 2  * @fn      SimpleProfile_GetParameter       简单 profile 得到参数
 3  *
 4  * @brief   Get a Simple Profile parameter.  得到一个简单的profile参数。
 5  *
 6  * @param   param - Profile parameter ID     形参param：profile的参数ID
 7  *
 8  * @param   value - pointer to data to put.  This is dependent on
 9  *          the parameter ID and WILL be cast to the appropriate 
10  *          data type (example: data type of uint16 will be cast to 
11  *          uint16 pointer).
12  *
13  *
14  *  形参value：是一个空指针参数，指向输出数据的指针，这个依赖于参数的ID
15  *  并且 将被转换成适当的参数类似，例如：数据类型uint16将被转换成uint16指针。
16  *
17  *  profile:描述了某个应用场景中设备有什么功能（执行什么工作）。在一个profile里会定义好角色。
18  *  角色会包含一个服务service或者多个service或者没有。profile一般定义两个角色，例如防丢器中定义了一个报告者和监视者。
