Question

我最近购买了这个：http://redbearlab.com/bleshield/

我已将它连接到我的Arduino，我试图运行他们告诉我运行的第一个测试程序，这是BLE控制器草图。我已连接它并解决了我最初获得的一些原始编译错误，现在它将上传。当我上传它时，我的iPhone对盾牌没有反应。我试图弄清楚代码中是否存在问题，或者它是否与屏蔽本身有关。如果是代码，我该如何修复代码？我对Arduino来说相对较新，而且非常适合使用蓝牙。这是指南告诉我从Github下载的整个草图。

Answer 1

在过去的8个月里，我一直在努力解决这些问题，所以我会尽力帮助。我没有评论的声誉，并要求澄清具体的事情，所以我只是试图涵盖我能做的一切。

让我们先介绍一些事情：

因为您的草图已上传我假设您已将所有必需的库添加到Arduino。如果你还没有，我不知道为什么要上传，但一定要这样做。
问题几乎肯定不会出现在Arduino代码中。 我运行了您提供的代码，以及我计算机上的RBL（红熊实验室）提供的草图。 我可以使用这两个草图连接到我的iPhone 。

我将列出我认为可能成为问题根源的所有内容：

确保所有的标头引脚（您应该有一堆标头从数字引脚旁边的3行中伸出电路板）正确连接，正如RBL在其说明中所示。如果你想让我提供我的照片，我可以做到。
确保盾牌上的白色电源指示灯亮起。如果不是，那么电源就不会进入屏蔽本身。
请确保您的手机确实启用了蓝牙功能。
您没有提到您下载了该应用。一定要这样做（RedBear称之为“BLE控制器”），因为如果没有应用程序就无法连接到iPhone（Apple的蓝牙菜单不会显示BLE防护罩）。
如果您已下载应用程序，请确保使用屏幕左上角的按钮从选项中选择了正确的设置（彼此顶部有3行）。对于您提供的草图，您应该选择BLE Controller。

如果您已尝试过所有内容而其他任何内容都无效，请尝试使用RBL提供的其他草图，例如SimpleChat。这使用Arduino上的串行监视器与iPhone来回通信。如果这不起作用，请上传特定盾牌的图片（顶部），以便我可以查看它。祝你好运。
