TI中文支持网请问：
uint8_t zclport_readNV(uint16_t id, uint16_t subId, uint16_t ndx, uint16_t len,void *buf)
中的subId – NV ID如何理解？
uint8 osal_nv_read( uint16 id, uint16 offset, uint16 len, void *buf );
这两者之间的id，分配规则，App中是独立的？还是延续
// NV Items Reserved for applications (user applications)
// 0x0401 ?0x0FFF
谢谢

回复 Susan Yang:
我想问的是：
uint8_t zclport_readNV(uint16_t id, uint16_t subId, uint16_t ndx, uint16_t len,void *buf)
黄色标记的 subid？
void zclGeneral_ScenesInit(void){ uint16_t x;
for(x = 0; x < ZCL_GEN_MAX_SCENES; x++) { zclport_initializeNVItem(zclSceneNVID, x, sizeof(zclGenSceneNVItem_t), NULL); }}
此处应用中的zclSceneNVID 为 0X0001，这是为什么？
其次subid 为 x ？
