stm32f4 UART HAL losing bytes

Posted on September 13, 2016 at 11:20

Hi All,

I'm working on stm32f411 borad with hal library.

I'm using the UART without knowing the exact size I suppose to get so I'm using HAL_UART_Receive_IT to get the first byte of the data and afterwards I use HAL_UART_Receive(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint32_t Timeout) for reading the rest of the data with timeout.

The problem is that every now and then I lose couple of bytes on the way although I see them on the scope.

Every idea will be much appreciated,

Gilad
