1 Reason: could not connected
如果测试遇到该问题，麻烦贴一下上面的截图，并且请帮忙指出上图红色框里面对应的信息：
1.Found by EID at xxxxxx， xxxxx对应的地址是什么
2.手机端显示connecting对应的时间点
3.手机端显示Test finished对应的时间点

log分析：
截图位置1：
"Found by AK at 48:48:6A:60:5A:F7"
截图位置2：
"Scaning by EID"
"Found by EID at 7B:F8:BE:9E:64:E0"
截图位置3：
手机尝试connecting 7B:F8:BE:9E:64:E0
但是此时耳机端因为 48:48:6A:60:5A:F7 这条link还没有断掉
手机再尝试连7B:F8:BE:9E:64:E0的时候
耳机端会认为link已经存在，直接拒绝这次连线
导致手机端测试显示 "Could not connect"
这个问题不是必现的

想请问是不是可以先断开48:48:6A:60:5A:F7这条link，确保手机和耳机的link断开之后, 再尝试执行截图位置2以及之后的操作？
不然的话，
如果在48:48:6A:60:5A:F7这条link 断开之后， 再scan 到7B:F8:BE:9E:64:E0 并且尝试创建BLE link 是没有问题的。
如果在48:48:6A:60:5A:F7这条link 尚未断开之前 ，就scan 到7B:F8:BE:9E:64:E0 并且尝试创建BLE link， 就会遇到上面描述的问题。

这个问题需要咨询google：
from google:
Thanks for reporting. I found a race condition which can lead to this result. I'll prepare a fix, but since it does not reproduce on devices that we have, and to save some time, I would like to share an APK with the fix with you to verify it resolves the issue.
Can you provide a Google account on which I can share the APK once it is ready?
google 提供的新的apk: validator_realtek_diag.apk
Alice Zhou(周丽) 麻烦用这个apk压测试试看，是否还能复现到这个问题
