Python 3 Compatibility

[3DCoded]

I am using MacOS 11.1 and Python 3.9.1 64-bit. When I try to import WonderPy, I get an error:

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import WonderPy
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/WonderPy/__init__.py", line 1, in <module>
    from . import core        # noqa
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/WonderPy/core/__init__.py", line 1, in <module>
    from wwCommands  import WWCommands  # noqa
ModuleNotFoundError: No module named 'wwCommands'

Is there a way to use this package in Python 3?

I got the same WWCommands error on Python 3 with MacOS 11.1

I get this error on Python 2.7 - how did you get past it? @smattar2020

I think I enabled Bluetooth for Python or whatever Code IDE you may be using. I think the Dash/Dot/Cue has to be on when you import it.

[kevincowan]

That didn't help @smattar2020 I'd really love to know how you got this to work on Python 2.7 on MacOS 11.1 - thanks!

[3DCoded]

I did it a while ago and am not sure I remember how to do it. This issue is for making it work on Python3, not Python 2.

[3DCoded]

You may have to install CoreBluetooth somehow

[3DCoded]

eg. at https://pypi.org/project/pyobjc-framework-CoreBluetooth/

[kevincowan]

I tried that and it didn't work

I know you are trying to get Python3 working - I can't make it work on Python 2.7 on 11.1

[3DCoded]

I have uninstalled Python 2 recently because it was deprecated since December 2020 and because it was crashing my Mac. I think if you are trying to get it to work on Python 2 on macOS Big Sur, you should open your own issue for that.

[kevincowan]

Agreed - thanks for your help. We really need it work on Python 3

[kevincowan]

I've emailed their support to ask about Python 3 support - we need this

I ported some work by the github community to use bleak backend instead of pygatt, and I have tested on my mac m1 and windows machine for anyone still looking.

@mewmix You are a hero! Can't wait to try this!

Thanks

I created a more direct port with additional functionality that's also cross platform:
