ios - Red Bear Lab BLE Shield 无法连接到我的 iPhone

标签 ios iphone bluetooth arduino

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

我已将它连接到我的 Arduino，我正在尝试运行他们告诉我要运行的第一个测试程序，即 BLE Controller 草图。我已经连接它并解决了我最初得到的一些原始编译错误，现在它会上传。当我上传它时，我的 iPhone 对屏蔽没有反应。我想弄清楚问题是出在代码中还是防护罩本身的问题。如果是代码，我该如何修复代码？我对 Arduino 比较陌生，对让它与蓝牙一起工作完全陌生。这是指南告诉我从 Github 下载的整个草图。

最佳答案

在过去的 8 个月里，我一直在处理这些问题，所以我会尽我所能提供帮助。我没有评论和要求澄清具体事情的名誉，所以我只是想尽我所能。

让我们首先列出一些事情:

  • 因为您的草图已上传，我假设您已将所有必要的库添加到 Arduino。如果还没有，我不知道为什么要上传，但一定要上传。

  • 问题几乎肯定不会出在 Arduino 代码上。 我运行了您提供的代码，以及我电脑上 RBL(红熊实验室)提供的草图。 我能够使用这两个草图连接到我的 iPhone。

我将列出我认为可能是问题根源的所有内容:

  • 确保所有接头引脚(数字引脚旁边应该有一堆接头以 3 行的形式从电路板伸出)正确连接，如 RBL 在其说明中所示。如果您要我提供我的照片，我可以做到。

  • 确保防护罩上的白色电源灯亮起。如果不是，则电源不会到达防护罩本身。

  • 确保您的手机确实启用了蓝牙。

  • 您没有提到您下载了该应用程序。请务必这样做(RedBear 将其称为“BLE Controller ”)，因为如果没有该应用程序，您将无法连接到 iPhone(Apple 的蓝牙菜单不会显示 BLE 屏蔽)。

  • 如果您已下载该应用程序，请确保您已使用屏幕左上角的按钮(3 行彼此重叠)从选项中选择了正确的设置。对于您提供的草图，您应该选择 BLE Con​​troller。

如果您已经尝试了所有方法，但没有其他效果，请尝试使用 RBL 提供的其他草图之一，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，请上传您的特定防护罩(顶部)的图片，以便我看一下。祝你好运。
