I normally short-circuit CAN low and high to trigger bus-off. >>> I'm reading the CAN specification, but still not reaching to clear testcase. >> I don't understand yet what your problem is. > > Sorry, perhaps I didn't explained it very well. > So.

Maybe there is a betetr method to realibly get a bus-off. > Is there any irc channel with topic CAN ? I personally don't use IRC.
