(Sorry for the inconvenience)
Beginning with version 9.1, PC-BSD includes a Bluetooth Manager in the system tray. This utility can be used to simplify the pairing of devices and provides a graphical front-end to FreeBSD's hcsecd(8) daemon which controls link keys and PIN codes for Bluetooth devices.
Since the developers do not have access to every possible Bluetooth device, it is possible that your device will not be recognized. If this is the case, please take the time to send the details about the device to the testing mailing list so that the developers can work with you to fix the issue.
