Honeywell International Inc. SF61B-A Manuale Utente

Choose the appropriate Bluetooth profile to communicate with your 
host device (a Bluetooth-enabled PC for example) depending on the 
requirements of your data management application:

HID (Human Interface Device Profile) emulates keyboard data 
entry

SPP (Serial Port Profile) emulates data acquisition through a 
virtual COM port.

With the HID (Human Interface Device) profile, your SF61B is 
recognized as a keyboard. No specific software is needed to collect 
data using the HID profile (this is not the case if you use the SPP 
profile).

When you pair using the HID profile, you connect straight away 
directly with the host.

The SPP profile (Serial Port Profile) allows your SF61B to communicate 
with the host device as if the Bluetooth link was a serial port. In this 
way, your SF61B is immediately compatible with data management 
applications that collect data through a serial port.

When you pair using the SPP profile, you do not connect straight 
away with the host, you must then connect with your host application 
either through an Outgoing (host-initiated) SPP connection or 
through an Incoming (scanner-initiated) SPP connection.

You can connect to your Bluetooth device using one of the following 
Bluetooth connections:

HID connection (host initiated)

SPP outgoing connection (host initiated)

SPP incoming connection (scanner initiated)
