我们使用的是BCM20736芯片，带有SDK 2.2.3。
我们的固件初始化设备并开始广告。在正常操作中，该设备将继续做广告，直到永远。然而，有时我们注意到广告突然停止。这发生在大约1个10个BCM部件中（从120个设备的样品中）。当广告停止时，它可能在几分钟或几小时内发生。嗅探器没有检测到广告。 我们使用我们的代码周期性地调用BLoopReIX GETSCAN（Valk）函数，监视设备认为它的广告状态是什么。我们根据函数的返回来切换I/O线。（NOX可发现=低，可发现=高）。当问题发生时，我们从来没有看到这条线变低。这可能意味着无线电硬件不发送，尽管无线电固件状态机的状态。 删除/重新应用电源再次启动广告，但失败的单元将再次失败。大多数单位从来没有失败，即使经过几天的连续运行。 一些IC日期代码似乎显示出比其他故障更多的故障，并且一些日期代码没有显示故障。 更换失效PCB上的BCM IC会导致问题消失——问题似乎是遵循BCM集成电路，而不是硬件的其余部分。 另外两篇文章（“广告似乎是FLAKEY”和“原型板的问题与先前报道的类似”）描述了一些类似的问题。 谢谢， 杰克逊 以上来自于百度翻译 以下为原文 We are using a BCM20736 IC, with SDK 2.2.3. Our firmware initializes the device and starts advertising. In normal operation, the device will continue to advertise forever. However, sometimes we notice that advertisement stops unexpectedly. This happens in about 1 in 10 BCM parts (out of a sample of 120 devices). When advertisements stop, it can happen in a couple minutes, or a couple hours. No advertisements are detected by a sniffer. We instrumented our code to call the bleprofile_GetDiscoverable(void) function periodically, to monitor what the device thought its advertising state was. We toggle an I/O line based on the return from the function. (NO_DISCOVERABLE = LOW, DISCOVERABLE = HIGH). We never saw this line go LOW when the problem occurred. This may imply that the the radio hardware is not transmitting, despite the condition of the radio firmware state machine. Removing/reapplying power starts advertisements again, but a failing unit will fail again. Most units never fail, even after several days of continuous operation. Some IC date codes seem to show more failures than others, and some date codes show no failures. Replacing the BCM IC on a failing PCB causes the problem to disappear -- the problem seems to follow the BCM IC, not the rest of the hardware. Two other posts ("Advertisement seems to be flakey" and "Prototype boards are failing with issue similar to one previously reported") describe somewhat similar problems. Thanks, Jackson

你认为你可以拿你的失败板，并用Hello传感器应用程序加载它吗？这可能会给我们一些线索。
健康的硬件，也许布局。 以上来自于百度翻译 以下为原文 Do you think you can take of your keep-on-failing boards and load it with the hello sensor app? This may give some clues on the health of the hardware and perhaps layout. |

我们已经尝试过了（作为我们打开的案例的一部分）。我张贴在论坛上，试图得到一些社区的反馈。 该测试的结果似乎表明，HeloLoor传感器应用程序不会失败。 但是，问题的最困难部分是一些ICS总是失败，而另一些则根本不会失败，即使加载相同的代码，并且运行数天。所以，我不相信失败只是与代码有关。代码和硬件之间的关系似乎是间歇性地弹出的。 我特别感兴趣的是在“广告似乎是FLAKEY”的帖子中，这个问题被追踪到一个错误的标签。海报取代了标签，问题没有再次出现。 以上来自于百度翻译 以下为原文 We have tried that (as part of a Case we have opened). I posted on the Forum to try to get some community feedback as well. The result of that test seems to show that the hello_sensor application does not fail. But, the most difficult part of the problem is that some ICs fail consistently, while others do not fail at all, even when loaded with the same code, and run for several days. So, I don't believe the failure is only related to the code. There seems to be some relationship between the code and the hardware which is popping up intermittently. I was especially intrigued by the observation in the "Advertisement seems to be flakey" post that the problem was traced to a faulty Tag. The poster replaced the Tag and the problem did not reappear. |

珠海易胜 发表于 2018-11-6 09:22 你的意思是说，在那些坏的板/部件上，Hello传感器应用程序没有失败？ 如果你有预感，IC可能是这里的问题，那么请与正在查看你的情况的工程师讨论这个问题。对于这种情况，我们通常需要做一个FA。 以上来自于百度翻译 以下为原文 You meant to say that on those bad boards/parts, the hello sensor app did not fail? If you have a hunch that the IC could be the issue here, then please discuss this with the engineer who is looking into your case. We usually may need to do a FA for such cases. |
