Questions about using BAC0

[raymondman111]

Hi all,

I am testing the BAC0 and represent 20 devices as the virtual devices in the network in a Linux system running on NXP's iMX8MM. Below are the questions.

1. There are ~50 objects build in the devices. The time taken to build the point list for each device is ~10s, which is quite long. Since I am using the python version 3.10, is it beneficial to use python 3.12 or above, as they are asyncio based, to shorten this duration?

2. the thread of my software running the bacnet-related part will hang up after several hours, while other threads of the same software are normal. If only 3~4 devices in the network, it can run longer without any problem. If more than 10 devices in the network, the software may hang up after an hour. At that time, there is still sufficient RAM available. Does anyone experience the same problem?

3. I want to remove the corresponding virtual device from the bacnet network when the device is powered off. But I fail to do so with unregister_device(). Can anyone advise the correct procedure?

Thanks in advance!

Are you willing to test the new flavour of BAC0 now relying of bacpypes3 and asyncio ? This would be the best choice I think. No more threads and more stable.

I can help you with the conversion if required

Dear Christian, Thanks for your reply. I have updated to python3.12, bacpypes3 and BAC0. Unfortunately, the main thread running the bacnet still gets stuck and stops responding. Not sure if I need to do some conversions of the code as mentioned in your previous email. Do you have any advice? Thanks in advance. Best regards, Raymond

Are you willing to share your code ?

[raymondman111]

Dear Christian, I will share the code with you soon. Meanwhile, I found that I didn't run the async branch of BAC0 before and so kept using bacpypes previously. After switching to the async branch of BAC0, I encountered the following error. [image: image.png] Do you have any suggestions? Thanks and regards, Raymond

There is no image in the message....

but be sure to use

python -m asyncio

to start the REPL and start playing with it. This way, there will be an event loop active

[raymondman111]

Sorry that I am not aware the image hasn't been attached. Below is the error message. Traceback (most recent call last): File "/root/bacnet/bacnet_main.py", line 19, in <module> from EcoHVAC import EcoHVAC File "/root/bacnet/EcoHVAC.py", line 4, in <module> from BAC0.core.devices.local.models import ( File "/usr/local/lib/python3.12/site-packages/BAC0/__init__.py", line 27, in <module> from .core.devices.Device import DeviceLoad as load File "/usr/local/lib/python3.12/site-packages/BAC0/core/devices/Device.py", line 88, in <module> class Device(SQLMixin): File "/usr/local/lib/python3.12/site-packages/BAC0/core/devices/Device.py", line 228, in Device def df(self, list_of_points: List[str], force_read: bool = True) -> pd.DataFrame: ^^ NameError: name 'pd' is not defined.

Type "help", "copyright", "credits" or "license" for more information.

Could you please give me any clues? Thanks and regards, Raymond

My mistake, the error is gone after installing pandas

[raymondman111]

I try to run manual_test_create_device.py under the tests folder but it gives out errors in the log file. Do you have any advice?
test_create_device.log
