A nearby approach without touching HAL code itself is, to call HAL_UART_Receive_IT(&huart3, &rxbuf, 1) once after initalization and at the end of the RxCpltCallback, to retrigger the reception, but this leads to some undesired lock (possibly a HAL-Bug), when transmitting data using HAL_StatusTypeDef HAL_UART_Transmit_IT(UART_HandleTypeDef. In this case, in your project, in folder 'STM32F7xx_HAL_Driver' will appear file 'stm32f7xx_hal_uart. simon burkhardt page 6 /6. Pressing the reset button, you can receive the data of the array aTxStartMessage. The follow diagram describes the transmitter state machine, this diagram is valid while the driver is in the UART_READY state.

You need to move the HAL_UART_Receive() to be before the HAL_DAC_SetValue(). modm: a barebone embedded library generator¶. HAL_UART_Receive_IT () is not meant to be called from an interrupt handler that way, but to initiate receiving a fixed number of bytes via interrupt. Also there is TCP server on ESP32 side, but I thinks its not the issue here. The product is easy to use, useful for all family members. For the compatible boards, the external SMPS significantly reduces power consumption in Run mode.
