| 7:8 | Writing offset. The value starts from 0 and the LSB first. Write data in sequence when they are written as multiple frames. |
| 9 | Writing Length |
| 10:N | Command data The data format of each configuration item is as follows: Type: ID of a configuration item. Length: data length of a configuration item. Data: indicates the configuration item data. The first byte indicates the configuration result. The value 0 indicates success, and the value 1 indicates failure. The second byte and following bytes indicate the configuration item data.
