Selecting the correct interface and connection method
The OPR3301 can establish a Bluetooth connection and transmit its data in various
different ways.
The first step in determining which method is required in your specific application is
determining whether you want to receive the barcode data of the OPR3301 as serial
data (SPP) or as keyboard data (HID).
To make this selection, the following 2 defaults are supported *:
Bluetooth SPP
(default)
Bluetooth HID
* For easy-of-use all configuration labels in this manual can be read without reading the
traditional SET/END labels.
After reading one of the labels above, the OPR3301 will try to transmit its data to the
CRD-3301, which will then forward the barcode data as either serial data to the RS232
port of the CRD3301 or as keyboard data to its USB port.
However, the OPR3301 can also transmit its barcode data directly to a remote
Bluetooth device (like a PC, laptop or mobile device).
If you want to connect the OPR3301 directly with a Bluetooth device, first make sure
that this Bluetooth device supports the Bluetooth profile that you've selected. This
means that the manual of your Bluetooth device should explicitly state that it supports
either Bluetooth SPP or Bluetooth HID profile. (Some mobile devices, like the iPhone,
do have Bluetooth but don't support the SPP and HID profile)
Then next step is reading the label below to tell the OPR3301 it shouldn't connect to a
CRD3301, but to third party Bluetooth device.
Connect to PC
(or another third party Bluetooth device)
More labels to switch between the CRD3301 and a direct Bluetooth connection can be
found in Universal menu book chapter 2.3.1.
After configuring the interface and connection method it is now possible to connect your
OPR3301 to the CRD3301 or another Bluetooth device.
On the following pages various connection methods will be described depending on the
settings above and whether you want to actively connect your OPR3301 to a Bluetooth
device (master mode) or want a remote device to discover and connect to your
OPR3301 (slave mode).
