Figure 6.1 GeoExplorer 2008 series handheld Bluetooth client connections
In Figure 6.1, the dashed arrows indicate the client device—that is, the GeoExplorer
2008 series handheld—connecting to host devices. The Bluetooth profile (or service)
used for the connection is shown between the arrows, for example, the DUN service is
used for a connection to a cell phone, and the Serial Port service is used for a serial
connection to a GeoBeacon receiver or laser rangefinder.
The solid arrows indicate the flow of information between devices. For example, when
the GeoExplorer 2008 series handheld connects as a client to:
• a cellphone, the handheld uses the DUN or PAN host service provided by the
phone to access the Internet and receive real-time differential corrections or
background map data.
• a laptop computer or office computer, the devices use the ActiveSync service to
exchange information to and from either device.
• Bluetooth headphones, the handheld uses the Wireless Stereo host service
provided by the headphones to play audio files and system sounds.
