Overview
The CANBus Triple is controlled by sending commands over the USB Serial connection, or over the Bluetooth LE Serial Service. Output will always be returned over the last serial interface that recieved data. The only exception is packet logging. Packets will always be sent over USB Serial unless they match the filters set vis the 0x04 command outlined below.
