Bluetooth is a standard and a communications protocol primarily designed for low power consumption, with a short range.
Bluetooth makes it possible for these devices to communicate with each other when they are in range. Because the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other.
How to Find, Detect Bluetooth Devices
You can manually search, find and detect all bluetooth devices near you through your computer. All bluetooth devices, which are in discoverable mode, will be searched by your computer or your bluetooth device.
However, if you want more control over this search, and also wan to monitor the activities of all bluetooth devices near you, then we recommend you to use the NirSoft’s BluetoothView.
BluetoothView is a freeware utility that runs in the background, and monitor the activity of Bluetooth devices around you. For each detected Bluetooth device, it displays the following information: Device Name, Bluetooth Address, Major Device Type, Minor Device Type, First Detection Time, Last Detection Time, and more.
BluetoothView can also notify you when a new Bluetooth device is detected, by displaying a balloon in your taskbar or by playing a small beep sound.
An interesting use of BluetoothView
If you have neighbors or family members that use a cellular phone with Bluetooth turned on then you can easily know when they come home and when they leave, by using the ‘First Detected On’ and ‘Last Detected On’ fields.
BluetoothView doesn’t require any installation process or additional DLL files. In order to start using it, simply copy the executable file (BluetoothView.exe) to any folder you like, and run it. A few seconds after you run it, BluetoothView will start to gradually display all detected Bluetooth around you.
