Understanding Bluetooth

Bluetooth is a wireless communication protocol that permits a small personal area network or
pico-net (small network) to be created among devices. Because it eliminates tethering the
devices together with a cord it can be very valuable as a connection technology, saving workers'
time untangling cords, decreasing maintenance costs associated with cord replacement, and
increasing overall workplace safety.
Bluetooth for scanning, printing and display on the A700/A700x devices uses the serial port
protocol. The Talkman
Bluetooth devices identify themselves by a unique 12 hexadecimal digit address, typically
specified in pairs of numbers separated by a colon (i.e. 08:00:2B:CF:3D:13). In order to initiate a
connection to a device this Media Access Control (MAC) address must be specified.

Bluetooth Range

Bluetooth is implemented in two ranges or classes, Class 1 (approximately 100 meters or 300
feet) and Class 2 (approximately 10 meters or 30 feet). Because Bluetooth operates within the
same frequency band, it can interfere with 802.11b/g wireless network traffic. Honeywell strongly
recommends exclusive use of Class 2 Bluetooth devices whenever possible.
CAUTION
Honeywell strongly cautions against the use of Class 1 Bluetooth devices because of their
potential to interfere with wireless network traffic over a very long range.

Bluetooth Device Roles

A Bluetooth device can function either as an acceptor of an incoming connection from a
corresponding initiator or as an initiator of an outgoing connection to a corresponding acceptor.

Bluetooth Security

Bluetooth devices support a security ID which typically may be enabled or disabled as an option.
This is useful mostly for devices that are deployed in a general population. Because of the limited
range of Bluetooth Class 2 devices, and the restriction of its use with a specific Vocollect device
application, it is unlikely that using or implementing this feature would provide value in typical
environments using the A700/A700x devices.
