可以参考我个性签名档的博客地址，《CC2541之notify》、《CC2541之indicate》。
里面解释了你想知道的CCC（client characteristic configuration ）。

你好，
因为你压根没设置notification的值
notification里面的值需要你自己去定义的：
软件设置如下所示：
第一在SimpleProfile_AddService函数里面高亮部分：
bStatus_t SimpleProfile_AddService( uint32 services ){ uint8 status;
// Allocate Client Characteristic Configuration table simpleProfileChar4Config = (gattCharCfg_t *)ICall_malloc( sizeof(gattCharCfg_t) * linkDBNumConns ); if ( simpleProfileChar4Config == NULL ) { return ( bleMemAllocError ); } // Initialize Client Characteristic Configuration attributes GATTServApp_InitCharCfg( INVALID_CONNHANDLE, simpleProfileChar4Config ); if ( services & SIMPLEPROFILE_SERVICE ) { // Register GATT attribute list and CBs with GATT Server App status = GATTServApp_RegisterService( simpleProfileAttrTbl, GATT_NUM_ATTRS( simpleProfileAttrTbl ), GATT_MAX_ENCRYPT_KEY_SIZE, &simpleProfileCBs ); }
2在
bStatus_t SimpleProfile_SetParameter( uint8 param, uint8 len, void *value )函数里面：
case SIMPLEPROFILE_CHAR4: if ( len == sizeof ( uint8 ) ) { simpleProfileChar4 = *((uint8*)value); //One choice // See if Notification has been enabledGATTServApp_ProcessCharCfg( simpleProfileChar4Config, &simpleProfileChar4, FALSE, simpleProfileAttrTbl, GATT_NUM_ATTRS( simpleProfileAttrTbl ), // INVALID_TASK_ID, simpleProfile_ReadAttrCB ); // the other choice dValue = GATTServApp_ReadCharCfg( notify_Handle, simpleProfileChar4Config );//读出CCC的值 static attHandleValueNoti_t pReport; if ( dValue & GATT_CLIENT_CFG_NOTIFY ) //判断是否打开通知开关，打开了则发送数据 { pReport.handle = simpleProfileAttrTbl[11].handle; pReport.len = 1; //osal_memcpy( pReport.pValue, &simpleProfileChar4, len); //数据 pReport.pValue[0] = simpleProfileChar4; GATT_Notification( notify_Handle, &pReport, FALSE ); } } else { ret = bleInvalidRange; } break;
