App settings

This section describes the application-level settings available in PicoKeyApp. These settings affect how the application communicates with PicoKey devices and how certain advanced features are enabled.

Application settings

Available readers

Selects the smart card / USB reader interface used by PicoKeyApp.

  • The list shows all detected compatible interfaces
  • The active reader is highlighted
  • The refresh button forces a new scan of available readers

Note

In most cases, the default reader selection is sufficient and should not be changed.

Force Rescue Interface

Forces the application to use the Rescue Interface instead of the default PC/SC interface.

When enabled:

  • PicoKeyApp bypasses the standard PC/SC stack
  • Communication is performed through the Rescue Interface
  • This may be required if PC/SC is misconfigured or unavailable

Warning

The Rescue Interface provides reduced functionality compared to PC/SC.

Patch PC/SC

Attempts to patch the local pcscd service to improve compatibility with PicoKey devices on some Linux distributions.

When enabled:

  • PicoKeyApp applies changes to the PC/SC service
  • Compatibility issues with certain distributions may be resolved

Danger

This operation requires root privileges and may affect other smart card devices. Use with caution.

Agent

Enable Agent

Enables communication with PicoKey Agent.

When enabled:

  • The device can communicate with the local PicoKey Agent
  • Advanced operations become available

  • Required for features such as:

  • Device time synchronization

  • Audit or traceability features

Note

PicoKey Agent runs as a background service and must be installed separately.

Device status indicators

At the bottom of the application, PicoKeyApp displays real-time status information:

  • Device connection status (online/offline)
  • Recovery mode state
  • Current device time

Tip

Device time is updated automatically when the agent is enabled.
