When you create a "New unit" from the Asset management section, you can immediately link it to one of your BLE devices, right from the creation window.
Linking a BLE device to a unit will allow you to use this unit in multiple of our solutions like Online Map, Alerts, Reports and more!
🔔 You can only link BLE devices to units that were created from Asset management, using the type "New unit".
🔔 Mobile tracking and stationary units can not be connected to a BLE device.
