How to find a device by bluetooth signal?

Question

Android

There is a Xaomi Mi Band2, which is lost, but is visible in the proprietary Mi Fit application, that is, the target. Is it possible to find it? By signal strength? If so, is it possible with a smartphone? Or a device that can be rented for cheap?

Answer 1

The Find Mi Band application will help you, unlike mifit, it can send a constant vibration. In addition, there is a blue tooth signal indicator.

Answer 2

Similarly, I lost my bracelet in tall grass, installed the BLE Scanner program from the market, there is a radar mode. Then I went in a circle in the direction of increasing the signal, until the signal became maximum, then I searched with my hands. Found at about 40 cm

Answer 3

In the same proprietary application, there is a button "vibrate with a bracelet." Vibrate and follow the sound.
In terms of signal strength - it is very difficult - it is only evenly distributed in a pure field.
