tja1145 selective can wake up

i am trying to use selective can wake up of tja1145, I ran into a problem。

1 the computer send a can message to tja1145 with matched ID,tja1145 can wake up.

2 the computer send a can message to tja1145 with a unmatched ID first ,then send a matched ID,tja1145 can not wake up.

it is because when the computer send a can message to tja1145 with a unmatched ID, tja1145 will not respond to this message, and the result is that it will continue to send the can message with unmatched ID, even if i want to send a can messaage with a matched ID, it can not be send because the first can message is not sent successfully.

it seems that it is about the ACK bit in can message.

even if it is not a can message with a matched ID,can tja1145 respond to that message so the next can message can be sent? how?

Hi Jack.

I don't support this target.

I heard PPC5 team was very busy recently, I am not sure they have time to check community these days.

If your question is very urgent, I suggest you submit a case to NXP technical support team
