Bluetooth
is a global standard for wireless connectivity for digital devices and is intended for Personal Area
Networks (PAN). The technology is based on a short-range radio link that operates in the ISM band at 2.4 GHz.
When two Bluetooth-equipped devices come within a 10 metre (32 ft.) range of each other, they can establish a connection. Because Bluetooth utilizes a radio-based link, it does not require a line-of-sight connection in order to communicate.
Keep in mind that Bluetooth and IEEE 802.11g radios both operate in the 2.4GHz band. Although the Workabout Pro4 includes features to minimize interference, performance of the system will not be optimal if you use both radios simultaneously. Typically, when both radios operate in the hand-held at the same time, they cannot transmit simultaneously — this has a negative impact on overall system throughput. To minimize the impact on the backbone 802.11 network, Zebra recommends using Bluetooth peripherals that have low transaction rates
(such as printers and scanners).
Bluetooth
peripherals are configured by choosing the Bluetooth icon in the Control Panel. In addition, review the manual shipped with your Bluetooth device to determine the method used to associate with the
Workabout Pro4 host.
NOTE
The Bluetooth radio uses an internal antenna.
• In the Start>Settings>Control Panel, choose the Bluetooth icon to display the Bluetooth Manager screen.
The Bluetooth Manager allows users to search, pair and connect to other Bluetooth devices within their personal area network.
The Bluetooth radio is disabled by default. Before you begin the setup process:
• Tap on the Mode tab, and tap in the check box next to Turn on Bluetooth. Tap on OK.

Servers
When a remote Bluetooth device initiates a Bluetooth connection to the Workabout Pro4, the remote device is considered the Bluetooth master and the hand-held, the Bluetooth slave. In order for the remote device to connect to the hand-held, the Workabout Pro4 must offer a service in the form of a server. The Servers tab allows these services to be enabled and configured. There are three server services available: Serial, Scanner and OBEX OPP.
Serial
server enables the Serial Port Profile server; a Serial Port can be selected from the drop-down menu.
You can assign either a BSP or a COM prefix from the drop-down menu. BSP (Bluetooth Serial Port) was created by Microsoft to allow Bluetooth to have its own serial prefix in order to free up virtual COM prefixes as these are limited and are widely used.
NOTE
Even after a Serial Port Profile server is created, an application must open the created port before a remote device can connect.
Scanner
server enables a Serial Port Profile server and then relays it to the Scanner Service (SCS). This is used for Bluetooth barcode scanners that operate in client mode. SCS opens the server port and handles the scanner input.
OBEX OPP
server enables the Object Push Profile server. A warm reset must be performed on the Workabout
Pro4 after a change is made to this option. The OPP Server allows other Bluetooth devices to send files to this device.
• Tap on the check box to activate the server.
Mode
Configuration 3 - 13
Turn on Bluetooth
activates the Bluetooth radio.
Discoverable
determines whether the Workabout Pro4 is visible or invisible to other devices.
Printer Port
allows you to assign and enable a virtual outgoing COM port selected from the drop-down menu to communicate with a paired Bluetooth printer. Keep in mind that when a port is chosen, the printer must be on and connected to the chosen port for a remote device to be able to connect.
• Select a port within the Printer Port drop-down list, e.g. BSP1:
• Check the Printer Port check box.
• Open the Device tab and tap on Scan.
• Tap-and-hold each Bluetooth Printer device entry and then select Pair, key-in the Pass code (if needed) and then tap Done. DO NOT select any services!
• Close the Bluetooth Manager.
• Select the Bluetooth device to print to — you will need to key-in (or programmatically raise) the following key sequence [CTRL] [ALT] [F1].
• You can now select the Bluetooth device to which you wish to print.
