Read size bytes from the serial port If a timeout is set it may return fewer characters than requested With no timeout it will block until the requested number of bytes is read
- python - PySerial: how to understand that the timeout occured while . . .
I'm using PySerial to read from serial port like in the code below CheckReadUntil() read output of the command that I send to serial port until the sequence of symbols readUntil are in the serial output self ser = serial Serial(comDev, 115200, timeout=10)

Access to the port settings through Python properties Support for different byte sizes, stop bits, parity and flow control with RTS CTS and or Xon Xoff Working with or without receive timeout File like API with “read” and “write” (“readline” etc also supported) The files in this package are 100% pure Python
- Reading serial data in realtime in Python - Stack Overflow
You need to set the timeout to "None" when you open the serial port: ser = serial Serial(**bco_port**, timeout=None, baudrate=115000, xonxoff=False, rtscts=False, dsrdtr=False) This is a blocking command, so you are waiting until you receive data that has newline (\n or \r\n) at the end: line = ser readline()
- Python PySerial I O - Setup, Interface, and Code Examples
ser read(size=1) Read size bytes from the serial port where size is the integer number of bytes to be read If a timeout is set it may return fewer characters than requested With no timeout it will block until the requested number of bytes is read ser readline(size=-1) Read and return one line in bytes

Read size bytes from the serial port If a timeout is set it may return less characters as requested With no timeout it will block until the requested number of bytes is read
- Communicating with serial devices using PySerial
To receive data from a serial device using PySerial, you can use the read() or readline() method of the Serial object Here are the steps to receive data from the serial device: In this example, we are setting the timeout period for reading data from the serial device to 1 second
- How to read and write from a COM port using PySerial?
import serial import time serialPort = serial Serial( port="COM4", baudrate=9600, bytesize=8, timeout=2, stopbits=serial STOPBITS_ONE ) serialString = "" # Used to hold data coming over UART while 1: # Read data out of the buffer until a carraige return new line is found serialString = serialPort readline() # Print the contents of the serial
