A Bluetooth communication system is provided wherein a remote, or destination, wireless communication device provides its Bluetooth profile information, including all of the necessary Service Discovery Protocol (SDP) information required to initiate a profile connection, to a source wireless communication device in an Extended Inquiry Response (EIR) message as part of Device discovery or Inquiry procedure. In response, the source wireless communication device will establish an ACL connection with the remote wireless communication device and provide its own EIR message containing the necessary SDP information of the source wireless communication device over ACL connection as an ACL data packet. The manufacturer data field of the EIR messages will include the SDP information of the respective devices. Thus the Bluetooth communication system preserves the overhead that would be expended in establishing a Layer Logical Link Control and Adaption Protocol layer (L2CAP) connection and exchanging multiple SDP requests and responses. |
