Find A Service
The process of determining the services that a device provides is called Service Discovery.
To initiate a Service Discovery, in My Bluetooth Places, right-click a device name and then, from the shortcut
menu, select Discover Available Services.
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; for example, this computer cannot provide the fax service unless it
has a physical fax modem.
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.
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.
The services supported by Bluetooth are:
• Bluetooth Imaging - allows a remote device to send and receive images (BMP, GIF, PNG, & JPG) to this
computer. Images are stored in the Bluetooth exchange folder.
• Bluetooth Serial Port - allows 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 their 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 a 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 only
provide the Network Access service.
