zebra-llrp 0.6.0

Python driver for Zebra FX series RAIN RFID readers via LLRP

zebra-llrp

Python driver for Zebra FX series RAIN RFID readers via LLRP protocol (sllurp).

Features

• Connect to Zebra FX9600 (and compatible) readers via LLRP (TCP 5084)
• Start/stop inventory with configurable antenna ports, TX power, RF mode, and session
• Real-time tag streaming with callback-based notifications
• Query reader capabilities (model, firmware, antenna count, TX power range, RF modes)
• EPC decoding with double-encoding detection (FX9600 quirk)
• TX power control by index or dBm

Installation

pip install zebra-llrp

Quick Start

from zebra_llrp import ZebraLlrp, ZebraLlrpTagReport

reader = ZebraLlrp()

def on_tag(report: ZebraLlrpTagReport):
    print(f"EPC: {report.epc}  RSSI: {report.peak_rssi_dbm} dBm")

reader.set_notification_callback(on_tag)
reader.connect("192.168.1.100")
reader.set_tx_power_dbm(25.0)
reader.set_rf_mode(1)
reader.start()

# ... tags arrive via callback ...

reader.stop()
reader.disconnect()
