One node can start to transmit, and can get interrupted by another node with a higher priority message. The interesting thing is that, even in case of interruption, the interrupting packet is not lost. And: the transmitting node which gets interrupted, even receives correctly the interrupting packet. After that, it will try again to transmit its original packet, the one which was interrupted. | |

So, if the first node-controller is only transmitting a packet, does the second node-controller have to be in receiving mode, or is it ok if the second node-controller has only the CAN-bus etc. initialized (but is not receiving any packet)? | |
