UART_Lpuart_Uart_Ip_AsyncReceive_loss_packet

[xianlong]

Hi,all

The UART disables the transceiver when the reception is complete and starts again in Lpuart_Uart_Ip_AsyncReceive. If my data is sent too fast, there will be packet loss phenomenon,
How to solve this problem?I use 230400 baud rate

Hi xianlong,

Sorry for my delay!
Lpuart_Uart_Ip_AsyncReceive receive multiple bytes of data using a non-blocking method. If RxSize bytes have received, it will enter LPUART_UART_IP_EVENT_RX_FULL rx callback.  Lpuart_Uart_Ip_SetRxBuffer() can be called from the rx callback to provide the driver with a new buffer, for continuous reception. It will change the value of RxSize so that it will not enter line 1261 then disable rx logic.

Best Regards,
Robin
