How to stop receive data in this code? or How to stop a get char? I used Interrupt to scan WiFi Information. I need only SSID. To input a buffer (Ring or FIFO) but it keeps bringing inform.

void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
  
  
  
  if(huart->Instance == USART2)
  {
    RX_Data[Rx_Index] = RXD;
    Rx_Index++;
    HAL_UART_Receive_IT(&UART2_WIFI,&RXD,1);
 
  }
 
}

Hello @wwgww​ 

Just call HAL_UART_AbortReceive_IT() function to abort any ongoing Rx transfer started in Interrupt.
