You collect the bytes in a buffer, and you assemble the word and content from there.

Find documentation for the protocol you're using, and apply that to the data stream you are capturing.

Data representation 101

can you please help me with an example like slave id will be 1 and address will be 0x002 and voltage address will be 0x003
