Hi Charles,
From what I can understand, you want to process a multi-packet transport protocol over the J1939 communication channel and want to capture the disparate values across a set of packets.
The vehicle Network toolbox provides several blocks that could be used to receive packets from different communication protocols, Since the transport protocol is over the J1939 communication channel VNT has a J1939 Receive block. The J1939 Receive block receives a J1939 message from the configured CAN device. Please look at the following documentation to understand the J1939 receive block.
Along with this have a look at the following documentation’s function segment to understand the different functions available to process the transport protocol.
For example, to receive all the available parameter groups from the bus by specifying a count of Inf.:
db = canDatabase('MyDatabase.dbc')
chan = j1939Channel(db,'Vector','CANCaseXL 1',1)
start(chan)
pgrp = receive(chan,Inf)
I hope this helps.
Regards,
Shivam Lahoti.
