Command format

Header + Length + Device identifier code + Command + Parameters + Checksum

Header: 2BYTE,0xAABB

Length: 2BYTE,Identification from the device identifier code to check word, The

device identifier code: 2BYTE, 0x0000

Command: 2BYTE, Identifies the coding command functions

Parameters: Command packets (can be empty)

Checksum: 1BYTE, Device identification to the parameter byte by byte XOR

Response:

Header + Length + Device identifier code + Command + Status + Parameters + Checksum

Header: 2BYTE,0xAABB

Length: 2BYTE,Identification from the device identifier code to check word, The first byte is valid,Second byteis reserved 0

Device identifier code: 2BYTE, 0x0000

Command: 2BYTE, Identifies the coding command functions

Status : 1BYTE,00 = Command OK, Nonzero = Command failure

Parameters: Command packets (can be empty)

Checksum: 1BYTE, Device identification to the parameter byte by byte XOR

Animal ID Format:

               14 bytes animal ID

               Animal ID format: National ID(5 Bytes) +

                                 Country ID(2 Bytes) +
