Software locking via access code in SmartBlue
The configuration data can be write-protected using an access code (software locking).
‣
Navigate to: Setup → Advanced setup → Administration → Administration1 → Define
access code → Confirm access code
The new access code must differ from the last access code used and may not be "0000".
• The access code is only active if a different (wrong) code is entered or the device is
deenergized.
• Once the access code has been defined, write-protected devices can only be switched
to maintenance mode if the access code is entered in the
Enter access code
parameter. If the factory setting is not changed or if "0000" is entered, the device is
in maintenance mode and its configuration data are therefore
not
write-protected
and can be changed at any time.

Unlocking via SmartBlue
‣
Navigate to: Setup → Advanced setup → Access status tooling → Enter access code

Bluetooth® wireless technology
Signal transmission via Bluetooth® wireless technology uses a cryptographic
technique tested by the Fraunhofer Institute
• The device is not visible via
Bluetooth
® wireless technology without the SmartBlue app
• Only one point-to-point connection between
one
sensor and
one
smartphone or tablet is
established
• The
Bluetooth
® wireless technology interface can be disabled via SmartBlue, FieldCare
and DeviceCare
Disabling the Bluetooth® wireless technology interface
‣
Navigate to: Setup → Communication → Bluetooth configuration → Bluetooth mode
Switch off the
Bluetooth
® wireless technology interface. "Off" position disables
remote access via app
Re-enabling the Bluetooth® wireless technology interface
If the
Bluetooth
® wireless technology interface has been disabled, it can be re-enabled via
FieldCare / DeviceCare at any time
The
Bluetooth
® wireless technology interface is restarted 10 minutes after the device is
switched on.
‣
Navigate to: Setup → Communication → Bluetooth configuration → Bluetooth mode
Switch on the
Bluetooth
® wireless technology interface. "On" position enables
remote access via app
Bluetooth recovery sequence
The
Bluetooth
® wireless technology interface can be re-enabled after performing the
following recovery sequence:
1. Connect device to voltage supply
After a waiting time of 10 minutes, a time window of 2 minutes opens
2. You can re-enable the
Bluetooth®
wireless technology interface of the device using
the SmartBlue (app) during this time window
3. Navigate to: Setup → Communication → Bluetooth configuration → Bluetooth mode
Switch on the
Bluetooth
® wireless technology interface. "On" position enables
remote access via app
