Abstract

A method of updating parameters of an embedded system through an object push profile (OPP) is used to update parameters of a Bluetooth-enabled device that does not have a keyboard. By using the OPP, a vCard is sent from an initiator to the embedded system, and a resolver extracts contents of fields of the vCard and stores the contents in a storage module. The contents are used to set a device name and a password of the Bluetooth device.

Claims

1. A method of modifying a plurality of parameters in an embedded device through an object push profile (OPP) used in an initiator comprising:

accepting a request to establish a transmission connection from the initiator;

obtaining a vCard sent by the initiator through the OPP over the transmission connection;

extracting a plurality of data fields from contents of the vcard; and

modifying the plurality of parameters based on the plurality of data fields.

2. The method of claim 1, wherein the initiator is a computer.

3. The method of claim 1, wherein the initiator is a mobile phone.

4. The method of claim 1, wherein the transmission connection supports infrared transmission.

5. The method of claim 1, wherein the transmission connection supports Bluetooth transmission.

6. The method of claim 1, wherein the plurality of data fields comprises a device name.

7. The method of claim 1, wherein a password sent by the initiator is accepted before obtaining the vCard sent by the initiator through the OPP over the transmission connection and before modifying the plurality of parameters based on the plurality of data fields.

8. The method of claim 1, wherein the vCard can be used to modify a password of the embedded system, the method further comprising:

extracting a new password data field from the vcard;

requesting the initiator to input a confirmation password corresponding to a value of the new password data field;

canceling a password modification process when the confirmation password does not match the new password data field; and

initiating the password modification process when the confirmation password matches the new password data field to replace the password with the value of the new password data field.

9. The method of claim 8, wherein a device name modification process can continue even if the password modification process is canceled.

10. The method of claim 1, wherein the embedded system is a Bluetooth headset.

11. An embedded system that uses an Object Push Profile (OPP) to modify parameters comprising:

a wireless transmitter module for receiving a request to establish a transmission connection from an initiator and for obtaining a vCard of the initiator by the OPP through the transmission connection;

a resolver module for extracting a plurality of fields from the vcard;

a storage module for storing a plurality of parameters of the embedded system; and

an updating module for updating the plurality of parameters based on the plurality of fields.

12. The embedded system of claim 11, wherein the initiator is a computer.

13. The embedded system of claim 11, wherein the initiator is a mobile phone.

14. The embedded system of claim 11, wherein the wireless transmitter module is an infrared transmitter.

15. The embedded system of claim 11, wherein the wireless transmission module is a Bluetooth transmitter.

16. The embedded system of claim 11, wherein each of the plurality of fields of the vCard comprises a device name.

17. The embedded system of claim 11, wherein the initiator inputs a pair of passwords that are confirmed before sending the vCard and updating the parameters.

18. The embedded system of claim 11, wherein the storage module is a non-volatile random access memory (NVRAM).

19. The embedded system of claim 18, wherein the NVRAM is an erasable programmable read-only memory (EPROM).

20. The embedded system of claim 18, wherein the NVRAM is an electrically erasable programmable read-only memory (EEPROM).

21. The embedded system of claim 18, wherein the NVRAM is a flash memory.

22. The embedded system of claim 21, wherein the flash memory is a NOR-type flash memory (NorFlash).

23. The embedded system of claim 21, wherein the flash memory is a NAND-type flash memory.

24. The embedded system of claim 11, wherein the embedded system is a Bluetooth headset.
