Set and Start(Auto set bps)
c= 0xAA
c= 0x55
c= 0x12 -> Auto set bps
c= 0x03 -> CAN bps
c= 0x02 -> Type (1:Standard Frame/2:Extended Frame)
c= 0x00 -> Filter ID & 0xFF
c= 0x01 -> (Filter ID >> 8) & 0xFF
c= 0x00 -> (Filter ID >> 16) & 0xFF
c= 0x10 -> (Filter ID >> 24 & 0xFF
c= 0x08 -> Mask ID & 0xFF
c= 0x01 -> (Mask ID >> 8) & 0xFF
c= 0x00 -> (Mask ID >> 16) & 0xFF
c= 0x10 -> (Mask ID >> 24) & 0xFF
c= 0x03 -> Mode(0:Normal/1:Loop back/2:Silent/3:Loop back + silent)
c= 0x00 -> Only send once
c= 0x00
c= 0x00
c= 0x00
c= 0x00
c= 0x44 -> CRC
