As a workaround:

open the folder where your .ino file resides
open the .vscode folder
edit arduino.json
change the port
e.g.

{
  "port":"COM4"
}

Roberto6969 · 2020-09-21T19:14:50Z

Thank you for your advice but this is not a solution. It doesn't resolve the problem. You can set COM port manually but if VSC can't open serial port, manual setting is of no use.

iqapps · 2020-09-22T07:05:09Z

Me same problem. Node.js version is wrong...

Downgrading to 0.30 restores expected function. (Damn, not anymore, now its completely useless.)

koderian · 2020-09-23T02:03:26Z

Same problem, it says

Failed to open serial port COM4 due to error: + Error: The module '\\?\c:\Users\my username\.vscode\extensions\vsciot-vscode.vscode-arduino-0.3.2\out\node_modules\usb-detection\build\Release\detection.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 75. This version of Node.js requires NODE_MODULE_VERSION 80. Please try re-compiling or re-installing the module (for instance, using npm rebuildornpm install).

I don't think it did this before.

hi @dilin-MS
Is there someone looking into this show-stopper bug?
This not just fails but takes almost 5mins to go to the next step to compile/flash from below line of error.

Not sure why its trying to "SerialDiscovery" when serial is already mentioned in arduino.json
If not its time to ditch this extension and move to PlatformIO again.

dilin-MS · 2020-09-24T02:52:12Z

Hi @sukesh-ak , the failure of device discovery is due to VS Code's latest version 1.49.1 upgrades the Electron version to v9, causing the serialport function failure. Refer to #1097 for details.
Currently @robotdad is help looking into the issue.

A Workaround is to downgrade the VS Code to a version which Electron version lower than v9. The issue will be fixed once the related serialport libraries upgrade to use Electron v9. Thank you.

Thank you @dilin-MS for the response.
Although the serial monitor issue is fixed after reverting to VS Code version v1_48 the error I mentioned and failure plus delay in next steps still exist.

Switch to VS Code 1.48 and see if it gets fixed. At least that issue is fixed after I down graded to 1.48

simonl65 · 2020-09-24T19:09:53Z

@sukesh-ak I hope the downgrade to 1.48.2 has got the serial monitor working for you - it has got mine working +1

Regarding your other error: that appears to be an issue with the arduino website - https://builder.arduino.cc/builder/v1/boards/0x10C4/0xEA60 comes back with a 404 Not Found error -1

sukesh-ak · 2020-09-24T19:13:55Z

Yes serial monitor is working now.

Where is that 404 call getting triggered (thought its part of this extension)?
This hits a delay of couple of mins before it proceeds to next step. So its still a blocker for using.
Since its working fine from Arduino IDE

simonl65 · 2020-09-24T19:19:10Z

I have no idea where that call's being made, but I think it may be a "red herring" anyway - I've just noticed that it does the same for me!

The next step after that call appears to be the verify or compile step. For me that part takes about 15s, but I suspect it depends on the size of your code?

simonl65 · 2020-09-24T19:20:25Z

~~Actually, the next step is Preparing boards...~~
Oops - nope, that's just before the error - my bad

15seconds feel like a day :)

I am guessing that's trying to automagically detect the port/board, wonder why when its already selected through this extension.
I also saw that, Arduino is moving to a new CLI option for compile/flash etc.

simonl65 · 2020-09-24T19:24:09Z

15seconds feel like a day :)

Haha - yes it does!

dannystaple · 2020-09-27T12:23:17Z

It feels like this should be marked as a duplicate of 1097 - since the behaviour here leads to that when I manually specified the port. Perhaps a note at the top of 1097 to state that being unable to select a port is a symptom of the same root cause?

fidelbrea · 2020-10-01T00:53:44Z

Downgrade. This is a solution. I fixed it by downgrading up to 1.48.2.
I hope you find this useful to fix your own situations.

scarolan · 2020-10-08T12:49:01Z

Confirmed that the downgrade to 1.48.2 solves this issue on Windows 10. Thank you all for doing the research.

EDIT: Well, not quite. The terminal opens the serial port now but there is no output.

[Starting] Opening the serial port - COM11
[Info] Opened the serial port - COM11

When I disconnect it and open the Arduino IDE serial monitor, I see all the expected output.

jonnytest1 · 2020-10-11T03:04:09Z

for those that dont want to downgrade :
i made a small project that uses the internal serialport package

this at least prints out the serial

there is currently no thought out config so just edit the COM3 to your com port and the baudRate in the index.js directly -

index.js

let chars = []

const port = new serial("COM3", { baudRate: 9600 }, (e) => {
    if(e) {
        console.error(e)
    }
})
port.on('readable', function() {
    chars.push(...port.read());
    printChars();
})

function printChars() {
    const newLine = chars.indexOf(10);
    if(newLine != -1) {
        const line = chars.splice(0, newLine + 1);
        let lineStr = "";
        for(let i = 0; i < line.length - 1; i++) {
            lineStr += String.fromCharCode(line[i]);
        }
        console.log(lineStr)
        printChars();
    }

    globalThis.write = (line) => {
            port.write(line)
    }
}```


package json:

{
"name": "serialmonitor",
"dependencies": {
"@types/node": "^14.11.8",
"serialport": "^9.0.1"
}
}

create the 2 files in the same folder
run npm install
open launch/debug view (ctrl shift d)
add config to your workspace (Node JS Launch Program)
adjust launch json like this :
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"program": "${workspaceFolder}\\index.js",
}
then just press f5 in the workspace

sukesh-ak · 2020-10-12T20:36:21Z

@jonnytest1 Can you explain a bit more on how to use this?

@jonnytest1 I don't want do downgrade, because all the time I have

(already reported as #1051)

and I need to upgrade (because then propably this fix #1051 as in #1050).
Could you give more info how can I fix this on my own?

iqapps · 2020-10-14T11:58:16Z

@rrakso thanks, and very interesting, because I didn't know how to make such handy extensions. I have to look more into this.

But this dosn't enable Arduino programming (CTRL+ALT+U) and it doesn't allow sending (CTRL+SHIFT+S) also - right ?

jonnytest1 · 2020-10-14T12:05:40Z

But this dosn't enable Arduino programming (CTRL+ALT+U) and it doesn't allow sending (CTRL+SHIFT+S) also - right ?

this actually is not really a vscode "extension" but a small node project

and yes netiher puihsing a c program (which is already working in the extension in here)
nor sending data(which probably takes about 10 lines of cose to add tbh ) is currently supported

if sending data is a big plus for you I can look into it - shouldnt take long as its more or less just the reverse of reading

iqapps · 2020-10-14T12:17:04Z

It more the matter of programming the Arduino that is the problem. But thanks.

I would rather have somebody to make this problem go away, so we can have trustworthy updates on the fly.

I would help myself if I could, but VS Code coding is way out of my comfortzone.

jonnytest1 · 2020-10-14T12:21:00Z

oh lol adding sending data was really easy :D

globalThis.write = (line) => {
port.write(line)
}

just adding these lines

and you can put
write("asf")
in the debug console and it will get forwarded to the serial port

tested with this code snippet: output changed after the write call for 3 characters

int incomingByte = 0;

void loop()
{
    Serial.println("test2");

    incomingByte = Serial.read();

    // say what you got:
    Serial.print("I received: ");
    Serial.println(incomingByte, DEC);

    delay(1000);
}

jonnytest1 · 2020-10-14T12:26:25Z

@rrakso sorry i dont know how to "fix" the original extension (not that i didnt try :3)
the way i did it is just a workaround that reimplements the functionality in a new project

jonnytest1 · 2020-10-14T12:27:25Z

i also noticed that unfortunately its necessary to close the serial monitor project while pushing a new program to the arduino

marcelo-lara · 2020-10-18T21:40:34Z

Anyway, is a patch for this issue coming in the next release?

kseyhan · 2020-10-20T19:57:56Z

for everyone suffering try rebuilding the plugin following the steps from my #1113 (comment).

robotdad · 2020-10-29T18:39:01Z

Prerelease build for the serial port issue is here: https://github.com/microsoft/vscode-arduino/releases/tag/v0.3.3-rc

Kwieeciol · 2021-08-13T19:15:14Z

Doesn't really work for me, freshly installed the extension, I uploaded the code (btw I couldn't select the board, the menu wouldn't just open, I needed to update the arduino.json file manually), but I cannot open the serial monitor, error message:

DeltaC6 · 2021-08-20T20:22:26Z

I am getting the following error. I have the latest VSCode installed with the latest Arduino extension.

I tried switching to an older version of Arduino extensions but none of them is working. Haven't changed VSCode to the older version yet.

manureichel · 2021-08-21T16:27:35Z

I'm having the same problem with a fresh installed VScode + Arduino Extension. I have to manually edit the json file to upload the code. I can't open Serial Monitor or manually change the COM. Same problem as @DeltaC6 an @Kwieeciol. There was an update or something? This used to worked fine for me a few weeks ago.

manureichel · 2021-08-25T23:22:47Z

I've solved the problem by downloading Visual Studio Code Version 1.58 (June 2021) . There was something in the July 2021 update that kept Arduino extension from working. Hope this works for you guys too.
