Find Bluetooth Devices
Search for Devices looks for Bluetooth devices in the vicinity and displays the de-
vices that it finds in My Bluetooth Places.

To start a search for devices, in the Folders pane of My Bluetooth Places, select
Entire Bluetooth Neighborhood, and then, from the Bluetooth menu, select Search for
Devices.
NOTE: The Bluetooth menu is visible only when My Bluetooth Places is active.
5.1 Periodic Search For Devices
Bluetooth can be configured to search automatically for devices on a regular basis
(Bluetooth Configuration Panel > Discovery tab).
One of the advantages of Bluetooth is the mobility that the wireless connections allow.
However, mobility means that devices may move in or out of connection range during
the time between the automatic updates performed by Bluetooth. To be certain that
the displayed list of devices in the neighborhood is current, or if automatic periodic
inquiry is not enabled, force an update of the device list using the technique described
in Search for Devices, above.
Some devices within connection range may not show up in the list of devices
found because:
‧ Your device is configured to report only specific types or classes of devices
(Bluetooth Configuration Panel > Discovery tab, on your device).
‧ The unlisted device is configured to be non-discoverable. Refer to the unlisted
device’s documentation for assistance in making that device discoverable.
NOTE: If you enable the periodic search for devices feature you may experience
some performance degradation while the search is in process, depending on the type
of system you have.
5.2 Find A Service
The process of determining the services that a device provides is called Service
Discovery.
To initiate a Service Discovery, in the Folders pane of My Bluetooth Places, right-
click a device name and select Discover Available Services from the shortcut menu.
Bluetooth services are those things that this computer can do for remote Bluetooth
devices. For example, if this computer allows a remote Bluetooth device to send a fax
using a fax modem that is physically attached to this computer, then this computer is
providing the Bluetooth fax service.
Some services are hardware dependant; this computer cannot provide the fax service
unless it has a physical fax modem, for example.
Some Bluetooth services use virtual “hardware.” The Bluetooth Serial Port service, for
example, does not use a physical port on this computer. Instead, it creates virtual
serial ports that Windows applications can see and use as if they were actual physical
ports.
Each Bluetooth service that this computer is capable of providing can be started
automatically when Bluetooth starts. Each service can be setup to require security
measures before allowing a remote Bluetooth device to connect.
