Bluelog is a Bluetooth site survey tool, designed to tell you how many discoverable devices there are in an area as quickly as possible. Bluelog differs from most Bluetooth scanners in that it prioritizes speed of reporting over anything else (i.e. it doesn’t spend time trying to pull detailed data from a device) and doesn’t require any user intervention to function. As the name implies, its primary function is to log discovered devices to file rather than to be used interactively. Bluelog could run on a system unattended for long periods of time to collect data. In addition to basic scanning, Bluelog also has a unique feature called “Bluelog Live”, which puts results in a constantly updating Web page which you can serve with your HTTP daemon of choice.
