Cannot write floating point values with _write()

[skygreenslade]

I cannot write floating point values with _write(). Instead "null" is being written, and no error or return value is provided.

Example which creates the issue:

async with BAC0.start(ip=_ip) as bacnet:
        result = await bacnet._write(f'{_device_ip}:{_port} analogOutput 1 presentValue 0.1 - 3')
        print(f'\nResult: {result}\n')

Output (truncated):

Result: None

I think this may be due to the regex parsing the write arguments parsing a word for the value. Is there any workaround for this?

I'm pretty sure the write function doesn't return something.

I just send this to the network

I highly suggest you to have wireshark open. Just to see what is going on on the network.

I don't have my wireshark logs from this anymore, I have since moved on from it. I was able to verify that using the script shown above correctly sends 'NULL' to the device rather than the float value.

The return value thing is more of an aside, the function documentation states that it will return something, and if the communication failed there are some exceptions that may be raised, so I wanted to rule out that first step.

you were right on the regex. Thanks
Please try the develop branch

I also added the return response to the _write fucntion, tell me if this works for you

Thanks for the update! I am currently working on other projects, but I will follow up if I am able to test out the new functionality.
