| 6 | Read length Inband: The maximum length of the electronic label that can be read is 501 (255 + 246) bytes. When the number of bytes to be read is greater than 246, the data needs to be read for multiple times based on the read offset. The length of data to be read at a time cannot exceed 246 bytes. Outband: The maximum length of the electronic label that can be read is 500 (255 + 245) bytes. When the number of bytes to be read is greater than 245, the data needs to be read for multiple times based on the read offset. The length of data to be read at a time cannot exceed 245 bytes. |
