Hi,

this code is entered when module detect break character, first part of LIN header sent by master. So if you are able to sent response from slave to this LIN header received, then you should be able to receive payload as well. Just call LIN_DRV_ReceiveFrameData from LIN_PID_OK event of callback as shown in slave demo example.

BR, Petr
