Sonic fast-sync method and system for bluetooth

Abstract

A method, apparatus and computer program product for fast-synching a wireless Bluetooth connection using a first device's wireless identifier is provided. One implementation of the present invention modulates the wireless identifier as a sonic Bluetooth code over a sonic carrier signal. To send the wireless identifier, one implementation accesses a storage area associated with the first wireless device holding the sonic carrier signal. Aspects of the invention then transmit the sonic Bluetooth code as modulated over the sonic carrier signal. A sonic transducer, such as a microphone on the second wireless device, receives the sonic carrier signal and wireless identifier for demodulation. In response, the second wireless device requests to establish a physical channel with the first wireless device using the wireless identifier received over the sonic carrier signal.

         3 . The method of  claim 2  wherein the exchange of messages occurs using at least a paging substate of the challenge-response protocol. 
     
     
         4 . The method of  claim 1  wherein modulating the data over the sonic carrier signal further comprises:
 encoding the data over one or more frequencies of the sonic carrier signal in accordance with a frequency-shift keying (FSK) protocol.
