说明：  BLE协议栈，在TI的这个开发工具包里边，顾名思义，是包含BLE协议代码的，实际上就是TI释放出来的软件库代码与demo程序以及部分文档的集合，里边的协议栈是不开源的仅提供了库文件供我们使用，不过他提供了很多软件代码，API函数，以及使用的例子
(In the development toolkit of TI, the BLE protocol stack, as the name implies, contains the BLE protocol code, in fact the software library code released by the TI and the demo program and the collection of parts of the document. The protocol stack in the inside is not open source only provides the library files for us to use, but he provides a lot of software code, API functions, and examples of their use)
