SimpleBLEPeripheral中的Characteristic 1 2 3 4 5的模式都是定死的吗？？

SimpleBLEPeripheral中的Characteristic 1 2 3 4 5的模式都是定死的吗？？

不能修改其中的参数吗？？为什么我把程序修改成这样还不能读出CHAR3的UUID

static uint8 simpleProfileChar1Props = GATT_PROP_READ | GATT_PROP_WRITE;

static uint8 simpleProfileChar2Props = GATT_PROP_READ| GATT_PROP_WRITE;

static uint8 simpleProfileChar3Props = GATT_PROP_READ | GATT_PROP_WRITE;

static uint8 simpleProfileChar4Props = GATT_PROP_READ | GATT_PROP_NOTIFY;

{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&simpleProfileChar1Props
},

// Characteristic Value 1
{
{ ATT_BT_UUID_SIZE, simpleProfilechar1UUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
&simpleProfileChar1
},

// Characteristic 1 User Descriptin
{
{ ATT_BT_UUID_SIZE, charUserDescUUID },
GATT_PERMIT_READ,
0,
simpleProfileChar1UserDesp
},

// Characteristic 2 Declaration
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,

},

// Characteristic Value 2
{

},

// Characteristic 2 User Description
{

},

// Characteristic 3 Declaration
{

},

// Characteristic Value 3
{

// Characteristic 3 User Description
