Btscanner is a tool which extracts as much information as possible from a Bluetooth device without the requirement to pair. A detailed information screen extracts HCI and SDP information, and maintains an open connection to monitor the RSSI and link quality. btscanner is based on the BlueZ Bluetooth stack, which is included with recent Linux kernels, and the the BlueZ toolset. Using the information gathered from these sources it is possible to make educated guesses as to the host device type.

Nokia 6310i cellular phones (and possibly others like it) could be subject of a denial of service attack when invalid OBEX messages are sent to the phones' protocol handler. This attack results in the phone resetting, terminating any current operations. No device pairing is required therefore anyone in range of the phone could initiate an attack.
