Hi, I am using SDK to realize LIN slave node and communication. Is it possible to ignore the incoming LIN messages somehow? To disable the uart interrupt (LIN_LPUART_DRV_DisableIRQ) is not a solution for me because I would like to check the activity on the bus. Basically I do not need the content of the messages I need to know only that the master is still alive.

A slave node waits for the synchronization pulse, and then does synchronization using synchronization
pulse and process the message identifier. Then according to the ID, the slave decides what to do, either
to receive data or to transmit or to do nothing.

Hi, thank you. I have found the function where the PID is processed. I just need to set the action to ignore.
