The snap provides three executables to test and analyze a j1939 network.
The snap provides three executable applications: demo1, demo2 and the
j1939sniffer. The demo application can be used to test the j1939
communication between two devices. Therefore sample messages are
generated by demo2, which are sent to demo1. Because of the proprietary
communication with some random node addresses, it is prohibited to
connect devices running the demo application to a real J1939 network.
Therefore the sniffing tool can be used. the sniffer is designed to
receive messages, but neither transmit messages nor claim an address.
With the Sniffing Filter receive messages can be filtered. The
Sniffing Filter is an extra J1939 message filter that bypasses the
J1939 stack to allow network monitoring without network interaction.
