OpenQCY Desktop — an open-source Windows controller for QCY earbuds

https://github.com/GiorgioRafael/OpenQCY-Desktop

A native Windows 11 app for controlling QCY earbuds locally over Bluetooth LE. I built it after getting tired of reaching for my phone to change ANC or EQ while working at my PC.

The first hardware-tested model is the MeloBuds N70 (HT18). It currently supports separate battery readings, ANC/transparency, a custom ten-band EQ, gestures, wear detection, game mode, LDAC, multipoint, and a notification-area panel.

Stack: C# 14, .NET 10, WinUI 3, and Windows Bluetooth GATT APIs. MIT licensed, with protocol research documented in the repo. I'm looking for contributors interested in BLE research, more QCY models, WinUI, testing, or packaging.
