SimpleProfile_GetParameter && SimpleProfile_SetParameter

 /*********************************************************************
  * @fn      SimpleProfile_GetParameter       简单 profile 得到参数
  *
  * @brief   Get a Simple Profile parameter.  得到一个简单的profile参数。
  *
  * @param   param - Profile parameter ID     形参param：profile的参数ID
  *
  * @param   value - pointer to data to put.  This is dependent on
  *          the parameter ID and WILL be cast to the appropriate
  *          data type (example: data type of uint16 will be cast to
  *          uint16 pointer).
  *
  *
  *  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
  *  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。
  *
  *  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。
  *  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。

bStatus_t 的值在宏定义处被解释为BLE_STATUS_VALUES，下面是BLE_STATUS_VALUES的值的含义:

 /** @defgroup BLE_STATUS_VALUES BLE Default BLE Status Values
  * returned as bStatus_t
  * @{
  */
 #define bleInvalidTaskID                INVALID_TASK  //!< Task ID isn't setup properly
 #define bleNotReady                     0x10  //!< Not ready to perform task
 #define bleAlreadyInRequestedMode       0x11  //!< Already performing that task
 #define bleIncorrectMode                0x12  //!< Not setup properly to perform that task
 #define bleMemAllocError                0x13  //!< Memory allocation error occurred
 #define bleNotConnected                 0x14  //!< Can't perform function when not in a connection
 #define bleNoResources                  0x15  //!< There are no resource available
 #define blePending                      0x16  //!< Waiting

 #define bleInvalidRange                 0x18  //!< A parameter is out of range
 #define bleLinkEncrypted                0x19  //!< The link is already encrypted
 #define bleProcedureComplete            0x1A  //!< The Procedure is completed
 #define bleInvalidMtuSize               0x1B  //!< MTU size is out of range

 SimpleProfile_SetParameter 和上面这个函数类似！
