使用ser.close即可关闭串口 数据的写使用ser.write接口，如果写的是十六进制的数据使用bytearray来定义，如 writebuf = bytearray([0x55, 0xaa, 0x00, 0x01, 0x00, 0x00])读数据使用ser.read接口，一般会先使用in_waiting来判断下是否有数据，然后开始读 下面举一个例子，说明下我们在实际的使用...
A simple check that self.serial._port_handle is not None works for SerialTransport._poll_read() ```python if os.name == "nt": def _poll_read(self): if self._has_reader: if self.serial._port_handle and self.serial.in_waiting: # if self.serial.in_waiting: self._loop.call_soon...
A wait mask value of zero indicates that the client is not waiting for any events.The client sends an IOCTL_SERIAL_WAIT_ON_MASK control request to wait for an event in the currently set wait mask. The serial controller driver completes this request when an event in the wait mask occurs....

If port does not exist, or if it is in use, you will not be able to connect the serial port object to the instrument with the fopen function. example obj = serial('port',Name,Value) specifies options using one or more name-value arguments in addition to the input arguments in ...

To be paired via serial port, the module must be in the state of waiting for pairing. The module will use the received information to connect to the router and register in the cloud. The MCU sends the following command. FieldBytesDescription Header 2 0x55aa Version 1 0x03 Command 1 0x2A...

Then, we do the same thing as we did before: we read a line, decode it to string, and remove any trailing character. We’re not using the ser.in_waiting here, because for this specific application we know that the Arduino will send back some data just after it has received the strin...
