2.5FIND BLUETOOTH DEVICES

Search for Devices looks for Bluetooth devices in the vicinity and displays the devices 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 only visible when My Bluetooth Places is active.

2.5.1Periodic Search for Devices

Bluetooth can be configured to automatically search 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 (Bluetooth Configuration Panel > Accessibility tab, on the un-listed device).

2.6FIND 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 set up to require security measures before allowing a remote Bluetooth device to connect.
