If you have multiple fixed BLE receivers, you can do full trilateration. This project integrates into Home Assistant using HA proxy BLE receivers to track phones moving around in your house: https://github.com/agittins/bermuda | ||||||||

20 years ago I meant to write something like this, but so friends could find each other nearby in places like clubs. | ||||||||

I thought unless an android or iPhone is beaconing, it only broadcasts ble on device wake? Maybe I'm misremembering, but for example my esphome proxies in HA will show nothing for ages at night while my phone isn't being interacted with. If the phone is lost, it's probably not super awake lol | ||||||||

Weirdly 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 | ||||||||

Bluetooth now has something that does this more accurately on a protocol level: https://www.bluetooth.com/learn-about-bluetooth/feature-enha... | ||||||||
