Python Pyserial Windows找不到端口 [英] Python Pyserial Windows No Port Found

问题描述

我刚刚尝试使用AT命令连接到USB移动设备以通过它发送短信.但是，当我在Windows操作系统中使用pyserial连接到它时，出现错误无法打开端口，找不到指定的文件.

I have just tried to connect to usb mobile to send sms through it using AT commands. But when i use pyserial to connect to it in a windows os, i get error could not open port, the file specified cannot be found.

>>> import serial
>>> ser = serial.Serial(0)  # open first serial port
>>> print ser.name          # check which port was really used
>>> ser.write("hello")      # write a string
>>> ser.close()  

即使我将0替换为其他任何值(例如0 -10或'com0'，'com1'等)，我仍然会得到未找到指定的错误文件，无法打开端口.

even if i replace the 0 with any other value, like 0 -10 or 'com0','com1' etc, i still get error file specified not found, port cannot be open.

pyserial文档中列出了一个命令，该命令列出了端口或允许您打开端口

There is a command listed in pyserial documentation which lists ports or allows you to open a port

python -m serial.tools.miniterm

python -m serial.tools.miniterm

该命令应该列出所有串行端口.但它什么也没显示.

This command is supposed to list all serial ports. But it shows none.

我的系统上有3个USB端口.是什么导致此问题.

I have 3 usb ports on my system. What is causing this issue.

推荐答案

我自己找到了解决方案.它非常简单，并且在问题中使用相同的代码..我被阻止了错误，因为我的设备管理器中没有调制解调器(诺基亚电话).尽管我已将手机插入USB，但没有安装诺基亚PC套件.安装诺基亚PC套件并连接诺基亚电话后，在设备管理器->调制解调器中，您的电话将出现.只需检查其属性->调制解调器，您会发现com5或任何数字.然后使用该ID进行连接.如果您不知道这一点，请进行迭代，直到找到合适的对象为止.

I found the solution myself. Its pretty simple and uses the same code in the question.. I was getting blocked error because there was no modem(nokia phone) in my device manager. although i had plugged in my phone into the usb, there was no nokia pc suite installed. Once you install nokia pc suite and connect your nokia phone, in device manager -> modems your phone will appear. Just check its properties->modem and you will find the com5 or whichever number. Then use that id to connect. If you dont know this, just iterate till you find the right one.
