Interoperability
Interoperability refers to the ability of two
devices two communicate with each other.
Now, any Bluetooth device features one or
more applications, known as profiles. For one
Bluetooth device to be able to communicate
with another, the two devices must have at
least one shared profile. If, for instance, your
Bluetooth device features the profile object
exchange, you can exchange business cards
with any other Bluetooth device that has the
object exchange profile. Some other examples
of profiles are: cordless telephony, headset,
and file transfer.
Device discovery
When two or more Bluetooth devices are within
range, a link can be established. However, first
of all a Bluetooth device needs to discover the
other Bluetooth devices that are active within
its range. This operation is called device
discovery. When another Bluetooth device
responds, it supplies necessary information,
some of which concerns its identity: the device
name (eg. Adam) or the unique device address
(eg. 00:50:CD:3A:4B:69). A link can now be
established to the discovered device.
