// 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 5 value
#define SIMPLEPROFILE_CHAR6 5 // RW uint8 - Profile Characteristic 6 value-lyh
自己加了个SIMPLEPROFILE_CHAR6 ，
// 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
#define SIMPLEPROFILE_CHAR6_UUID 0xFFF6 //add by lyh
#define SIMPLEPROFILE_CHAR5_LEN 5
#define SIMPLEPROFILE_CHAR6_LEN //这个长度最大值可以写多少
自己添加的Characteristic，最大长度可以定义为多少？谢谢
