Article Number: #20006 Version 2.0 All specifications and information are subject to changes without further notices 9 The services supported by Bluetooth™ are: • Bluetooth™ Serial Port-a wireless connection between two devices. This connection can be used by applications as though a physical serial cable connected the devices. • Dial-up Networking-allows a device to use a modem that is physically attached to another Bluetooth™ device. • Fax-allows a device to send a fax using a remote Bluetooth™ cell phone, modem, or computer. • File Transfer-allows a device to perform file system operations on another Bluetooth™ device; browse, open, copy, etc. • Headset-allows a Bluetooth™ headset to be used as the audio input/output mechanism for another Bluetooth™ device, such as a computer or cell phone. • PIM Item Transfer-allows two Bluetooth™ devices to exchange Personal Information Manager data such as business cards, calendar items, email messages, and notes. • PIM Synchronization-allows two Bluetooth™ devices to synchronize Personal Information Manager data. • Network Access-allows a device to access a Local Area Network via a second Bluetooth™ device that is physically connected to the network or allows a remote device to become part of an ad hoc network provided by the Bluetooth™ server. • Audio Gateway-allows the microphone/speakers on Bluetooth™ device (typically a computer) to be used as the audio input/output mechanism for a remote Bluetooth™ device, such as a cell phone. All Bluetooth™ servers do not necessarily provide all of these services. For example, network gateways may provide only the Network Access service. 3v. FIND A SERVICE The process of determining the services that a device provides is called Service Discovery. You can follow the wizard's on-screen instructions to find a service to use or click "Skip" button to skip this step. 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

Article Number: #20006 Version 2.0 All specifications and information are subject to changes without further notices 10 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. Bluetooth™ services require a Bluetooth™ application on the remote device; services and applications usually have coinciding names; i.e., there is a Bluetooth™ Fax Service and a Bluetooth™ Fax Application. 3vi. To confirm if the Bluetooth™ device installed is properly. From the Bluetooth™ menu, select "Advanced Configuration". Under the "Hardware" tab, verify the Bluetooth™ address is present along with the driver and firmware version info. If such information is not present, please unplug then plug in the USB adapter to initiate the driver. For CF Bluetooth™ card, please reboot the system with the CF Bluetooth™ card securely inserted in the PCMCIA slot. Repeat the installation steps for other USB adapters or CF card on other PCs. 3vii. Periodic 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. - end of Bluetooth™ software installation section -
