Connecting the OPR3301 as master
Depending on the Operating System and Bluetooth stack of your PC, laptop or mobile
Bluetooth device, it is often necessary to first open the (incoming) Bluetooth Virtual
Com port, before you will be able to connect your OPR3301 as master to your device.
Using applications like Hyperterminal or the RS232 monitor of Appload it is possible to
open the (incoming) Bluetooth Virtual Com Port. For more information on how to open
a COM port, please refer to documentation of your remote Bluetooth device.
The first time you try to connect your OPR3301 to a Bluetooth device you will have to
scan the created Bluetooth address label. Once the Bluetooth address is configured, it
will also be possible to do a connection attempt by pressing the trigger key for 5
seconds.
If you haven't disabled authentication on your remote device, then you will be
requested to enter a PIN code (passkey). The default PIN code of the OPR3301 equals
the last 4 digits of the Bluetooth address. These last 4 digits of the Bluetooth address
are also shown in the Bluetooth name of the OPR3301. If you wish to use a different
PIN code, then this is possible by using the 'Set/End PIN-code' menu labels, which can
be found in chapter 2.3.2 of the Universal menu book.
Example of a request on a Windows device to enter a PIN-code (passkey)
When executed correctly your OPR3301 should now be connected as Virtual Com port
to your remote device and you should be able to scan and transmit barcodes as serial
data.
If you've lost your connection or closed the virtual COM port, then the OPR3301 will try
to reconnect for 5 minutes (by default). You can also reconnect manually by pressing
the trigger key for 5 seconds, read the Bluetooth address label again or by reading the
CONNECT label (see chapter 2.3.1 of the menu book).
To manually end your connection you can scan the DISCONNECT label (see chapter
2.3.1 of the menu book). It is also possible to disconnect by pressing the trigger key by
configuring a 'trigger-to-disconnect' time (see Chapter 2.3.4. of the Universal menu
book).
