4.6.2 Remote via Bluetooth
In some case it is very useful to be able to perform configuration remotely over a Bluetooth connection.
The
BluePort XP has this capability. To utilize it, connect to the device over Bluetooth and using a remote
terminal emulator, perform the same steps as you would for local configuration. When finished configuring
be sure to either reset the device or send the “---“ command, which will exit configuration mode and allow
data to pass normally.
NOTE: The BluePort XP firmware implements a configuration timer window, which defaults to 60 seconds
after power up. The device will ignore configuration attempts after this timer expires, and data will flow
back and forth in normal mode. The timer can be set to any value from 0 (disable remote configuration) to
0xFF hex, which allows continuous (no timeout) configuration.
WARNING: Configuration (local or remote) is NEVER enabled when the device is in auto-mode.
The unit must be in configuration mode to
remotely configure it via Bluetooth.

4.6.3 Security Issues, Pin Codes and Link Keys
If A> Blueport, or B> the remote device has authentication enabled, the following process occurs: The first
time a connection is made, a “passkey” is used. This is a series of numbers or characters, “1234” is the
default for the Blueport. Once this is entered, the remote Bluetooth device and the Blueport compare their
passkeys and if they match, a link key is generated, which is stored by the Blueport. Upon subsequent
connections, the devices will first compare link keys and if they are correct, no pin code will have to be re-
entered. If the remote device is a PC or PDA, a prompt is generally made to the user to enter this pincode.
To remove the stored link key on the remote device, generally you “unpair” with the Blueport. To remove
the link key on the Blueport, you can change the Pin Code. This will remove any previously stored link
keys from the blueport, forcing a new Pin Code exchange process to occur upon subsequent connection
attempts.
