Understand Bluetooth Terms

SF61 Cordless Scanner User's Guide
The following terms are used in this User Guide:
Pairing: To be able to connect and exchange data with a Bluetooth
host device, your Bluetooth product must be "paired" with that
device. The way you authorize the pairing to take place depends on
the type of Bluetooth host device you are pairing with - see Chapter 2,
Connect the SF61B, for more details.
If your Bluetooth product and your Bluetooth host device are paired
but, for some reason, the connection cannot be established (your
product is out of range, one or both devices have been switched
off, ...), the pairing association is not lost and the devices can
communicate again when they are switched on and in range.
Discoverable: Your Bluetooth product is not yet paired with a
Bluetooth host device but it can be "seen" by that device (the
Bluetooth host device may also be able to "see" other Bluetooth
products that are nearby).
When your Bluetooth product is trying to connect or is connected to
a Bluetooth host device, it is no longer discoverable.
HID and SPP: Intermec Bluetooth scanners can use two specific
Bluetooth profiles to communicate with Bluetooth-enabled host
devices:
• HID: When you use the HID (Human Interface Device) profile,
your scanner is recognized as a keyboard by the host. Connection
information is stored so that if the scanner loses the connection
(out of range, low battery, etc.), it will try to reconnect as soon as
this becomes possible again (back into range, charged battery...).
No specific software is needed to collect data using the HID
profile (this is not the case if you use the SPP profile).
• SPP: The SPP profile (Serial Port Profile) allows your scanner to
communicate with the host device through the Bluetooth link as if
it were a serial port. In this way, your scanner is immediately
compatible with data management applications that collect data
through a serial port.
