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()
