Bluetooth Scanner Considerations

Honeywell recommends selecting Bluetooth scanners that:
Are class 2 devices, to limit any potential wireless network interference.
l
Support the Bluetooth Serial Port Protocol (SPP) for data transmission.
l
Do not require security options.
l
May be programmed easily via bar codes. Workers scan the bar codes in order to set up
l
scanners or reconfigure them to re-pair with different devices. This is much easier than
finding a supervisor when it is needed to edit a static configuration in VoiceConsole.
In applications using several scanners, Honeywell recommends associating (pairing) the reader
with its base unit during idle periods, or turning it off. Typically, pairing with the charging base is
done by scanning the bar-code at the reader's charging base or a code break (unpair) the
connection. Unconnected Bluetooth devices that are still logically paired will often 'page' to try to
re-pair. This can create significant increases in Bluetooth activity and possibly impact wireless
network performance. Ensuring that unused active devices are always paired reduces this
possibility

Bluetooth Printer Considerations

Bluetooth printers typically will function as acceptors. Unlike scanners which allow input via bar
codes, printer configuration is frequently done with special management software with only
limited controls available to the worker.
When planning to implement Bluetooth printers, consider permanently associating or pairing
each printer with a specific device to avoid the need for management intervention to reassign
printer pairing with devices.

Basic Bluetooth Roles and Concepts

Pairing: Pairing is the process in which two devices enabled with Bluetooth wireless technology
create a secure link in order to share information. Each of the two devices is configured in a
different pairing mode. These modes are:
Acceptor – the device configured as an acceptor will accept a connection from the other
l
device. It will not attempt to actively connect to any other device. It may require some
security information from the initiator device before accepting the connection.
Initiator – the device will actively search for (page) and connect to the other device (which
l
must be discoverable and configured as an acceptor). If security settings have been
configured on the initiator device, it may need to present these settings to the acceptor to
complete the connection.
The pairing process begins when the initiator device broadcasts an inquiry to search for
discoverable Bluetooth addresses of acceptor devices.
MAC address: Bluetooth devices such as scanners are identified by a unique 12 hexadecimal
(base 16) address (i.e. composed of the numbers 0-9 and letters A-F, typically expressed in pairs
