BACO Write Observation

[tugrulgucluoutlook]

Hi everyone

I`m testing BAC0 write property like below .
And it appears only internal write (_write) produces a write property confirmed request and simple-ack on the network which is captured by wireshark.

For some reason synchronous write is not working. And with the asynchronous alternative return value is always None.

Is there a work around this ?

version information in infos.py is version = "2025.06.10"

```

import asyncio
import BAC0

async def both_write_methods():
async with BAC0.lite(ip='192.168.54.160', port=47808) as bacnet:
await asyncio.sleep(1)

    # Read current value
    current = await bacnet.read('192.168.54.170:47808 analogOutput 10 presentValue')
    print(f"Current value: {current}")

    # Test 1: Try public write() method
    print("\n1. Testing public write() method...")
    result1 = bacnet.write('192.168.54.170:47808 analogOutput 10 presentValue 44.0 - 8')
    print(f"Public write result: {result1}")

    await asyncio.sleep(2)
    read1 = await bacnet.read('192.168.54.170:47808 analogOutput 10 presentValue')
    print(f"Value after public write: {read1}")

    # Test 2: Try internal _write() method
    print("\n2. Testing internal _write() method...")
    result2 = await bacnet._write('192.168.54.170:47808 analogOutput 10 presentValue 45.0 - 8')
    print(f"Internal _write result: {result2}")

    await asyncio.sleep(2)
    read2 = await bacnet.read('192.168.54.170:47808 analogOutput 10 presentValue')
    print(f"Value after internal _write: {read2}")

    # Summary
    print(f"\nSummary:")
    print(f"Started with: {current}")
    print(f"After public write: {read1}")
    print(f"After internal _write: {read2}")

asyncio.run(both_write_methods())

a93cb91 (dev branch) should fix bacnet.write(args)
