hi,各位大神：
最近我想使用Notification的方式通信，在编写程序的过程中遇到几个函数，比如：
bStatus_t GATT_Notification( uint16 connHandle, attHandleValueNoti_t *pNoti,uint8 authenticated );
uint16 GATTServApp_ReadCharCfg( uint16 connHandle, gattCharCfg_t *charCfgTbl );
bStatus_t GATT_WriteCharValue( uint16 connHandle, attWriteReq_t *pReq, uint8 taskId );
这几个函数里面都有一个参数connHandle,我一直没有搞明白这个参数到底是什么含义，应该如何获取？
如果我定义的Profile Attributes - Table如下：
static gattAttribute_t AttrTbl[SERVAPP_NUM_ATTR_SUPPORTED] =
{
/* Service*/
{
{ ATT_BT_UUID_SIZE, primaryServiceUUID },
GATT_PERMIT_READ,
0,
(uint8 *)&accelService
},
/* Declaration*/
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&TimeCharProps
},
/* Value*/
{
{ ATT_BT_UUID_SIZE, TransmitTimeUUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
(uint8 *)&DeviceTime
},
/* configuration*/
{
{ ATT_BT_UUID_SIZE, clientCharCfgUUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
(uint8 *)TimeConfigCoordinates
},
/* Declaration*/
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&DataNOTICharProps
},
/* Value*/
{
{ ATT_BT_UUID_SIZE, TransmitMACUUID },
0,
0,
(uint8 *)(&SendData)
},
/* configuration*/
{
{ ATT_BT_UUID_SIZE, clientCharCfgUUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
(uint8 *)DataNOTIConfigCoordinates
},
}
编程时为了使能peripheral的notification来上传Data，我想在central中将我上面定义的data特性的congfiguration值写入0x0001,那么我需要调用GATT_WriteCharValue函数，此时connHandle应该是多少或者怎么得到？如果我已经使能notification,那么我在调用GATT_Notification时，这里的connHandle又应该是多少？
