WebbSTM32 works in 3V3. – campescassiano. May 13, 2024 at 23:26. AFAIR, the last parameter of the HAL_UART_Receive_IT is how many bytes to be received to generate the interrupt. So, you are telling it to be 4 bytes, so the interrupt will be generated only after receiving the 4 bytes, otherwise you will not reach the HAL_UART_RxCpltCallback.
