如何使用HAL_UART_Receive（）从stm32中的quectel L89 GPS模块读取数据？

Question

I am using STM32F103C8T6 board and CubeMX to generate the code. I need to receive the GPS data from Quectel L89 module from UART2 port. when I try that I get some junk values only... I am using HAL_UART_Receive to receive data and print it in the putty console. Any help would be greatly appreciated.

This is my code.

void task1(void)
{


char *buffer = NULL;
  buffer = (char*)malloc(400 * sizeof(char));
  while(1)
  {
  HAL_UART_Receive(&huart2,buffer,350,500);
  int size = strlen(buffer);

  HAL_UART_Transmit(&huart1,buffer,size,500);
  HAL_Delay(1000);
  }

}

Answer 1

try this

HAL_UART_Receive(&huart2,(uint8_t *)buffer,350,500);

and

HAL_UART_Transmit(&huart1,(uint8_t *)buffer,size,500);

Because arguments needed for HAL functions are of uint8_t * type.
