Not all devices need be INQUIRE-able. Some may not have INQUIRE scan 
enabled. In that case you need to know the Bluetooth address of the 
device you're looking for so you can PAGE it.
If you're expecting to see a mobile phone or other handheld device you 
might need to enable discoverability on the device itself. There are 
also other IAC codes used for INQUIRY, but generally these aren't used.
