chainway-serial
Unofficial asynchronous Python library to interact with Chainway UR4 fixed UHF RFID readers over RS-232 and TCP, built on serialx. Requires Python >= 3.14.
Unofficial and reverse-engineered: not endorsed by Chainway, and it may break without notice whenever Chainway changes their firmware.
The library has been tested with a UR4 running UHF module firmware 7.40.1 over RS-232 and TCP.
Install
uv add chainway-serial
Documentation

Usage
import asyncio
from chainway_serial import ChainwayClient
async def main() -> None:
async with ChainwayClient("/dev/ttyUSB0") as client:
print(await client.get_version())
async for tag in client.inventory():
print(tag.epc.hex(), tag.rssi)
asyncio.run(main())
ChainwayClient takes any serialx URL: a serial device path, or socket://host:8888 for a reader on the network.
Development
See CONTRIBUTING.md for setup, the gate and the live hardware tests.
