Personal Area Networks
“Bluetooth” is the name given to a technology standard using short-range
radio links, intended to replace cables connecting portable and fixed electronic devices. The standard defines a uniform structure for a range of
devices to communicate with each other with minimal user effort. Its key
features are robustness, low complexity, low power, and low cost. The technology offers wireless access to LANs, the mobile phone network, and the
internet for a host of home appliances and mobile computer interfaces.
Wireless Printing can also be done with Microsoft APIs, including Bluetooth extensions for Winsock, and Bluetooth virtual COM ports. Information about other Bluetooth software is in the Bluetooth Resource Kit and
the Bluetooth Resource Kit User's Guide via the Intermec Developer Library
(IDL), which is available as a download from the Intermec web via
www.intermec.com/idl. See your Intermec representative for information.
Bluetooth is not started by default after a clean-boot is performed. You can
turn on Bluetooth doing either of the following:

Wireless Printing
Chapter 5 — Network Support
The Wireless Printing applet separates the task of wireless printing from
other Bluetooth management items not relevant to this task.
Wireless Printing has a concept of the “current wireless printer.” This
printer is the one to which the CN3 Computer makes a connection when
the wireless printing COM port is opened. If there is no current wireless
printer, there is no wireless printing COM port. Registration and deregistration of this COM port is controlled by the Bluetooth COM port control. Use the Wireless Printing applet to handle the COM port registration.
Customer software or other test applications can also use this applet to
manage the COM port registration and deregistration.
The current wireless printer is stored in the registry and is registered and
deregistered on Bluetooth stack load/unload. If the current wireless printer
changes, the existing wireless printing COM port is deregistered, and the
new one is registered instead. The registered COM port is stored in the registry as the “WPort.”
For information on using Bluetooth communications, see the Bluetooth
Resource Kit in the IDL, which is available as a download from the Intermec web site at www.intermec.com/idl. Contact your Intermec representa-
tive for more information.
Use any of the following methods to set the wireless printer:
• Use a Bluetooth device discovery to locate the remote device (page 105)

The CN3 Computer is a versatile mobile computer that you can add to
your wired or wireless data collection network. You can connect your CN3
Computer to your network using either the 802.11b/g radio or the Bluetooth radio.
Configuring 802.11b/g Radio Communications
The wireless CN3 Computer has an internal 802.11b/g radio to transfer
data using wireless communications. This section of the manual assumes
that you have already set up your wireless communications network including access points. If you are using a UDP Plus network, you also need to
have an Intermec Application Server communicating with a host computer.
Your CN3 Computer supports TCP/IP and UDP Plus network protocols.
The easiest way to configure the network parameters on the CN3 Computer is to use the Intermec Settings applet. See “Intermec Settings
Applet” on page 10 for more information.
Configuring the Network Parameters for a TCP/IP Network
In a TCP/IP network, the CN3 Computer communicates with a host computer directly using TCP/IP. The access point acts as a bridge to allow
communications between the wired and wireless networks.
Configuring the Network Parameters for a UDP Plus Network
In a UDP Plus network, the CN3 Computer communications with a host
computer through the Intermec Application Server. The Intermec Application Server translates UDP Plus packets on the wireless network into
TCP/IP packets on the wired network and vice versa. The access point acts
as a bridge to allow communications between wired and wireless networks.
