摘要： An association connection is established between a first Bluetooth Low Energy (BLE) device operating in central mode and attached to an asset to track, and a second BLE device operating in peripheral mode and associated with a physical location within the asset management environment. An association connection is established between the second BLE device and a third BLE device operating in central mode and coupled to one or more computer processors, and the association information stored in the second BLE device to the third BLE via one or more broadcasting frames is periodically transmitted. Based on current association information between the first BLE device and the second BLE device, an identity of the asset to which the first BLE device is attached, and the physical location of the second BLE device within the asset management environment is identified.
