Hi,

I've a question regarding the HAL UART Environment. I could observe that the Interrupt are raised sometimes 2x although  I'm sending only one Byte for the STM32 where I'm reading each single byte.

At which conditions can this happen?

Perhaps you can illustrate with some code and diagrams?

Does this occur on a continuous basis, or just when you first initialize the USART?
