impinj-iot 0.4.0

Python driver for Impinj R700 RAIN RFID readers using IoT Device Interface (REST API)

impinj-iot

Python driver for Impinj R700 RAIN RFID readers using the IoT Device Interface (REST API).

Features

• Connect to Impinj R700 readers over HTTPS
• Start/stop inventory with configurable antenna ports, TX power, and RF modes
• Real-time tag streaming via NDJSON with callback-based notifications
• Query reader info (model, firmware, region, antenna count, power limits)
• Full RF mode enumeration with modulation details
• Authentication support (default: root / impinj)

Installation

pip install impinj-iot

Quick Start

from impinj_iot import ImpinjIot, ImpinjIotTagReport

reader = ImpinjIot()

def on_tag(report: ImpinjIotTagReport):
    print(f"EPC: {report.epc}  RSSI: {report.peak_rssi_cdbm / 100:.1f} dBm")

reader.set_notification_callback(on_tag)
reader.connect("192.168.1.100")
reader.set_tx_power(30.0)  # dBm
reader.start()

# ... tags arrive via callback ...

reader.stop()
reader.disconnect()
