First you have to limit yourself to a specific radio variant, because the actual radio hardware is different on different esp32 variants.

Then you have a massive amount of things this "blobs" actually contain.

And last there is also a lot of continues movement integrating newer radio features. E.g newer BLE version standard implementation and so forth. So you play catch with actual new development.

You really don't want to know just how bad Windows' Bluetooth stack is. It doesn't even implement basic features. I would hesitate to call it a compliant implementation at all. Oh, the API call for all BT features exist, but they either do nothing, return garbage and lies, or are just broken.

If you use a well supported BT adapter under the right Linux distro, it's flawless.

You're deflecting blame for your shitty decisions onto a racist strawman.

Buy a good Bluetooth adapter which is actively supported by the Linux kernel. Do 20 minutes of research instead of buying the cheapest thing you can and then spouting racist bullshit to post-hoc justify yourself.

If you take a few moments to think about what you're doing, you can get Bluetooth working flawlessly by simply buying the correct adapter. And you don't have to be a racist xenophobe about it.
