Chapter 2 — Configuring and Managing the SF51
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
1Start EasySet version 5.2 or later.
2In the Commands window, select Data transmission settings > Bluetooth parameters > security.
3Select active.
4Select compose PIN and create a Bluetooth PIN that is up to 16 characters in length. The default Bluetooth PIN is 0000.
5Scan both commands onscreen with your SF51, or print the bar code setup sheet and scan both commands.
