SDK 随附的《Software User's Guide》中详细介绍了BLE。除配置文件和服务外,您还可从Bluetooth Special Interest Group(SIG)网站免费下载BT 核心规范。尽管该核心规范多达2,000 页,但在开发蓝牙LE 应用程序的过程中通常仅引用几个章节:
 通用访问配置文件(GAP)-设定器件的作用(Peripheral, Central, Broadcaster,等):第3 卷,C 部分
 属性协议(ATT)-定义离散数据类型。这些数据类型是特征的“'building blocks”:第3卷,F 部分
 通用属性配置文件(GATT)-定义特征或属性使用的高效方法。第3 卷,G 部分
 安全管理器规范(SMP)-定义生成和交换安全密钥(也称为配对)的过程【可选】。第3卷,H 部分。Bluetooth SIG 有一些关于此主题的优秀博客,查看此处。
 链路层规范——管理器件连接的最低层,包括在开始连接时对链路进行加密并定义通道数据类型。第6 卷,B 部分
绝大多数与蓝牙核心规范相关的德州仪器在线支持社区询问都在核心规范的上述各节中解答。,上述各节介绍了经典模式以及双模式操作。有关仅针对BLE 的信息,请参见相应的介绍章节。
由于该标准的普及,也出现了很多专门介绍BLE 的技术书籍。可在您喜欢的书店的搜索引擎
中搜索“Getting started with Bluetooth Low Energy”。
