Hi. The lack of Serial.End() method is not critical in most cases. Its work is to deinitialize the hardware UART and release the controller pins that were connected to it.
It should be noted that the HardwareSerial class is static and calling the End() method does not free RAM. It is not difficult to add support for this method, but I would like to know how you want to use it.

我写了一段加密程序，简单的说，我是通过串口监视器输入密匙可以永久激活，一旦程序激活就关闭串口通讯，我在arduino UNO上试过了没有问题，在W806上使用发现不支持Serial.end();

@xiaoxuesheng I'm on an extended business trip right now. I don't know when I'll be back in my lab. This is a temporary solution, I don't have time for an in-depth study right now. Write about this problem to https://github.com/board707/w80x_arduino/issues.
