你好。
我注意到当使用BVLINK或MEMS软件与iPhone配对的设备时，BlueCoin使用大约40-45mA。这似乎很高。基于我过去用于类似用例的其他类似产品，我期待最大10-20mA。此外，如果iPhone应用程序中报告的动力电池电量是准确的（我怀疑自完全充电后它会另外报告97％和80％充电），那么当LiPo容量为20-30％时，设备似乎会关闭。即使设备没有“做任何事情” - 即仅仅与电话配对，该功率使用也是相同的。 因此，我有以下问题： 1）这听起来合理/正确吗？ 2）是否可以关闭所有其他功能以节省电量？ 3）我可以激活超低功耗待机模式吗？我如何唤醒设备？ 4）我可以采取哪些其他节电措施？ 5）充满电后，为什么电池电量在80％到97％之间切换？ 目前我唯一的解决方案是每次要使用麦克风时都要严格关闭设备并重新启动。 具体来说，我的用例是按一个按钮记录一些语音，然后释放按钮停止记录。电池需要至少持续一周。我的空间要求允许LiPo高达500mAh。 我已经阅读了STEVAL-BCNKT01V1 - BlueCoin Starter kit - STMicroelectronics提供的文档，但它们还不够。任何与实际编程BlueCoin更相关的内容都会感激不尽，因为我对这种特殊类型的设备非常陌生（我直到现在才编写Arduinos）。 非常感谢， PartRobot #bvlink＃battery-life #power #bluecoin 以上来自于谷歌翻译 以下为原文 Hi. I'm noticing that when using the BVLINK or MEMS software with the device paired with an iPhone the BlueCoin is using about 40-45mA. This seems a high. I'm expecting 10-20mA maximum based on other similar products I've used in the past for similar use cases. Additionally, if the power battery levels reported in the iPhone app are accurate (which I doubt since at full charge it reports alternately 97% and 80% charged), then the device appears to shutdown when the LiPo is at 20-30% capacity. This power usage is the same even if the device isn't 'doing anything' - i.e. is merely paired with the phone. Consequently I have the following questions: 1) Does this sound reasonable/correct? 2) Is it possible to shut down all other features to conserve power? 3) Is there an ultra-low power standby mode I can activate? How do I then wake the device? 4) What other power saving measures can I take? 5) Why does the battery level switch between 80% and 97% when fully charged? Currently my only solution is to hard shut down the device and start it up again every time I wish to use the microphones. Specifically my use case is to press a button to record some speech and the release the button to stop recording. The battery needs to last at least a week. My space requirements allow for a LiPo up to 500mAh. I have read the docs available at STEVAL-BCNKT01V1 - BlueCoin Starter kit - STMicroelectronics but they are insufficient. Anything more related to actually programming the BlueCoin would be gratefully received as I'm very new to this particular type of device (I've only programmed Arduinos until now). Many thanks, PartRobot #bvlink #battery-life #power #bluecoin

谢谢，但我的意思是支持与我的问题相关的文档。我已经阅读了所有这些内容，但我没有看到上述解决方案的参考。但是，我必须补充一点，我不一定了解我正在读的所有东西！
以上来自于谷歌翻译 以下为原文 Thanks but I mean supporting documentation related to the questions I have. I've read through all that and I don't see a reference to solutions for the above. I must add, however, that I don't necessarily understand all what I'm reading! |

这可能会更好地转移到
https://community.st.com/community/mems-sensors-community/mems-sensors-forum 需要更好地接触负责BlueCoin套件设计的FAE和管理人员。 通常的动态是通过您当地的ST销售和支持联系人，尽管我认为通过“社交媒体”或论坛类型的场所转移到更多员工可用和响应的期望。你将这些东西推到了车库/地下室工作的制造商和工程师的手中，而不仅仅是Apple / Nike等大型设计团队，他们拥有深厚的人才。 Kling.Brian.001 “ 注意：原始帖子包含大量线程对话，只能迁移到第9级 以上来自于谷歌翻译 以下为原文 This might be better moved to the https://community.st.com/community/mems-sensors-community/mems-sensors-forum There needs to be better access to FAE and managers from the group responsible for the BlueCoin kit design. The usual dynamic for that would be via your local ST sales and support contacts, although the expectations I think are shifting to more staff being available and responsive via 'social-media' or forum type venues. You're pushing these things into the hands of makers and engineers working out of garages/basements, not just large design groups at Apple/Nike etc with deep rosters of talent.

谢谢克莱夫。是的，这似乎是一个发布此更好的地方。我现在就这样做。
正如你所指出的那样，我发现它有点不透明。幸运的是，代码在很大程度上是不言自明的，但硬件/ HAL的内容非常稀少，并且支离破碎。大多数情况下，我通过查看源代码并最终在随机论坛上解决问题，但这并不容易 以上来自于谷歌翻译 以下为原文 Thanks Clive. Yes, that looks to be a better place to post this. I'll do that now. I am finding it all bit opaque, as you point out. Fortunately the code is largely self-explanatory, but the hardware/HAL stuff is very sparsely documented and fragmented. Mostly I've figured things out by looking at the source code and ending up on random forums but it's not been easy |

克莱夫一写道：
你将这些东西推到了车库/地下室工作的制造商和工程师的手中，而不仅仅是Apple / Nike等大型设计团队，他们拥有深厚的人才。 确实。 此外，新近重新推出的“合作伙伴”计划现在不包括小型咨询公司 - 正是这类企业转向专业支持的那种人......

嗯，这肯定是一个反直觉的举动，一方面你已经进入制造商领域，以及更敏捷的小团队或创业集中思维模式的工程，反对大型缓慢移动的企业方向，小是无关紧要和无聊的，你只想打赌肯定的事情。
屏蔽和DISCO / NUCLEO板的轻松集成和混搭意味着人们会尝试更多不同的东西，成本更低，更有可能将墙上的油漆扔到墙上，看看有什么粘贴，丢弃不良解决方案，或者供应商似乎只是脱离了。 当你将成千上万的低成本电路板投入市场时，你需要提升你的支持人员来承担新的负载，以及人们习惯于接受或期望得到的响应水平，无论他们感知到的大小或业务渗透。论坛提供杠杆，你回答一个人的问题，你的答案达到100或1000在同一问题空间工作。 在一天结束时，这将由像你自己这样的个人以及那些可以快速降伞解决问题的人来进行，而不是那些充满了几乎一无所知的人，或者像他们一样浅薄的大型车身店。脚本。 以上来自于谷歌翻译 以下为原文 Well that certainly seems to be a counter-intuitive move, on the one hand you've got a push into the maker space, and to the more agile engineering of small groups or startup focused mindsets, against large slow moving corporate orientation, where small is irrelevant and tiresome, and you only want to bet on sure-things. The easy integration and mash-up of shields and DISCO/NUCLEO boards mean people are going to try more and different things, there's less cost and more likelihood of throwing paint against a wall to see what sticks, and discarding bad solutions, or ones where the vendor just seems disengaged. When you throw tens of thousands of low cost boards into the market you're going to need ramp your support staffing to carry that new loading, and the level of responsiveness people are accustomed too receiving, or expecting too receive, regardless of their perceived size or business penetration. Forums provide leverage, you answer one persons question, and your answer reaches a 100 or 1000 working in the same problem space. At the end of the day this is going to be carried by individuals, like yourself, and those that can quickly parachute into to solve problems, rather than large body-shops filled with people who know next to nothing, or is as shallow as their script. |

我已将此帖移至MEM和传感器，因此我将删除另一个。我将在内部强调这一点，看看我们是否能够对它进行一些关注！

有没有人对此有任何想法？问题仍然存在，Bluecoin无法用于此项目，直到我们了解有关低功耗模式的一些细节。
以上来自于谷歌翻译 以下为原文 Anyone have any thoughts on this? Issue still remains and Bluecoin is unusable for this project until we have some details about the low power mode. |

嗨，
我会尝试按顺序回复。 1）这听起来合理/正确吗？ 您提到的两个固件示例（BVLINK和ALLMEMS）都没有针对低功耗进行优化，并且无论固件在做什么，MPU始终以全速运行。这就是为什么你总能看到40-45mA。 2）是否可以关闭所有其他功能以节省电量？ 是的，即使STM32F446它不是超低功耗应用的最佳选择（STM32L系列将是最佳选择）。 这里有一个关于“使用具有最佳动态效率的STM32F4 MCU功耗模式”的应用笔记。 http://www.st.com/resource/en/application_note/dm00096220.pdf 即使它不是特定于STM32446，我认为它可能是一个很好的起点.3）是否有超低功耗待机模式我可以激活？我如何唤醒设备？ 4）我可以采取哪些其他节电措施？在STM32F446参考手册的第5.3.3章中 http://www.st.com/resource/en/reference_manual/dm00135183.pdf 您可以找到有关不同电源模式的详细信息。 例如，可以使用来自其中一个传感器（如加速度计）或按钮的中断唤醒设备.5）为什么完全充电后电池电量在80％到97％之间切换？ 目前还不确定。这应该进一步调查。 以上来自于谷歌翻译 以下为原文 Hi, I’ll try to reply in order. 1) Does this sound reasonable/correct? Both firmware examples you mentioned (BVLINK and ALLMEMS) are not optimized for Low Power and the MPU is always running at full speed, no matter what the firmware is doing. This is why you always see 40-45mA. 2) Is it possible to shut down all other features to conserve power? Yes it is, even though STM32F446 it’s not the best choice for very low power applications (STM32L family would be the best choice). Here there is an application note about “Using STM32F4 MCU power modes with best dynamic efficiencyâ€�. http://www.st.com/resource/en/application_note/dm00096220.pdf Even if it isn’t specific for the STM32446 I think it could be a good starting point.3) Is there an ultra-low power standby mode I can activate? How do I then wake the device? 4) What other power saving measures can I take?At chapter 5.3.3 of STM32F446 Ref Manual http://www.st.com/resource/en/reference_manual/dm00135183.pdf you can find the details about the different power modes. As an example, the device could be woken up using an interrupt coming from one of the sensors (like the accelerometer) or a button.5) Why does the battery level switch between 80% and 97% when fully charged? Not sure at this point. This should be investigated further. |

这很完美，非常感谢！非常清楚。
所以我是否正确理解我不需要考虑单个组件，我所要做的就是设置正确的中断，整个设备将睡眠/唤醒/停止？如果是这样，那真是太棒了。 另外，谢谢你指点我的手册 - 这非常有用 以上来自于谷歌翻译 以下为原文 That's perfect, thank you very much! Very clear. So do I understand correctly that I don't need to consider the individual components and all I have to do is set the right interrupt and the whole device will sleep/wake/stop? If so, that's fantastic. Also, thank you for pointing me to the manual - that's very useful |
