We have the new Minew F6 Tracker Beacon in stock.
Tracker beacons are different from normal beacons in that they are designed to be connected to an app for the majority of the time. Non-tracker beacons just advertise and aren’t usually connected except for setup.
The F6 comes with iOS and Android SDKs that provide for bonding/pairing with a password, listening to events such as connecting, connected, disconnected, getting the MAC address and RSSI, ringing the tracker, receiving a button press event, receiving a notification n seconds after disconnect and disconnecting at a given distance (received signal power level, RSSI).
