Recently, I've encountered problems with 'HAL_UART_Receive_IT()'. So I go here for solutions. I see several suggestions to put another "HAL_UART_Receive_IT()" in "HAL_UART_RxCpltCallback()", but they didn't give which version of cube library they are using. So, I want to know the current status of this function in ST's cube library. Is this solution or 'trick' still necessary? The library I'm using is STM32Cube FW_F4 V1.21.0.
BTW: Hope that anyone who see this question can add the library version or other informations useful to your questions when asking. Because your question may reveal a *bug* in the library, and ST is continuously updating the versions of their library, so the bug exist today may don't exist tomorrow. These may help others with similar problems. And it's better if ST can provide a bug report system.
