Bluetooth wireless connections explained
The GeoExplorer 2008 series handheld has an integrated Bluetooth radio that you can
use to establish a wireless connection to other Bluetooth devices that are within range.
Using a Bluetooth connection, you can communicate with devices such as cellular
phones, office computers, other handhelds, and Bluetooth-enabled laser rangefinders
and barcode scanners. You can also communicate with peripheral devices that use
Bluetooth adaptors instead of serial or USB connections.
The GeoExplorer 2008 series handheld can act as a Bluetooth client device or a
Bluetooth host device, and can act as both at the same time. The concepts of client and
host devices are explained in detail below.
Connecting to a Bluetooth device as a client
You can use the GeoExplorer 2008 series handheld as client device, which uses
services offered by Bluetooth host devices that are within range. In general the host
device provides information to the client device, but in some cases the client initiates
the connection and also provides information to the host device.
The services used by a GeoExplorer 2008 series handheld when connecting as a
Bluetooth client are:
A client can connect to a number of different services provided by different hosts. The
number of active connections at any one time affects the speed of the connections.
