Chapter 2 — Configuring and Managing the SF51
SF51 Cordless Scanner User’s Guide 15
Configuring Bluetooth Communications
The SF51 can communicate with a host device through the
Serial Port Profile (SPP) Bluetooth communications profile.
SPP allows the SF51 to use the Bluetooth link as a serial port to
communicate with the host device. You can send information
from the SF51 to your serial application without having to
modify your application.
You can initiate a Bluetooth connection from either your SF51
or host device:
• If you initiate the connection from your SF51, you can only
connect one SF51 to your host device. When you reset the
SF51 by placing it in a charger, the SF51 automatically
reestablishes the Bluetooth connection.
• If you initiate the connection from a host device, you can
connect more than one SF51 to the same host device. When
you reset the SF51 by placing it in a charger, you need to
reestablish the Bluetooth connection from your host device.
Configuring Security
The SF51 provides Bluetooth wireless security for transmitting
data. By default, security is active on your SF51. For maximum
security, you need to configure a Bluetooth PIN (personal
identification number).
This section assumes that you have already installed EasySet
version 5.2 or later.
To configure a Bluetooth PIN for your SF51
1 Start EasySet version 5.2 or later.
2 In the Commands window, select Data transmission
settings > Bluetooth parameters > security.
3 Select active.
4 Select compose PIN and create a Bluetooth PIN that is up to
16 characters in length. The default Bluetooth PIN is 0000.
5 Scan both commands onscreen with your SF51, or print the
bar code setup sheet and scan both commands.
