### uint8\_t Vector::BLF::Most50Pkt::transferType {}

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.
