Understanding Bluetooth

Bluetooth Characteristics

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 and printing on T5 Series or T2 Series devices uses the serial port

protocol. Talkman T5 series uses a compressed data protocol to provide quality speech

recognition and requires the use of an SRX headset. (Off-the-shelf headsets will not function

with Talkman T5 series systems.)

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 100meters or 300

feet) and Class 2 (approximately 10 meters or 30 feet). Because Bluetooth operates within

the same frequency band, it can interfere with 802.11 wireless network traffic. Vocollect

strongly recommends exclusive use of Class 2 Bluetooth devices whenever possible.

Important Note: Vocollect strongly cautions against the use of of Class 1 Bluetooth

devices because of their potential to interfere with wireless network traffic over a

very long range.

Bluetooth Device Roles

Bluetooth devices 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 mostly useful for devices that 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 computer application, it is unlikely that using or implementing this feature would

provide value in typical environments using T5 Series or T2 Series devices.

Bluetooth Scanner Considerations

Vocollect recommends selecting Bluetooth scanners that are:

 Class 2 devices, to limit any potential wireless network interference.

 Support the Bluetooth Serial Port Protocol (SPP) for data transmission.

 Do not require security options.
