The Sentrius™ BT710 advertises an identifying beacon used by other nearby BT710 compatible Bluetooth tracking devices and
gateways to log proximity to the tracker. This advertisement includes information such as a user configurable device identifier,
a hardware identifier, and current status of the Bluetooth tracking device.
You can configure a tracker using a Bluetooth connection and the Laird Connectivity ‘Sentrius™ BT710 – Bluetooth Tracker

possible for a mobile app or gateway to connect to the Bluetooth tracking device for configuration of parameters and/or data log
