Also, Im using SoftwareSerial to set up a secondary serial terminal to see what the Arduino receives. However, whenever I send data from Pyserial or hTerm, it doesnt show up in the Arduino serial terminal. Open index.js and copy following contents (Change the serial port name appropriately). Ive already verified that data transmission from Arduino to the PC is possible, by using hTerm and PySerial. baudrate: baudrate type: int default: 9600 standard values: 50, 75, 110, 134. Open your WSL console and run following cmds. /dev/ttyUSB0 on GNU/Linux or COM3 on Windows. If your serial device is in loop-back mode (its writes back what it receives), you will see the following message on console Accessing COM port from NodeJsįor NodeJs we can use serialport package for serial port access. Ser.write(b'serail port on wsl \n') # write a string Print(ser.name) # check which port was really used Ser = serial.Serial('/dev/ttyS3') # open serial port mkdir wsl-python-spĬopy following code into hello.py import serial You can get the COM port number from device manager window. This should open a Python Shell window and you should be able to recieve serial data like this: You can. Any existing python program should work if we just change the serial port name to `/dev/ttyS`, where N is the COM port number. In IDLE, press Run->Run Module or just press the F5 key. We will use pySerial to connect with serial port.
