What is Reddit's opinion of Bluetooth 4.0 Scanner?

From 3.5 billion Reddit comments

This app can tell you signal strength. Try it out and see if it can detect the remotes signal. Might not work.

Smartphones would be best at scanning for this type of info. Here's example apps:

iOS example app: https://itunes.apple.com/us/app/bluetooth-smart-scanner/id509978131?mt=8

Android example app: https://play.google.com/store/apps/details?id=com.bluemotionlabs.bluescan&hl=en

(I have vetted neither app. They are just the first to come up in my searches.)

If the Bluetooth device is broadcasting then it should come up in these scans.

Outside of that, here's the manual I got from my Googling: http://sunrise.pgdrivestechnology.com/manuals/pgdt_bluetooth_manual_SK79614-01.pdf
