[Android Central Question]

Hi,

I have some past experience working with Bluetooth on Android, where we had to support a wide range of devices, including some that were very old. It was a nightmare, and the only hope we had of getting anything to work consistently was to use SweetBlue.

At the time, I remember researching some of the issues I was seeing. My understanding was that different manufacturers were free to implement their own Bluetooth stack, and that was the source of much inconsistency across devices. I believe I also saw something that said that Google had decided to take full ownership of the Bluetooth stack to help address the inconsistencies of Bluetooth across different Android devices. However, now I can't find any evidence for that.

So my questions are:

1. Does Google now "fully own" the Bluetooth stack?
2. If so, from which Android version?
3. If not, is SweetBlue still the best option for using Bluetooth on Android?

Thanks
