How do you write cross-platform Bleak code, that uses the OS-specific scanners and options?

Hi,

I'm trying to use the pytimeflip library to interface with my Timeflip device.

My computer is running macOS.

However, it seems that macOS does BLE a bit different - the first issue I hit is that it seems macOS doesn't return normal MAC addresses by default (#284, #140).

However, I saw #1073, and it seems like I can use the macOS specific Bleak scanner, which could potentially get me MAC addresses (and I assume would work better under macOS).

My question is - what is the recommended (or best-practice) way to write Bleak code, that handles the different platform backends (e.g. Windows vs Linux vs macOS), and with specific arguments (e.g. use_bdaddr)?

Bleak automatically uses the correct backend for your OS. If this is for a personal project, then sure, use use_bdarrd if you want to, but don't count on it working for everyone since it is a hack. It would be best to just use the UUID returned as the ID on macOS instead.
