Thanks Pramod for the logs! The connection failure was caused by the same "Unknown Connection Identifier" error. However, Since Minnie uses Broadcom BCM4354, we may need to conduct more experiments before we make sure it is a firmware issue. Pramod, I will provide you with a new Minnie test image in which the supervision timeout would be lengthened from 2 seconds to 4 seconds. And let's see if this mitigate the issue.

Hi Pramod, Miao has a patch (https://chromium-review.googlesource.com/#/c/chromiumos/third_party/kernel/+/1000097/) landed on "10568.0.0" which is supposed to mitigate the issue. Could you test fitbit again with a version newer than "10568.0.0"? Thanks!

Hi Joseph, I checked on 10569.0.0 build on minnie and faced the same connection issue as in #0.

Hi Pramod, thanks for your prompt action! Would you please also capture logs so that I could double check? Thanks!

Hi Pramod, I know the reason now. The patch in C#3 is for kernel 4.4 only while Minnie uses kernel 3.14. Please wait until the patch lands on kernel 3.14. Thanks!

Hi Pramod, Miao's CL has landed to kernel 3.14 on R68-10582.0.0. Could you please help test again? Thanks very much!

Hi Pramod, thank you for the logs. The btsnoop.txt log is what I need to look at. However, its did not capture the time interval that the connection/disconnection was happening. Could you please capture the log again? Thanks!

Hi Pramod, I am sorry that I did not explain clearly. I would need the logs captured when Minnie connects and disconnects the fitbit device. In the log above, I only saw scanning data. BTW, I need both the btsnoop log and the messages log. Thanks!

Hi Joseph, On 10585.0.0 / 68.0.3397.0 build, the fitbit app doesn't detect that we have a fitbit device nearby. Even though we have the fitbit zip device on and next time to chromebook we see same error message ( refer attached screenshot) |
