I am currently working on a internal project that involves understanding and demonstrating CAN bus-off attacks. I need some assistance in configuring and implementing a bus-off attack using MCP2515.

I am putting together a CAN Bus in one of my vehicles. My question is wire choice. I have a LOT of CAT 6 Ethernet and am wondering if I can use that instead of wire made specifically for a CAN Bus. I have found another answer that addresses using CAT 6, addressing the 100 ohm vs 120 ohm difference but his bus was going to be around 10 feet and the answer basically stated that it would because it is only about 10 feet and he would be using 100 ohm termination. His application is different so I don’t if it would work for my application.

I’m diving into the intricacies of CAN bus communication and came across the terms “Node ID” and “Frame ID.” While both seem to play crucial roles, I’m a bit confused about their differences. Could someone shed some light on this? And can I change the “Node (or ECU) ID”?
