This app is awesome. I lost a little white Nest temperature sensor (BLE) that I keep in the attic, it fell in the middle of the attic's white insulation, I spent 1 hour digging around the insulation with no luck, I gotta hopeless... but using this app, it took me just 5 minutes to find the sensor, I just configured the app filter to show me the strong signals and I knew the sensor sends data every 10 seconds. So, I just moved my phone around looking for the right signal and its strength.

Heard of those little R2D2 droids from Disney Galaxy's Edge? They respond to BLE beacons at the park and from other droids. My son desperately wanted his to do that at home. With this app i was able to do a Bluetooth scan, copy the R2D2 broadcasting its own beacon, then play that broadcast back from my own mobile. i can leave this app running all day long with no battery drain. My son's R2D2 chatters periodically all day long. Thank you so much for this easy to use app!
