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
