S32K118 CAN Transmit about ack

[종찬박]

Hi

I'm Jongchan.

I applied CAN communication in S32K1xx Seties Cookbook, Rev.4.

I found that CAN tx have tried to send all the time until there is ack.

and This situation is generated when CAN bus is off.

I want to know how to stop to send for check ack.

Hi,

this is behavior as per CAN standard. If the message is not ACKed from other node it is transmitted repeatedly. You can try to abort a message, refer to RM for more info.
