BACnet Write Property Request Not Being Sent (Verified via Wireshark)

[tjarkst]

The write_property method is not sending BACnet packets as expected. While read operations work correctly, write operations fail silently with no packets visible in Wireshark.

Reproduction Steps

import BAC0

# Initialize connection
bacnet = BAC0.lite(ip='192.168.0.97', port=port)

# Read works
read_result = bacnet.read('192.168.0.100 analogValue 459 presentValue')
print(f"Read successful: {read_result}")

# Write fails silently
write_result = bacnet.write('192.168.0.100 analogValue 459 presentValue 100 - 8')
print(f"Write attempted: {write_result}")

Try

await bacnet._write(args)

And tell me if it is better

Complément : the write method creates a asyncio task. With await _write you force the write to happen now.

It worked indeed

This is strongly related to "me learning asyncio" and trying to keep some function synchronous to be used in the REPL... I suspect at some point I'll need to clean that up. And rely on awaitable functions.
