- Is the filter for CAN messages before or after the receiver/ACK hardware?
- jk: ACK is always sent by all enabled nodes receiving a valid frame that are not the transmitter of the frame. Filtering only determines whether or not the received message gets stored in a mailbox, and for controllers with multiple filters, which mailbox. Filtering comes after the ACK is sent.
- pk: You may also have to set the acceptance filter much wider and do the final filtering in the software, the ACK mechanism would still not be an indication that someone is actually interested in your message.
