requirements: apt-get install fping
The great thing about this Bluetooth detection method is that it does not require the target device to be paired, to get a target devices mac address simply put it in discoverable mode and run: hcitool scan
Once you have the mac address, as long as Bluetooth is turned on, on the device you can ping it (again you do not need to pair the device and it only need to be in discoverable mode to initially get it's mac address) making it highly ideal for reliable presence detection.
