Technology Profile Support
With Bluetooth Technology Profile Support, the cradle is not required for wireless communication. The scanner communicates directly
to the host using Bluetooth technology. The scanner supports the standard Bluetooth Serial Port Profile (SPP) and HID Profiles which
enable the scanner to communicate with other Bluetooth devices that support these profiles.
• SPP - the scanner connects to the PC/host via Bluetooth and performs like there’s a serial connection.
• HID - the scanner connects to the PC/host via Bluetooth and performs like a keyboard.
Master/Slave Set Up
The scanner can be set up as a Master or Slave.
When the scanner is set up as a Slave, it is discoverable and connectable to other devices. When the scanner is set up as a Master,
the Bluetooth address of the remote device to which a connection is requested is required. A pairing bar code with the remote device
address must be created and scanned to attempt a connection to the remote device. See the Pairing Bar Code Format on page 4-22
for information about creating a pairing bar code.
Master
When the scanner is set up as a Master (SPP or HID), it initiates the radio connection to a slave device. Initiating the connection is
done by scanning a pairing bar code for the remote device (see Pairing Bar Code Format on page 4-22).
Slave
When the scanner is set up as a Slave device (SPP or HID), the scanner accepts an incoming connection request from a remote device.
The number of scanners is dependent on the host’s capability.
Pairing Bar Code Format
When the scanner is configured as an SPP or HID Master, a pairing bar code must be created for the remote Bluetooth device to which
the scanner can connect. The Bluetooth address of the remote device must be known. Pairing bar codes are Code 128 bar codes and
are formatted as follows:
<Fnc 3>Bxxxxxxxxxxxx
where xxxxxxxxxxxx represents the 12-character Bluetooth address.
Pairing Bar Code Example
If the remote device to which the scanner can connect has a Bluetooth address of 11:22:33:44:55:66, then the pairing bar code is:
Paring Bar Code Content:
‘B’ + Bluetooth Address
B112233445566
