Which one should be subscribe to for updates?

As a workaround:

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

{
  "port": "COM3"
}

That's working only for flashing but not for serial monitor

This trick didn't work for me, I uninstalled the Visual Studio code, and reinstalled an old version, it was no longer a problem and disabled automatic updates ...

https://code.visualstudio.com/updates/v1_41

"update.mode": "none"

@Abneco This workaround works for me but does it exists a portable version of Visual Studio Code?

Right now because of this extension I installed "Visual Studio Code" old version specifically to use vscode-arduino and "Visual Studio Code Insider" for other projects, but I really wanted to simply have a portable vscode designed only for Arduino projects, but I can't find it so far. Telling my team to use a specific version of VSCode on their machine by uninstalling their ones is not acceptable.

Would be nice if this issue is fixed tho to avoid this workaround.

@fabnicolas I looked into doing this.

The issue is not in the Arduino extension but in one of its indirect dependencies. A rewrite to use the N-API indirect invocation of native libs is far from trivial due to the complexity of post-installation platform specific build (on which the current implementation relies).

I am currently building an alternative extension that does not suffer from this problem because it works in a completely different way, shelling command line utilities for native integration. This has been a great deal of work and I have not yet decided to make it available for free.

Personally, I also have to develop on a stable system, I find that this extension is promising but not mature enough, so I chose to work with platformIO https://platformio.org/ compatible with the latest version and much more stable , easy to configure ... PlaformIO has another small drawback, ... acceptable ... this is mainly due to the fact that you must respect c ++

Don't forget to disable or uninstall the Microsoft arduino extension before installing PlatformIO, they are not compatible together

There is a new project called Arduino Pro which is trying to build VS Code kind of IDE. But I would not jump ship personally for now.

[sukesh-ak]

Also Arduino has a new project for building a new command line. I guess that will become the main way to compile, flash etc in the future.

[CorentinPacaud]

Will this issue be fixed some day ? or just end of support ?

[kseyhan]

try rebuilding the plugin following the steps from #1113 (comment).

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

I plan to publish a release with this fix tomorrow, Oct 30.

[robotdad]

Resolved in release 0.3.3

As a workaround:

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

{
  "port": "COM3"
}

This prompts the error "The arduino.json file format is not correct."

[WenukaB]

This can probably be due to an issue with Arduino Installation. I had the same issue. I uninstalled the Arduino existing installation and installed the latest version (1.8.13) it fixed the issue.

[simonl65]

This is now fixed with vscode-arduino 0.3.3

[ryanlightbrighton]

Just installed this (v 0.3.4). I can't select serial port. I added com3 manually to the arduino.json but then I'm stuck on the other bug (can't open serial port)

[lomolisso]

i have the same problem @ryanlightbrighton

[adiazulay]

This is resolved in v0.3.5 see #1198 for installation instructions.
