Also built a desktop app for toggling ANC on my bluetooth headphones, the only ways to toggle ANC were a mobile app (which requires pairing to phone, thereby dropping connection to PC), or holding a physical button (which was next to the button to enter pairing mode so I kept accidentally pressing it), so I learned how to snoop on bluetooth LE and reverse engineered it with Android and Wireshark, it was a fun project and incredibly useful to me.
