Bluetooth Application Quick Setup - Guide
Trouble shooting
Since the Bluetooth companion scanner don’t have displays, they also don't have a system menu to resort to when a
crashing application or OS prevents you from loading new software on the Bluetooth companion scanner.
For this reason the Bluetooth companion scanner have 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 Bluetooth companion scanner has
crashed or is constantly restarting due to a crashing application.
6.3 Restart mechanisms
The Bluetooth companion scanner have watchdog timers to determine
whether the OS is still running or has crashed. The watchdog timer will cause
the device to restart after 3 seconds if the OS has crashed. This watchdog
timer will not cause a restart when only the application has crashed.
The Bluetooth companion scanner have 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
both the trigger and delete key for at least 20 seconds. After the Bluetooth
companion scanner has sounded a short beep, you can release both keys to
complete the restart.
6.4 Halting your application
▪ Restart your application using one of the two restart methods listed above, but keep both keys pressed after the
short beep.
▪ Release the trigger key first to halt the application.
If successful, the LED of your Bluetooth companion scanner should now be blinking yellow/orange. You should now be
able to load new application or OS software.
To exit the halted application state, press both keys for 20 seconds
6.5 Halting the Operating System (only necessary in case a corrupt OS is installed)
▪ Restart your application using one of the 2 methods listed above, but keep both keys pressed after the short
beep.
▪ Release the clear key first to halt the Operating system.
If successful, the LED of your Bluetooth companion scanner should now be blinking red. You should now be able to
load a new OS.
To exit the halted Operating System state, press both keys for 3 seconds
