关于attm_desc的问题
请教一下 n32wb03x_EVAL\ble\rdtss_16bit\src\app_profile\app_rdtss_16bit.c 下的这个表格，/* Characteristic Declaration */
[1] = {ATT_DECL_CHARACTERISTIC, PERM(RD, ENABLE) | PERM(WRITE_REQ, ENABLE),
0, 0},
最后的那个0，按照如下的定义，
struct attm_desc
{
/// 16 bits UUID LSB First
uint16_t uuid;
/// Attribute Permissions (@see enum attm_perm_mask)
uint16_t perm;
/// Attribute Extended Permissions (@see enum attm_value_perm_mask)
uint16_t ext_perm;
/// Attribute Max Size
/// note: for characteristic declaration contains handle offset
/// note: for included service, contains target service handle
uint16_t max_size;
};
应该是一个handle offset， 为什么不指向value的index（2）呢？
同问，为什么随便写个值，不影响使用？
那么，它是干嘛的？
