Get Bluetooth Pinger old version APK for Android
Bluetooth Pinger determines: who is near.
This application determines the availability of bluetooth-enabled devices. Each unit is owned by a single person, so if this person is there, it can detect the presence on bluetooth. You can check for the presence of people in a crowd or in a disco on their bluetooth-enabled devices, which they took with them.
App does not require that the phone and bluetooth-devices were paired. If the phone to be added to the list is not near you, you can enter its MAC-address manually.
You can contact with developer for features request.
