  • Middleware Module
    The middleware module provides resident service to query deployed readers
    to get the communication packet from tag. The communication packet
    contains tag_ID, reader_ID, exciter_ID, RSSI, emergent button pushed,
    battery life, etc. The middleware can disassemble the communication packet
    send from tag and save to database. If the deployment information changed,
