Data packet content
Frame Trail of Data packet
03
Note: 0x02, 0x03 are defined as starting character, and 0x10 is defined as identification character of
0x02, 0x03. Therefore, in communication, in transmitted data (between initial character 0x02 and
ending character 0x03), prior to 0x02, 0x03, 0x10, 0x10 must be insert as data recognition. For
example, from starting character 0x02 to ending character 0x03, there is a raw data 0x020310; after
inserting identification character, it will be 0x100210031010.
