# Payload payload = mcr_data[chunk_start+5 : chunk_start+5+length-1] # -1 accounts for the type byte in length count? # Actually, length includes the type byte. So payload length is length - 1. # But standard logic is usually just strict slicing. # Let's just grab exact bytes. payload = mcr_data[chunk_start+5 : chunk_start+length+4] # +4 because length is payload+type
