How does a webpage control a Bluetooth LED strip?
Most generic BLE RGB strips (like the Triones protocol) use an open GATT transparent transmission. Once connected, this page writes a binary Hex payload formatted as [0x56, R, G, B, 0x00, 0xF0, 0xAA] to characteristic 0xFFE9, directly controlling the LED duty cycle at the hardware level with zero latency.
