Wireless Communications with Bluetooth™
Bluetooth is a worldwide standard for the exchange of data be-
tween two devices via radio frequencies. Bluetooth radios are rela-
tively low powered to help prevent interference with other devices
running at similar radio frequencies. The range of a Bluetooth device
is approximately 10 meters (32 feet). Both the printer and the device it
communicates with must follow the Bluetooth standard.
Bluetooth Networking Overview
Each Bluetooth enabled EZ320 printer is identified by a
unique Bluetooth Device Address (BDA) loaded into the print-
er when manufactured. The printer BDA can be obtained from
the diagnostic report (see page 35). 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) must request a connection with another. The
second device (the slave) then accepts or rejects the connec-
tion. A Bluetooth enabled EZ320 printer will act as a slave
creating a Wireless Personal Area Network (WPAN) with the
terminal sometimes referred to as a “piconet.”.
About Bluetooth Security
The Bluetooth radio in this printer complies with the Bluetooth
specification 2.0 + EDR and therefore supports security modes 1, 2,
and 3. The end user can select the security mode at which the printer
will operate by configuring this parameter using Zebra Setup Utility
(ZSU).
• Security Mode 1 is non-secure. Authentication and encryp-
tion functionality are bypassed. The printer is shipped
with default Security Mode 1.
• Security Mode 2 is a secure mode that requires authen-
tication and encryption. This is considered a service
level-enforced security where security procedures are
initiated after the LinkManager Protocol (LMP) is es-
tablished. This is the host controller (radio module)
responsibility and happens at the lower layers of com-
munication including radio and baseband.
