BlueScanner

What is it:

BlueScanner is an application which is designed for mobile devices. The surrounding area will be scanned for other visible Bluetooth devices and as many as possible information will be retrieved, e.g. which services are running (see illustration) and so on...
Through the fingerprint of the Bluetooth address, the BT chipset manufacturer can be found in the internal database which has about 10,670 entries (see also IEEE, http://standards.ieee.org/regauth/oui/oui.txt).
This application is licensed under the GNU/GPL v2 license and can simply be uploaded to your phone or pda/handheld.
