BAC0 not working for whois, but BACpypes3 is

[jerrys987]

Hi,
I am new to BAC0 and am trying to get it to work for a simple case first. I have two bacnet/IP thermostats running. When I run bacpypes3, the whois works fine.

python3 -m bacpypes3 --address 172.18.1.29/24
> whois
2003 172.18.1.211
100001 172.18.1.210

When I try the same in BAC0, wireshark shows the who-is go out and the 2 i-ams come back 20ms later, but BAC0 does not seem to recognize them. Any thoughts what is going on?
thanks,
jerry

code:

import asyncio
import BAC0
import logging
import pandas as pd
import time

async def main():
    BAC0.log_level(stdout=logging.DEBUG)
    bacnet = BAC0.start(ip='172.18.1.29/24')
    await bacnet.who_is()
    time.sleep(2)
    await bacnet.devices
    print(bacnet.discoveredDevices)


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

sorry that the code indenting got lost. This is python 3.12.3 on ubuntu 24..04.

First thing I would try is getting rid of the time.sleep. It's a synchronous call and stop everything, Use asyncio.sleep instead

import asyncio
import BAC0
import logging
import pandas as pd
import time

async def main():
    BAC0.log_level(stdout=logging.DEBUG)
    bacnet = BAC0.start(ip='172.18.1.29/24')
    await bacnet.who_is()
    await asyncio.sleep(2)
    await bacnet.devices
    print(bacnet.discoveredDevices)


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

That wasn't the problem.
I am looking at core/functions/Alias and core/functions/Discover and I am not getting the info messages from those routines. Is there something else I need to do to get those messages besides BAC0.log_level(stdout=logging.DEBUG) ?
