Well, you reminded me and I checked my code. It was done by myself 
explicitly in fact. I have
a script to initialize the real-time environment which started the CAN 
device
and set the bit rate, and I set the bit rate again in my application.
It's my fault to start this thread and waste your time. Sorry for that.
Beg your pardon!

If I have a chance to travel to the Europe one day, I really want to 
have a visit on
you guys. If you come to China, especially Beijing, Wuhan, Shenzhen, 
don't hesitate to contact me, I am glad to help :)

Have a good day!
