I am using LPUART1 for LIN communication and when it responses to&nbsp; a LIN header, after sending first data byte, it stops sending but&nbsp;"LIN_TX_COMPLETED" event does not occur. I have doupts on the LIN library because when I debug it , it goes only once to the&nbsp; "LPUART_Putchar" function. I am sending response to the header inside the LIN callback function. Can you please help me!</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="fcatkaya_0-1638521330701.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/164016i6C0BBA15B36B7349/image-size/medium?v=v2&amp;px=400" role="button" title="fcatkaya_0-1638521330701.png" alt="fcatkaya_0-1638521330701.png" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">fcatkaya_0-1638521330701.png</span></span></P><P>&nbsp;</P> Fri, 03 Dec 2021 08:51:48 GMT fcatkaya 2021-12-03T08:51:48Z https://community.nxp.com/t5/S32K/S32K116-LIN-timeout-problem/m-p/1381136#M13072 <P>Hi,</P><P>I faces a timeout problem in my LIN slave application that I use s32k116 MCU.

Just prepare response buffer and use&nbsp;LIN_DRV_SendFrameData as it is shown in example. Checksum is calculated within interrupt handler.</P> <P>BR, Petr</P> Mon, 06 Dec 2021 12:40:29 GMT https://community.nxp.com/t5/S32K/S32K116-LIN-timeout-problem/m-p/1381960#M13099 PetrS 2021-12-06T12:40:29Z
