Мне нужна помощь в настройке BAC0 для взаимодействия в качестве устройства. ⇐ Python

[Anonymous]

У меня есть пример кода BAC0, но он генерирует ошибку, сообщающую что-то о датаграмме IPv4. Я прочитал документацию и файлы справки библиотеки, и, похоже, часть этого работает, прежде чем произойдет сбой.

#!/usr/bin/env python3
import asyncio
from BAC0 import connect
from BAC0.core.devices.local.factory import analog_input

def defining_objects(device):
from BAC0.core.devices.local.factory import ObjectFactory
ObjectFactory.clear_objects()

analog_input(
instance=10,
name="Frequency",
properties={"units": "hertz"},
description="Frequency",
presentValue=18.0,
relinquish_default=21,
)
return device

async def main():
try:
# Connect to BAC0 device
#device1 = connect(ip="192.168.13.193/24", port="47808", deviceId="1110")
device1 = connect(ip="192.168.13.193/24")

defining_objects(device1)

while True:
device1["Frequency"].presentValue = 42.0  # Test value
print("Device 1 Frequency:", device1["Frequency"].presentValue)
await asyncio.sleep(2)
except Exception as e:
print(f"An error occurred: {e}")

if __name__ == "__main__":
asyncio.run(main())

Я не знаю, смогу ли я вообще использовать свою Wi-Fi-карту в качестве сервера bacnet с BAC0. Мне просто нужна помощь о том, как правильно настроить BAC0 для сообщения значения, которое я могу использовать YABE для мониторинга по сети.
