我正在使用 Adafruit Bluefruit Feather 构建一个设备,该设备收集数据,然后将数据发送到 iPhone,在那里进行读取和处理。我看过无数试图解释如何对设备进行编程的示例,但我似乎对如何通过蓝牙将设备连接到 iPhone 存在误解。
我们将此代码基于 Adafruit 示例之一,并尝试合并 Adafruit BLE Gatt 库 ( https://learn.adafruit.com/introducing-adafruit-ble-bluetooth-low-energy-friend/ble-gatt ),但它不起作用,这是我们第一次使用蓝牙。我们使用的 iOS 代码来自https://github.com/nebs/hello-bluetooth。我们没有对 swift 代码进行任何更改。欢迎任何建议。我们发现了很多关于将数据从应用程序发送到 arduino 的信息,但关于将数据从 arduino 发送到应用程序的信息有限。如果您能让我们知道我们是否走在正确的轨道上,或者在发送数据方面是否应该进行任何更改,我们将不胜感激。
