6 Trouble shooting & additional features
6.1 Bluetooth connection problems
If problems occur during the disconnecting and (re)connecting process, this can have
various causes and solutions.
• Barcode reader
o Try resetting the application to default (see chapter 1)
o Reset the OPN2002 by pressing the large button for 20 seconds
o Check if there are software updates available for either the OS or
application on your barcode reader. (See chapter 6.3)
• OpticonRL
o Check if there are software updates available for OpticonRL on the
Android market
o If regular reconnect problems occur, disabling the ‘Enable auto
connect’ option can solve issues on certain Android phones
o When switching between two barcode readers on the same phone, it
can help to remove the pair of the first reader before trying to connect
with the other.
o If OpticonRL is no longer function, rebooting your phone will cause
OpticonRL to be restarted.
• Android Bluetooth software
o Try turning Bluetooth off and on again on your phone and then try to
reconnect.
o Remove the pair with your barcode reader and try pairing again
o If everything else fails, try rebooting your phone
6.2 Minimum required OS version of the OPN2002
In order to make your OPN2002 work correctly with your Android phone, it is
recommended to use the latest available Bluetooth demo application (RFG35312 or
higher) and use a recent OS version (RBGV0215 or higher). These two files comprise
the embedded firmware of the OPN2002.
If you want to check the currently installed OS and application version it is possible
to transmit both versions by USB-VCP by reading the 'Z1' menu label (See Universal
menu book chapter 7). It's also possible to use Appload (Utilities > Show software
version) to check the OS version.
6.3 Software updates for the OPN2002
In the future more features and bug fixes are likely to be implemented into the OS of
the OPN2002 and this application. To find out if there are software updates available,
please check our web site. All available software and documentation for the OPN2002
can be found under:
'Service and support' > 'Software' / 'Manuals' > 'OPN2002' at www.opticon.com.
