Software V3531x: OPN2002 Default Bluetooth Application

This application turns the OPN2002 into a Bluetooth barcode scanner, which currently supports the following features:
• Connecting to a remote device and transmitting its data using a Bluetooth virtual COM port (VCP) or as a Bluetooth Human Interface Device (HID)
• Making the OPN2002 connectable (as slave) and discoverable to allow a remote device to connect with the OPN2002 and transmit its data using a
Bluetooth virtual COM port (VCP) or as a Bluetooth Human Interface Device (HID)
• (Limited) Opticon Universal Menu Book support to configure barcode decoders, prefixes and suffixes, read modes, buzzer/LED settings, change Bluetooth
configurations and switch between HID or VCP Bluetooth interface
• Use of the trigger and clear key to connect, disconnect, make discoverable / connectable and reconnect
• iPhone / iPad compatibility
Note: source code will be available for editing by using the provided SDK.

Software V3553x: Advanced Bluetooth Application

This application has been developed for the OPR3301 barcode scanner, but it is also compatible with the OPN2002.
This application is very similar to the Bluetooth demo application (V3551x) listed above, but supports more of the Bluetooth options that are listed in the
Universal Menu Book.
This application is recommended when the OPN2002 is used as a replacement for the previous generation OPL2724 / OPL7724, and when barcode memorization
is desired such as when the OPN2002 has lost its Bluetooth connection or is out-of-range.
Note: no source code will be available for editing.
Since the OPN does not have a display, it also does not have a system menu to resort to when you have installed a crashing application that prevents you from
loading new software on the OPN200x.
For this reason, the OPN200x has a few escape mechanisms to allow you to restart, halt your application and/or install new software. This can be very useful in
case the OPN200x has crashed or is constantly restarting due to a crashing application.

Restart Mechanisms

Automatic The OPN has a watchdog timer to determine whether the OS is still running or has crashed. This watchdog will cause the OPN
to restart after three seconds if the OS has crashed. This watchdog timer will not cause a restart when only the application has
crashed.
Manually The OPN has a manual restart mechanism that allows you to restart in situations that the OS is still running, but the application
has crashed. In order to activate this mechanism, press and hold the trigger or delete key for at least 20 seconds. After the OPN
has sounded the restart beep, you can release the key to complete the restart.
Note: on the OPN2004, you must push both the trigger and clear key to halt the device. After the beep, if you release the trigger
key, the application will be halted, and you can reload it with Appload. If you release the clear key, the OS will be halted, and
you can reload it with Appload.

Halting the Application

• First, make sure your battery is not drained and your mini-USB cable is not connected to the OPN.
• Second, restart your application using one of the two restart methods listed above, while keeping the trigger key pressed.
• Finally, while keeping the trigger key pressed, insert the mini-USB cable into the OPN to halt the application.
If successful, the LED of your OPN should now be blinking orange. You should now be able to load new application or OS software.

Halting the Operating System

• First, make sure your battery is not drained and your mini-USB cable is not connected to the OPN.
• Second, restart your application using one of the two methods listed above, while keeping the delete key pressed.
• Finally, while keeping the delete key pressed, insert the mini-USB cable into the OPN to halt the operating system.
If successful, the LED of your OPN should now be blinking red. You should now be able to load a new OS.
