CavitySearch is a Bash script which utilizes several methods of assessing the capabilities of Bluetooth devices. Most of the information can be gathered without pairing with the target device or alerting the end user. CavitySearch will report running services, Device Name, Device Address, Device Type, open RFCOMM Channels "ports", open L2CAP PSMs "ports", device manufacturer, supported protocols, and more. It is also able to help find "hidden" services running on the device.
