Hi there,

thanks for the quick answer
> please check http://www.can-wiki.info/doku.php?id=can_faq:problem_solving_questions

> Yes, retransmission is what the CAN controller always does if no other node is connected and gives a ACK to a correct received message

my main concern is the high system load it causes

Regards,
Viktor
