I understand that you want to use MATLAB to work with the J1587 vehicle protocol,
MATLAB's Vehicle Network Toolbox primarily focuses on higher-layer protocols like CAN, CAN FD, J1939, and XCP messages., and it may not directly support J1587, which is a lower-layer protocol commonly used in heavy-duty vehicles.
You can also refer to the following documentation on Vehicle network toolbox if required,
Hope this Helps!
Thanks.
