ACTIVE BLUETOOTH LE TAG SCANNING AND TRACKING FOR USE IN VEHICLE TELEMATICS APPLICATIONS

摘要

Bluetooth low energy (BLE) tags and a BLE tag reader with memory track and report assets located in or on a vehicle. A BLE tag is associated with each asset and has a unique ID and received signal strength indicator (RSSI). The reader and its software cooperate to scan and read the ID and RSSI from each tag located within range without pairing with the tag, date and time stamp each ID and RSSI, store a list of IDs and RSSIs of read tags and associated data in the memory, remove IDs and RSSIs from the memory if tags are not within range, to continuously update the current status of assets, and transmit the stored list by way of the modem at predetermined times to a remote server. The remote server has a database and software that stores the transmitted list of tags and associated data in the database, and generates reports for display by an end user.
