3. 打印出这个广播数据，消息内容有变化，部分消息有重复，最多看到过8次：

这是你上面三个多月前问的问题呀 答案也早就有了，我看你另外一个帖子里已经用上了

我的云麦mini2也是没有数据，已经将大佬的压缩包、on_ble_advertise都烧写进去了，还是不行

这个是logs：

请教下我的云麦mini2得到的数据是这样
后面长度是6不是14，需要怎样修改呢，谢谢

大佬，请问你的mini2连得上了吗？我的一样是这个问题

没有创意

ED.67.27.47.7F.5F是蓝牙MAC，0x20CA也不是MAC地址后两位，实在不一样，(19)后面是我看到的公斤数，转换发现5525---1595，两位对应千克数，cpp也不知道怎么修改了，还请指教。

我的云麦mini2也是没有数据，已经将大佬的压缩包、on_ble_advertise都烧写进去了，还是不行

这个是logs：

提示payload has wrong size (6)!，你得先用on_ble_advertise把体重秤广播的数据打印出来，看看到底是什么内容，然后再根据实际情况修改代码

感谢大佬，我后面回去再试试。不过我刚好这两天逆向好轻APP了，也算是解决了同步的问题
