Detecting proximity of a paired bluetooth device on your MAC

Lately, my Apple magic mouse went missing. After a quick research, I found a command that helped me check the signal strength of the bluetooth device. All I had to do was to initiate the command and start walking around to check for the location having the strongest signal strength.

Below is the command,

$ while x=1; do system_profiler SPBluetoothDataType | grep RSSI; sleep 0.5; done

If you have multiple devices connected, the output could be confusing. So, one device at a time!
