Hellow,
Firstly, VC-02 only supports UART. If you need to use RS232, you will need to add an additional level conversion chip. Secondly, if using serial port wake-up, secondary development is required. You need to set special receive instructions to wake up VC-02 and make logical judgments in the serial port callback function. Finally, thank you for using Ai-Thinker's products. If you have any questions, we will consult us promptly.
Yours,
