How to run Bleak example on Ubuntu?

[ASabovic]

Hi guys,

Is it possible to run on Ubuntu the same Bleak example that I was running on Windows? I installed BlueZ on Ubuntu but when I tried the example, the bleak is not found. How to fix this issue?

This is not a problem with Bleak, but it seems to be a problem of mixing up Python 3.6 packages and a Python 3.8 interpreter. I think it's better to remove all these packages the way you installed them, and try again, but make sure to run pip as python3.8 -m pip then so you don't mix up versions again.

I tried that. First I uninstalled everything and installed based on the command that you provided but still same error:

Task was destroyed but it is pending!

Can the problem be related to the BlueZ version that I installed?

Don't use loop.run_forever() use asyncio.run(main()). It will automatically handle the pending tasks.

What else can I use then? I need to keep my PC available all time as sometimes the Arduino will turn off BLE and turn it on when needs to send some data.
