【问题描述】：
我正在尝试修改 Sony SDK 提供的 CameraRemoteSampleApp，以在界面中添加对光圈、iso 和快门速度的完全控制。
然而，此时所有相关功能都不受限制。 文档将这些功能定义为“在安装并使用最新版本的 PlayMemories Smart Remote Control 时可用”。
a) 智能遥控器已安装并运行，通过它连接智能手机和 wifi（Samsung Galaxy SIII）。
b) 我可以使用 SDK 示例应用拍照。
c) 使用可用 API 列表显示功能存在但不可用。
d) 直接调用其中一个函数会返回“现在不可用”。文档中没有此错误代码。
在这种情况下如何访问 ISO/F 值/快门速度功能？
