J1939TpDatagram Struct¶

One fully reassembled J1939 multi-packet PDU as delivered by IJ1939TpChannel. Carries the transport-service context every J1939 application layer needs to route the message: the PGN of the announced data, the source address of the transmitter, the destination address (0xFF for BAM, the local address for TP.CM), and whether it was carried by TP.BAM or TP.CM.

public readonly struct J1939TpDatagram

Constructors¶

J1939TpDatagram(uint, byte, byte, J1939TpKind, byte[]) Constructor¶

Creates a new J1939TpDatagram.

public J1939TpDatagram(uint pgn, byte sourceAddress, byte destinationAddress, CanKit.Pro.J1939Tp.J1939TpKind kind, byte[] payload);

Parameters¶

pgn UInt32

sourceAddress Byte
