Abstract

A method for use by a device communicating according to a short-range wireless connectivity protocol in attempting to establish a connection to another device using an enhanced inquiry and/or paging procedure as part of the connection procedure, the method including a step in which the device transmits a first packet for establishing a connection to the other device, and the other device responds with one or more response packets whose content depends on whether the other device is configured to perform the enhanced procedure. In some embodiments, the first packet is an identifier packet including extension data indicating via a predetermined bit pattern that the device is itself configured to perform the enhanced procedure.

Claims

1. Apparatus, comprising:

a packet transmitting module, configured to transmit an identifier packet according to a short-range wireless protocol; and

a packet receiving module, configured to receive one or more response packets from a device, and for using the content of the one or more response packets to determine whether the device is configured to perform an enhanced procedure,

wherein the apparatus is an inquirer apparatus or a paging apparatus and the one or more response packets include a synchronizing packet, wherein the one or more response packets include synchronizing information per a non-enhanced procedure followed by additional data per the enhanced procedure.

2. Apparatus, comprising:

a packet receiving module, for receiving from a device a packet according to a short-range wireless discovery protocol; and

a packet transmitting module, for transmitting one or more response packets to the device with content useable by the device for determining whether the apparatus is configured to perform an enhanced procedure,

wherein the apparatus is configured to convey as the one or more response packets synchronizing information per a non-enhanced procedure followed by additional data per the enhanced procedure.

3. Method, comprising:

transmitting, from a packet transmitting module of an apparatus, an identifier packet according to a short-range wireless protocol, and

receiving, in a packet receiving module of the apparatus, one or more response packets from a device, and using the content of the one or more response packets to determine whether the device is configured to perform an enhanced procedure,

wherein the apparatus is an inquirer apparatus or a paging apparatus and the one or more response packets include a synchronizing packet, wherein the one or more response packets include synchronizing information per a non-enhanced procedure followed by additional data per the enhanced procedure.

4. Method, comprising:

receiving, in a packet receiving module of an apparatus, a packet from a device according to a short-range wireless discovery protocol, and

transmitting, from a packet transmitting module of the apparatus, one or more response packets to the device with content useable by the device for determining whether the apparatus is configured to perform an enhanced procedure,

wherein the apparatus is configured to convey as the one or more response packets synchronizing information per a non-enhanced procedure followed by additional data per the enhanced procedure.
