XT1520 Product Manual 1. FUNCTIONAL DESCRIPTION 1.1. OVERVIEW The XT1520 series are Bluetooth beacons with a single chip Bluetooth 5 + ARM. The beacons allow the user to quickly identify a cart's location if it is within proximity of an XT49xx to determine whether a cart is at a distribution center or en route. Each device broadcasts a UID frame payload with a MAC address to an XT49xx at a 1 Hz frequency. This frequency, along with the namespace, are only configurable at the factory.
XT1520 Product Manual 2. GENERAL OPERATION The XT1520 attaches to Amazon carts and is used in conjunction with an XT49xx mounted on an Amazon trailer. The XT49xx periodically captures the unique device IDs at a configurable rate of all beacons in range. The XT49xx then sends the information over the cellular network, which is received by AWS.
XT1520 Product Manual 3. INSTALLATION The XT1520 offers two different means of mounting: zip ties, or 3M VHB tape. The back of the device casing is flat so the VHB tape can be adhered. The holes zip ties are indicated below.
XT1520 Product Manual 4. BLUETOOTH (BLE) The XT1520 uses Bluetooth 5 network, utilizing the Eddystone(TM) message protocol from Google.
