The Ketai lib can’t handle fast incoming data, so I wrote a Bluetooth code that does.  
I posted that code [here](https://discourse.processing.org/t/android-bluetooth/27140/14) and added also the code you requested as an example for others as well.  
I kept your design, because I think it’s nice, but re-wrote the code as a class to easily construct multiple knobs if needed. Don’t forget to give the needed permissions.
