Bluetooth Minimum Security Modes
IMPORTANT: bluetooth.minimum_security_mode sets the lowest security level at which the printer will
establish a Bluetooth connection. The printer will always connect at a higher security level if requested by
the master device.
The printers also feature bonding for Bluetooth. The printer caches pairing info so devices stay paired
through power cycles and disconnects. This eliminates the need to repair on every connection
establishment.
The
bluetooth.bonding SGD is on by default.

All Link-OS firmware versions prior to version 6.0
In all versions of Link-OS firmware prior to version 6.0, if bluetooth.discoverable is set to “on”, the
printer enters General Discoverable mode. It responds to discovery requests at any time, and is
connectable and pairable. If set to “off”, the printer is not discoverable, but it is still connectable and
pairable. The default was “on”.
Link-OS firmware version 6.0
If bluetooth.discoverable is set to “on”, the behavior is the same as pre-6.0 firmware. The printer
enters General Discoverable mode and is connectable and pairable. If set to “off”, the printer is not
discoverable, is still connectable and pairable. The default was changed to “off”. A new feature was added
to all printers called “Limited Pairing Mode” that turns on a limited discoverability and pairing window to
users who have physical access to the printer. If the user holds the feed key for 5 seconds, the printer
enters limited pairing mode for 2 minutes.
Link-OS firmware versions 6.1 and later
If bluetooth.minimum_security_mode is set to “1”, unconditionally enable pairing, regardless of the
bluetooth.discoverable mode setting. If bluetooth.minimum_security_mode is set to a value other
than 1, pairing is not allowed if discoverable is set to “off” and the printer is not in limited pairing mode.
NOTE: Discoverability does not apply to Bluetooth LE. For Zebra printers that support Bluetooth LE, the
bluetooth.discoverable setting affects pairing exact
