Juno Series User Guide 95
Getting Connected 6
Bluetooth wireless connections explained
The Juno 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 Juno 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 Juno 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 Juno 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.
Figure 6.1 shows the handheld connected to different types of host devices using
Bluetooth wireless technology.
