连接设备的第一步是将 SPP LE 服务和特性添加到 LightBlue 中。要手动执行此操作，请在 LightBlue 中创建一个空白的虚拟外设，然后添加必要的服务和特性。另一个选项是在 SPPLEDemo 充当服务器的同时克隆 SPPLEDemo。要克隆 SPPLEDemo，首先如上所述连接 2 个设备。连接 2 个设备后，选择显示屏右上角的“Clone”选项。应用返回到设备列表，您将观察到 SPPLEDemo 列为虚拟外设，如下所示：

克隆后，SPP LE 服务现在可以与设备连接。接下来，重新启动 SPPLEDemo，并在出现提示时启动该应用作为客户端。下一步，使用 StartScanning 命令进行扫描以查找 iOS 设备。找到 iOS 设备后，使用 StopScanning 命令停止扫描。现在使用 ConnectLE 5c75524c733a 1 命令连接到 iOS 设备。之后，在 10 秒时间范围内运行 DiscoverSPPLE 5c75524c733a 命令。SPP LE 服务发现完成后，在 25 秒时间范围内运行 ConfigureSPPLE 5c75524c733a。如果命令未在这些时间范围内运行，iOS 设备将断开与 SPPLEDemo 的连接。配置 SPP LE 特性后，2 个应用保持连接，但请注意，如果 iOS 设备进入睡眠状态，则会关闭连接。运行刚刚介绍的命令后，在 SPPLEDemo 的终端中将观察到类似以下内容的输出：
