GRYPHON™ I GD/GBT/GM4500
BLUETOOTH-ONLY FEATURES
The features in this section are valid only for Gryphon Bluetooth models.
Bluetooth Security Level
Set this parameter according to the security requirements of the application scenario
when the reader will be employed.
• Select Level 1 - lowest when the main application requirement is to avoid any user
interaction (e.g. Passkey or PIN entry) during the pairing process. When using this
setting, the resulting Bluetooth connection will be encrypted but not authenti
-
cated.
• Select Level 2 when encryption is required, authentication is not required, and
minimal user interaction is desired. In this case the Host may ask the user to enter
a 6-digit Bluetooth Passkey during the pairing process.
• Select Level 3 - highest when a secure connection to the Host is desired, with both
encryption and authentication. In this case the Host will ask the user to enter a 6-
digit Bluetooth Passkey or a Bluetooth PIN during the pairing process.
If the Host prompts the user to enter a Bluetooth Passkey or PIN code during the pairing
process, please refer to "
Bluetooth Passkey or PIN Code Entry Request" on page 25

form this task.
NOTE: Changing the configuration parameters described in this section may
cause a temporary loss of the Bluetooth connection between the Reader
and the remote device.
NOTE: This parameter applies when pairing the Reader with a third party
Bluetooth device. It has no effect when linking the Reader to a Base sta
-
tion.
NOTE: When device authentication takes place during the pairing process,
by means of the passkey or PIN entry, the resulting Bluetooth link is pro
-
tected from Man-In-The-Middle (MITM) malicious attacks.
NOTE: The actual behaviors of the Reader and of the Host system during
the pairing process depend on the security settings of both devices
involved, and on the input and output means available on each device to
interface with the user.
This means that:
• the user may be required to enter a BT Passkey during the pairing
process even if the reader’s BT Security Level is set to “Encryption
required, authentication not required”. This depends on the configu
-
ration of the Host system.
• when the reader’s BT Security Level is set to “Encryption and
authentication required”, it may not be possible to connect to a Host
system if the latter cannot support the Passkey Entry authentication
procedure. In this case, try to set the reader’s BT Security Level to
“Encryption required, authentication not required” to establish the
connection.
NOTE: Changing the BT Security Level setting will unlink the Reader from
the remote device.
