  "description_en": "QCYbutMOD is an Android client built from reverse engineering of the BLE GATT commands used by QCY earbuds with Wuqi WQ7033 and WQ7034 chips. It reads separate earbud and case battery values from characteristic 0008, sends a command to mute firmware voice prompts, and reads back gesture mappings. Device test notes record command acknowledgments and unanswered multipoint queries.",
