Architecture

File	Role
BluetoothService.cs	BLE GATT connection, scanning, characteristic management
RcspProtocol.cs	RCSP packet encoding (ANC, EQ, Gaming Mode, Key Mapping, hardware queries)
MainWindow.xaml.cs	UI state, EQ canvas rendering, button remapping grid
App.xaml.cs	Global unhandled exception handlers

Protocol

The SA-HP P10 communicates over BLE GATT using a proprietary RCSP framing:

FE DC BA [flags] [opcode] [len_hi] [len_lo] [sn] [payload...] EF

• Write characteristic: UUID contains ae01 or 0001
• Notify characteristic: UUID contains ae02 or 0002
• Battery: Standard BLE Battery Service — UUID 0x180F, Characteristic 0x2A19
