Listen-only means that this CAN node will not acknowledge incoming frames even if they are correct, it will just sit there and sniff passively. Loopback means that the hardware emulates a fully working bus (i.e. correctly terminated) with only one node that simply receives what it sen= ds. [Granted, documentation might be improvable here for CAN beginners. Still, you need basic some CAN understanding to deal with real-life issues anyway.] >=20 > When working with the virtual device. Does it matter which mode is chos= en? Nope, none of them is emulated so far.
