Bleak Lib (bluetooth) not working

Hi, I am trying to connect to a bluetooth device by running a python script via AppDaemon.

However, I get the following stacktrace when using the bleak library:

FileNotFoundError: [Errno 2] No such File or directory

Not sure how to fix this. Any ideas?

I am using v0.9.3 of the AppDaemon AddOn, and running Home Assistant 2022.8.6 on a RPi 4.

Using ssh to connect to Home Assistant, I already checked that bluetooth works via bluetoothctl.

It seems like the only thing in your code causing this is initiating a scan. It kind of looks like an issue with the module, maybe it’s not compatible with Python 3.10? Anyhow, it doesn’t appear this is an AD issue.

That could be it. Is it possible to downgrade the python version for the AppDeamon Addon?

I don’t think so but you can easily build your own docker container for AD.
