LPUART_DRV_CompleteReceiveDataUsingInt is not called.

[HyunungPark]

Hi.

I implement that the data send and receive through UART.

But there is an issue.

LPUART_DRV_CompleteReceiveDataUsingInt is not called after all data is received like the attached file.

below is the code which I implement.

but LPUART_DRV_GetReceiveStatus doesn't exits because LPUART_DRV_CompleteReceiveDataUsingInt is not called in the below code 

what do I resolve this issue?

==========================main=============================

LPUART_DRV_Init(INST_LPUART_1, &lpUartState2, &lpuart_2_InitConfig0);
/* Install the callback for rx events */
LPUART_DRV_InstallRxCallback(INST_LPUART_1, rxCallback, NULL);

while (1)
{

LPUART_DRV_ReceiveData(INST_LPUART_1, buffer, 1U);

/* Wait for transfer to be completed */
while(LPUART_DRV_GetReceiveStatus(INST_LPUART_1, &bytesRemaining) == STATUS_BUSY);

/* Check the status */
status = LPUART_DRV_GetReceiveStatus(INST_LPUART_1, &bytesRemaining);

}

========================api===============================

/* UART rx callback for continuous reception, byte by byte */
void rxCallback(void *driverState, uart_event_t event, void *userData)
{
/* Unused parameters */
(void)driverState;
(void)userData;

/* Check the event type */
if (event == UART_EVENT_RX_FULL)
{
/* The reception stops when newline is received or the buffer is full */
if ((buffer[bufferIdx] != '\n') && (bufferIdx != (BUFFER_SIZE - 2U)))
{
bufferIdx++;
/* Update the buffer index and the rx buffer */
LPUART_DRV_SetRxBuffer(INST_LPUART_1, &buffer[bufferIdx], 1U);
}
}else if(event == UART_EVENT_END_TRANSFER){

}
}

BRs.

Hi Hyunung Park,

Did you change the value of BUFFER_SIZE according to your needs? Otherwise the LPUART_DRV_SetRxBuffer in rxCallback will trigger continuous reception without enter LPUART_DRV_CompleteReceiveDataUsingInt.

Best Regards,
Robin
