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. ## Author Generated automatically by Doxygen for Vector BLF from the source code.
