I did capture the CAN signal with the Scope and found strange noise affecting the bus, could you help me understand which could be the reason?
Thanks.

Re: CAN signal
Hello,
this curve look quite good to me. There is a symmetrical overshoot when the bus changes from recessive to dominant, and it takes a little while until the signal settles when changing from dominant to recessive.
But the disturbance is far away from disturbing the signal. Detection level of a dominant signal is typically >0.7V (min. >0.5V) for the differential receiver voltage.
