[hbldh]

Implement CoreBluetooth backend to use for macOS for true cross platform capabilities.

@kevincar Is the replacement of self necessary here? I get it to work without replacing it (I dislike the feeling of overwriting it...), but I want to know if you have more insight into it than me?

[kevincar]

PyObjC documentation shows an example of creating an objective-c style python class here. I simply followed the examples on that site to avoid any unexplained behavior that may have arisen.

However, I never tested the code without replacing self. So if the code works without replacement, then it sounds like we might be able to remove that.

The discovery timout in connect is pretty high: 10 seconds. Have you assigned it this high just to ensure no device is missed or have you been experiencing problems with lower threshold?

I will not argue with the official documentation's advice to rebind self. It stays as it is.

Made some minor edits during my first testing of it on a Mac mini mid 2011 running OS X 10.11.6. It works very well! Will be testing more tomorrow!

If you're referring to this then yes. I set it to 10 seconds to allow timing to find devices.

As an update: I previously was utilizing a supplemental framework to get around some issues I was having with assigning delegate objects. With these changes the framework can be removed.

Hello, sorry for leaving this hanging for some time. I have been very strapped for time available for spare time coding lately...

The changes you propose, does that remove the need for the corebleak Xcode project alltogether? The corebleak.framework as well? Or are they still needed?

Does something require any compilation at any stage? I am thinking for building binary wheels on CI system.

[kevincar]

The Xcode project was there to build the corebleak.framework via the makefile in the core bleak folder.

But to answer your question, yes, with these changes, neither the framework nor the Xcode project are necessary.

I had created this framework for assigning values to read-only properties of objective-c objects before realizing that PyObjC already provides setter functions for this purpose.

Integrated kevincar/bleak@a7fa367 into bleak and will merge to master and deploy and 0.5.0 to PyPI tomorrow (I cannot test the new changes on a Mac today, so I want to wait for that).

[hbldh]

This has now been released in version 0.5.0, which is now available from PyPI. Thank you very much. If you want to, add yourself to the CONTRIBUTORS.rst file and make a PR for that!
