Wireless Communications with Bluetooth
Bluetooth is a worldwide standard for the exchange of data be-
tween two devices via radio frequencies. This form of point- to-
point communication does not require access points or other
infrastructure. Bluetooth radios are relatively low powered to help
prevent interference with other devices running at similar radio
frequencies. This limits the range of a Bluetooth device to about
10 meters (32 feet). Both the printer and the device it communi-
cates with must follow the Bluetooth standard. Other than con-
ditions specified elsewhere in this manual, only one of the radio
options can be installed in the printer at one time and the anten-
na used for these transmitters must not be co-located or must not
operate in conjunction with any other antenna.
Bluetooth Networking Overview
Each Bluetooth enabled ZQ500 Series printer is identified by
a unique Bluetooth Device Address (BDADDR). This address re-
sembles a MAC address whereby the first three bytes are ven-
dor, and the last three bytes are device (e.g. 00:22:58:3C:B8:CB).
This address is labeled on the back of the printer via a barcode
for ease of pairing. (See Page 34.) In order to exchange data, two
Bluetooth enabled devices must establish a connection.
Bluetooth software is always running in the background, ready
to respond to connection requests. One device (known as the
master or the client) must request/initiate a connection with an-
other. The second device (the slave or the server) then accepts or
rejects the connection. A Bluetooth enabled ZQ500 Series printer
will normally act as a slave creating a miniature network with the
terminal sometimes referred to as a “piconet”.
Discovery identifies Bluetooth devices that are available for pair-
ing whereby the master device broadcasts a discovery re- quest
and devices respond. If a device is not discoverable, the master
cannot pair unless in knows the BDADDR or has previously paired
with the device.
Bluetooth 2.1 or higher uses Security Level 4 Secure Simple
Pairing (SSP), a mandatory security architecture that features four
(4) association models: Numeric Comparison, Passkey Entry, Just
Works (no user confirmation), and Out of Band (pairing info trans-
mitted OOB, e.g. via Near Field Communication).
