Tranfer Type. Message-like events can either be recorded through the MOST transceiver chip or through a separate network spy.

  • 1: Node MOST transceiver reported the message (either due to a successful reception or as acknowledgment for a transmit request).
  • 2: Spy Message was reported by the network spy. The Spy sees all messages independently of the desti-nation address.
