Device Inquiry--The process of broadcasting a request
that all devices in range announce themselves. The
inquiry process will gather device addresses, Class of
Device, and valuable clock information from all de-
vices that respond to the inquiry. By default, a Device
Inquiry will last 10.24 seconds. This interval is speci-
fied by the Bluetooth specification and provides the
best opportunity to find all of the devices in range that
are set to discoverable.
Device Discovery--Is a Device Inquiry with the added
step of a Device Name Discovery.
Class of Device--Is information gathered during the
Device Discovery procedure and indicates a device's
type and what services it offers.
Bluetooth Device Class- Helps distinguish a particular
Bluetooth device from other devices that may be near.
Some Device Classes are Computer, Phone, and Audio.
The 781T has a Device Class of Peripheral.
Bluetooth Service Type--Helps distinguish a particular
Bluetooth service from other services that may be
near. Some Service Types are Networking, Capturing,
and Information. The 781T has a Service Type of Ren-
dering.
Discoverable --If your device is Discoverable, it re-
sponds to Device Inquiries from other devices. If you
have no need to gather information on a particular de-
vice, it is best to leave it as undiscoverable. A good ex-
ample is the 700. The 700 doesn't currently support
any services. If you make it discoverable, it will only
slow down the process of gathering information from
the printers that are in range.
Connectable --If your device is Connectable, it can ac-
cept requests for connection from other devices. If you
have no need to connect to a particular device, it is
best to leave it as unconnectable.
