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。 19 * 20 * 2016年12月15日09:09:14，GXP 21 * 22 * @return bStatus_t BLE_STATUS_VALUES 23 */ 24 bStatus_t SimpleProfile_GetParameter( uint8 param, void *value ) 25 { 26 bStatus_t ret = SUCCESS; 27 switch ( param ) 28 { 29 case SIMPLEPROFILE_CHAR1: 30 *((uint8*)value) = simpleProfileChar1; 31 break; 32 33 case SIMPLEPROFILE_CHAR2: 34 *((uint8*)value) = simpleProfileChar2; 35 break; 36 37 case SIMPLEPROFILE_CHAR3: 38 *((uint8*)value) = simpleProfileChar3; 39 break; 40 41 case SIMPLEPROFILE_CHAR4: 42 *((uint8*)value) = simpleProfileChar4; 43 break; 44 45 case SIMPLEPROFILE_CHAR5: 46 VOID memcpy( value, simpleProfileChar5, SIMPLEPROFILE_CHAR5_LEN ); 47 break; 48 49 default: 50 ret = INVALIDPARAMETER;//无效的ID 51 break; 52 } 53 54 return ( ret ); //返回函数调用的状态 是成功了 ，还是因为ID无效失败了 55 }
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:
1 /** @defgroup BLE_STATUS_VALUES BLE Default BLE Status Values 2 * returned as bStatus_t 3 * @{ 4 */ 5 #define bleInvalidTaskID INVALID_TASK //!< Task ID isn't setup properly 6 #define bleNotReady 0x10 //!< Not ready to perform task 7 #define bleAlreadyInRequestedMode 0x11 //!< Already performing that task 8 #define bleIncorrectMode 0x12 //!< Not setup properly to perform that task 9 #define bleMemAllocError 0x13 //!< Memory allocation error occurred 10 #define bleNotConnected 0x14 //!< Can't perform function when not in a connection 11 #define bleNoResources 0x15 //!< There are no resource available 12 #define blePending 0x16 //!< Waiting 13 #define bleTimeout 0x17 //!< Timed out performing function 14 #define bleInvalidRange 0x18 //!< A parameter is out of range 15 #define bleLinkEncrypted 0x19 //!< The link is already encrypted 16 #define bleProcedureComplete 0x1A //!< The Procedure is completed 17 #define bleInvalidMtuSize 0x1B //!< MTU size is out of range
SimpleProfile_SetParameter 和上面这个函数类似！
