Nice. I saw someone comment about this yesterday, and today, someone built it.
Someone used Claude:
Findphone: Locate a nearby Bluetooth device by signal strength

#22Google is reportedly launching an airtag competitor tomorrow. I'm interested to see the details. I have a pair of their headphones, and they don't broadcast when the case is close, which makes them easy to loose.
Hopefully it works with GrapheneOS.

Wait, I can purchase $2-$4 "find hub" compatible beacons all day and have been for months. I have even made my own using a CR2032 + ESP32-C3 and they work fantastic with "find hub" - is this just an official version of that or something else entirely?

#24Weirdly Apple seems to have something like this built-in for finding an apple TV remote - but the same flow doesn't appear to be launchable for any other device
It works for newer AirTags as well, this isn't BLE based but Ultra Wideband. That's an entirely different technology, and if you look at it from an RF lens, a highly impressive one.
UWB is interesting.
If you use your phone as a key for your Tesla, you can turn on "nearby interactions" on the phone and the car can very accurately know your position.
Then with the accurate positioning, you can stand still in front of your trunk, and have it open. (it is a setting, hands free trunk/frunk)

#25 This is not a Geiger counter, despite sounding a little like one.
Jokes aside, I thought BLE RSSI was too noisy to be accurate enough for something like this.

#26Apple uses similar for finding individual airpods (which don't have a UWB antenna), but it's also used in conjunction with the camera to map signal strength to 3d space.
