Hi, I need your help, please:I'm using a STM32 and the STM32CubeIDE and I want to communicate the MCU and a FPS module R502 through LPUART (Low Power UART). When I send the correct packages, the FPS answers correctly (I check that reading via serie w...

I'm using STM32L072CZT6 and yes, I generated the code with STM32CubeMX. I've used this MCU before and UART like this time: generating with STM32CubeMX (last version, I guess) and writing code with STM32CubeIDE; and it's the first problem I've had.

I solved the bug adding a false delay (HAL_Delay() didn't work) after SET_BIT. It seems there it needs a wait. Here the code: /* Enable the UART Error Interrupt: (Frame error, noise error, overrun error) */ SET_BIT(huart->Instance->CR3, USART_CR3_EIE...

Thank you for your answers!I've tried some options you adviced me, but it doesn't work.In debug mode, I've seen that after "HAL_UART_Receive(lpuart)" I have an error code in my UART_HandleTypeDef. The error is 8, which means I have an overrrun error,...
