I have been using Eval STPM34 board for IOT Energy meter project. I need to to know the frame format used by the board to display the values in STPM3X Evaluation software. Help required to find out the No of bytes transferred through UART.

Can you not use one of serial port analyzer software to inspect the packets going back and forth? Seem to recall the SPI and USART packet forms being quite similar, having a CRC, etc.
