Vscode-arduino: Unable to start serial monitor

[PeterWone]

Same symptoms as #851 but with 0.2.27 on VS Code 1.40.0

Same workaround -- manually edit arduino.json but this leaves you without Serial monitor. Better to revert VS Code to 1.39.2 and disable auto-update pending an update to this extension.

Looking at the related VSCode issue pertaining to the 1.36 breakage,

OK. This explains it. The problem is that the Arduino extension uses native node modules (which is not official supported right now in VS Code) and the node version of VS Code has changed. This basically means that the Arduino folks need to ship a new version of their extension.

It's the same problem with the same fix.

I just ran into the exact same behavior. Upgraded to VS Code 1.40.0 and my ability to connect to the serial monitor has been broken.

If you need to use the Serial monitor, you can always use the Arduino IDE instead as a workaround for that as well.

same error here when upgrade to 1.4.0

@PeterWone Thank you for reporting this issue.

We're currently investigating the root cause of this issue, probably because of the Electron and Node version upgrade in latest VS Code 1.40.

reverting to latest-1 solves the problem (for now)

We're currently working on a new release containing the fix to this issue, will update you once we release goes public.

The serial port issue has been fixed in the latest Arduino extension release (0.2.28).
Please install the latest Arduino 0.2.28 from marketplace https://marketplace.visualstudio.com/items?itemName=vsciot-vscode.vscode-arduino to verify if this is resolved on your environment.

[PeterWone]

Thanks for your efforts, I have tested vscode-arduino 0.2.28 with VSCode 1.40.1 and full compatibility has been restored.

I'm still having this issue. I get the following output when opening, but no values appear

@aubergene The problem does not occur for

Version: 1.40.2 (user setup)
Commit: f359dd69833dd8800b54d458f6d37ab7c78df520

Occasionally I've had problems after updating Node that were fixed by a reboot. If you reboot and you can still reproduce the problem then maybe you have versions of Node and paths are causing the wrong version to be used, but this seems unlikely given that 12.4.0 is being reported.

If all else fails then create a new issue and include the facts that it is platform specific and you have already tried these remedies.

having the same issue with Version: 1.43.1
just downgrade it to 1.42.1, it works normally.

Same here. I entered port details manually in arduino.json and uploading the Get Started code to the device seemed to work fine. The next step in Get Started Docs explaining to open serial monitoring fails completely though with this unhelpful error:

Failed to open serial port COM7 due to error: + Error: \\?\c:\Users\seefe\.vscode\extensions\vsciot-vscode.vscode-arduino-0.3.2\out\node_modules\usb-detection\build\Release\detection.node is not a valid Win32 application.
\\?\c:\Users\seefe\.vscode\extensions\vsciot-vscode.vscode-arduino-0.3.2\out\node_modules\usb-detection\build\Release\detection.node

Out of curiosity I fired up Windows Terminal and opened Azure Cloud Shell and used the az iot hub monitor-events command to point at my iothub and it seems telemetry is successfully being sent from the device. So, for now I guess one can use Azure Cloud Shell for serial monitoring purposes? It certainly seems to work, even when using Azure CLI via my current VS Code integrated terminal setup. Can anyone clarify whether this is a VS Code bug, an Arduino extension bug or both. It's making for an appalling user experience trying to follow the IoT DevKit Getting Started tutorial on Microsoft Docs site that's for sure.
