CC2540 Characteristic参数修改，如UUID、读写权限、数值

Hi, 大家好，有个问题想请教一下

---------------------------------------------------------------------------------

在SimpleBLEPeripheral项目中，有以下定义：

// Profile Parameters
#define SIMPLEPROFILE_CHAR1 0 // RW uint8 - Profile Characteristic 1 value
#define SIMPLEPROFILE_CHAR2 1 // RW uint8 - Profile Characteristic 2 value
#define SIMPLEPROFILE_CHAR3 2 // RW uint8 - Profile Characteristic 3 value
#define SIMPLEPROFILE_CHAR4 3 // RW uint8 - Profile Characteristic 4 value
#define SIMPLEPROFILE_CHAR5 4 // RW uint8 - Profile Characteristic 4 value

// Simple Profile Service UUID
#define SIMPLEPROFILE_SERV_UUID 0xFFF0

// Key Pressed UUID
#define SIMPLEPROFILE_CHAR1_UUID 0xFFF1
#define SIMPLEPROFILE_CHAR2_UUID 0xFFF2
#define SIMPLEPROFILE_CHAR3_UUID 0xFFF3
#define SIMPLEPROFILE_CHAR4_UUID 0xFFF4
#define SIMPLEPROFILE_CHAR5_UUID 0xFFF5

-------------------------------------------------------

当修改UUID及读写权限时(见红色文字)，如下，在iPad上用Lightblue作为Central连接之后，发现UUID还是修改前的数值，读写权限也没有变化，不知为什么？是否改的不对或是还有其它要修改的地方?

// Simple Profile Service UUID
#define SIMPLEPROFILE_SERV_UUID 0xFFE0

// Key Pressed UUID
#define SIMPLEPROFILE_CHAR1_UUID 0xFFE1
#define SIMPLEPROFILE_CHAR2_UUID 0xFFE2
#define SIMPLEPROFILE_CHAR3_UUID 0xFFE3
#define SIMPLEPROFILE_CHAR4_UUID 0xFFE4
#define SIMPLEPROFILE_CHAR5_UUID 0xFFE5

读写权限的修改：

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

改为：

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

----------------------------------------------

但是修改数值是可以的，在iPad上可以看到数值已修改：

#define SIMPLEPROFILE_CHAR2 11

----------------------------------------------

望各位高人指点，先谢谢啦。
