S32K314 LpUart interrupt

Hi,

I am using S32K314 board, in our project we are connecting to a Modem in which we want to enable interrupt and read the bytes received in the UART. I am using Lpuart_Uart_Ip_AsyncReceive but I don't know the exact number of bytes that receiving through my AT commands. How to implement interrupt for a normal modem connection?

You need to use the LPUART IDLE function. Maybe you can refer to the discussion in The S32K312 UART+DMA+IDLE No matter which UART sends, data is sent as 0

That project implement "UART receive indefinite length data".

Best Regards,
Robin
