JHX_OTA

• 多设备升级改为逐台排队：全选 / 多选 / 单选 / 自动纳入均可；设备过多时先升一部分，其余候补，避免把手机和从机拖死 • 自动扫描新设备，本固件已成功的会跳过 • 识别到设备后才展示对应固件；普通用户看不到全部固件包 • 升级记录默认折叠，超过 20 条自动收起，可按条展开详情 • 扫描更精准，减少无关设备；升级失败可在升级页开启拯救模式 • 支持蓝牙与 Wi‑Fi 升级；预留云端固件下载 Smarter batch OTA: one device at a time, with select-all / multi / single / auto-queue. Extra devices wait in line so the phone and lamps stay stable • Newly found devices can be added automatically; already-successful firmware is skipped • Matching firmware appears only after a device is recognized • History is collapsed by default (auto-fold after 20 items); tap a row for details • Tighter Bluetooth scan; Rescue Mode on the upgrade page if an update fails • Bluetooth and Wi‑Fi upgrade; cloud firmware download is prepared
