async def main():
    reader = X714(name="RFID Reader", start_reading=True)
    reader.on_event = lambda name, event_type, data: (
        asyncio.create_task(on_tag_read(name, data)) 
        if event_type == "tag" else None
    )
    
    await reader.connect()
    
    while True:

Device Examples

X714 RFID Reader

from smartx_rfid.devices import X714

# Serial connection (auto-detect)
reader = X714(name="X714-Serial")

# TCP connection
reader = X714(
    name="X714-TCP", 
    connection_type="TCP", 
    ip="192.168.1.100"
)

# Bluetooth LE
reader = X714(
    name="X714-BLE", 
    connection_type="BLE"
)

def on_event(name: str, event_type: str, data: dict):
    if event_type == "tag":
        print(f"EPC: {data['epc']}, Antenna: {data['ant']}")

reader.on_event = on_event
await reader.connect()

R700 IOT Reader

from smartx_rfid.devices import R700_IOT, R700_IOT_config_example

reader = R700_IOT(
    name="R700-Reader",
    ip="192.168.1.200",
    config=R700_IOT_config_example
)

reader.on_event = on_event
await reader.connect()

Database Integration

from smartx_rfid.db import DatabaseManager
from sqlalchemy import Column, String, Float, Integer, DateTime
from sqlalchemy.orm import DeclarativeBase
from datetime import datetime

class Base(DeclarativeBase):
    pass

class TagModel(Base):
    __tablename__ = 'rfid_tags'
    
    id = Column(Integer, primary_key=True)
    epc = Column(String(50), unique=True, nullable=False)
    tid = Column(String(50))
    ant = Column(Integer)
    rssi = Column(Float)
    created_at = Column(DateTime, default=datetime.utcnow)

# Initialize database
db = DatabaseManager("sqlite:///rfid_tags.db")
db.register_models(TagModel)
db.create_tables()

# Use with sessions
with db.get_session() as session:
    tag = TagModel(epc="E200001175000001", ant=1, rssi=-45.2)
    session.add(tag)

# Raw SQL queries
results = db.execute_query_fetchall(
    "SELECT * FROM rfid_tags WHERE rssi > :threshold",
    params={"threshold": -50}
)

Supported Databases

• PostgreSQL: postgresql://user:pass@localhost/db
• MySQL: mysql+pymysql://user:pass@localhost/db
• SQLite: sqlite:///path/to/database.db

Webhook Integration

from smartx_rfid.webhook import WebhookManager

webhook = WebhookManager("https://api.example.com/rfid-events")

# Send tag data
success = await webhook.post("device_01", "tag_read", {
    "epc": "E200001175000001",
    "rssi": -45.2,
    "antenna": 1,
    "timestamp": "2026-01-15T10:30:00Z"
})

if success:
    print("Webhook sent successfully")

Tag Management

from smartx_rfid.utils import TagList

# Create thread-safe tag list
tags = TagList(unique_identifier="epc")

def on_tag(device: str, tag_data: dict):
    new_tag, tag = tags.add(tag_data, device=device)
    
    if new_tag:
        print(f"New tag: {tag['epc']}")
        # Add custom data
        tag['product_name'] = "Widget ABC"
    else:
        print(f"Existing tag: {tag['epc']}")

# Use with device events
reader.on_event = lambda name, event_type, data: (
    on_tag(name, data) if event_type == "tag" else None
)

    tags = TagList()
    
    async def process_tag(name: str, tag_data: dict):
        # Check if new tag
        new_tag, tag = tags.add(tag_data, device=name)
        
        if new_tag:
            # Save to database
            with db.get_session() as session:
                session.add(TagModel(**tag_data))
            
            # Send notification
            await webhook.post(name, "new_tag", tag_data)
            print(f"New tag processed: {tag_data['epc']}")
    
    reader.on_event = lambda n, t, d: (
        asyncio.create_task(process_tag(n, d)) if t == "tag" else None
    )

API Reference

Core Modules

• smartx_rfid.devices - Device communication classes
• smartx_rfid.db - Database management
• smartx_rfid.webhook - HTTP notification system

Event System

All devices use a consistent event callback system:

def on_event(device_name: str, event_type: str, event_data: dict):
    """
    Event types:
    - "connected": Device connected successfully
    - "disconnected": Device disconnected
    - "tag": RFID tag detected
    - "error": Error occurred
    """
    pass

device.on_event = on_event
