected one of the plurality of power receiving units utilizing at least a portion of the device specific data corresponding to the selected one of the plurality of power receiving units.

5. The method of claim 1, wherein the device specific data corresponding to each of the at least some of the plurality of power receiving units further comprises a boot state that indicates whether the each of the at least some of the plurality of power receiving units has initiated wireless charging.

6. The method of claim 5, wherein selecting the one of the plurality of power receiving units based at least in part on the device specific data of the at least some of the plurality of advertising messages further comprises:

selecting the one of the plurality of power receiving units for which the boot state of the corresponding device specific data indicates that the one of the plurality of power receiving units has not initiated wireless charging.

7. The method of claim 1, wherein the device specific data is further indicative of whether the selected one of the plurality of power receiving units requires a firmware update.

8. The method of claim 7, further comprising:

updating the firmware of the power receiving unit, prior to awakening a processor of the power receiving unit, when the device specific data indicates that the power receiving unit requires the firmware update.

9. The method of claim 1, wherein an advertising data type of the at least some of the plurality of advertising messages comprises a manufacturer specific advertising data type.

10. The method of claim 1, further comprising:

transmitting a scan request message; and

receiving a scan response message from at least one of the plurality of power receiving units, wherein the scan response message comprises the device specific data.

11. A power transmitting device, comprising:

at least one processor circuit configured to;

receive messages from power receiving devices, wherein each of the messages comprises device specific data pertaining to each of the power receiving devices;

select one of the power receiving devices based at least in part on the device specific data of the messages; and

initiate a connection to the selected one of the power receiving devices.

12. The power transmitting device of claim 11, wherein the messages comprise at least one of advertising messages or scan response messages.

13. The power transmitting device of claim 11, wherein the at least one processor circuit is configured to:

select the one of the power receiving devices for which the corresponding device specific data indicates that the one of the power receiving devices is compatible for the connection to the power transmitting device.

14. The power transmitting device of claim 11, wherein the at least one processor circuit is configured to:

select the one of the power receiving devices for which the corresponding device specific data indicates that the one of the power receiving devices has not initiated wireless charging.

15. The power transmitting device of claim 11, wherein the at least one processor circuit is configured to:

update a firmware of the selected one of the power receiving devices prior to awakening a processor of the selected one of the power receiving devices when the corresponding device specific data indicates that the firmware should be updated.

16. A computer program product comprising instructions stored in a tangible computer-readable storage medium, the instructions comprising:

instructions for formatting an advertising message;

instructions for determining an additional data format for the advertising message;

instructions for setting a first field of the advertising message to a version value associated with the determined additional data format;

instructions for inserting additional data into a second field of the advertising message, the additional data formatted according to the determined additional data format; and

instructions for transmitting the advertising message.

17. The computer program product of claim 16, wherein the instructions for formatting the advertising message comprises setting an advertising data field to a format value corresponding to a manufacturer specific advertising data type format.

18. The computer program product of claim 16, wherein the first field is a data version field, the second field is a data field, and a format of the data field corresponds to the version value.

19. The computer program product of claim 16, wherein the advertising message is transmitted to a power transmitting unit in a passive scanning mode or the advertising message is transmitted in response to an advertising information request from the power transmitting unit in an active scanning mode.

20. The computer program product of claim 16, wherein the additional data includes at least one of power chip information, a wireless power transmitter vendor ID, an over the air firmware update information, a boot state power supply, a patch version, and a hardware version.
