arduino-cli | Arduino command line tool

Using arduino-cli, the arduino-ide, or directly the esptool.py (from https://github.com/espressif/esptool) I obtain the following error when uploading a simple (correct) sketch.

Can anyone explain me how the arduino-cli daemon is working and what this is doing? I cant find any good documentation on the web...

When I start the daemon it only tells me, it started listening to some port.

Thanks for your help!!

I'm making a C# application that compiles Arduino code with arduino-cli. I'm calling it with the Process class using the ProcessStartInfo class and of course via cmd.exe which is absolutely necessary.

arduino-cli.exe ignores all arguments and outputs the following two lines for five seconds on starting it directly instead of running it via cmd.exe or from within a PowerShell console:

This is a command line tool.

You need to open cmd.exe and run it from there.

I can select the directory with the correct path, but when I select another directory to be compiled, there is output by arduino-cli.exe the error message:

Error: unknown command "Studio" for "arduino-cli"

I think that is because the directory I'm selecting is within a folder called Visual Studio Projects containing spaces in its name and I think it interprets each word as separate argument.

How to code the arguments passed via cmd.exe to arduino-cli.exe so that the two file names (input and hex file) containing spaces in their full qualified file names as complete argument strings?

I read online that if I add @ before the path it should fix it, but it hasn't done much.

This also happens when I run the arduino-cli command line directly in a Windows command prompt window instead aside from C#. The issue is likely with the command line syntax.

Here is my C# code:

I have a Linux machine running CentOS 7 with Python 2.7.5 installed. I am trying to run the Arduino-CLI, which is an executable that requires Python. I wrote a command to compile a sketch. As seen on the right side, it effectively compiles.

When I run the same command in PHP using sudo_exec(), it gives me:

Before people start crying "duplicate", I've already examined

• Spawning process with arguments in node.js
• Use NodeJS spawn to call node script with arguments
• How do I pass command line arguments to a Node.js program?

The first of these is basically the same question in a different use case and as a result the answers do not address my use case.

So... how do you encode a command line like the following with named parameters separated from their values by a space?

I'm trying to start a server daemon from within my js code, then to access it from the same program. However, when I use the execFile() method from the child_process module, this blocks the entire program: the execFile() call never stops, and I am unable to access the server. However, I know the daemon is started since I see a process of the same name start up from my activity monitor (macos equivalent of task manager).

I've also tried exec() and spawn() from the same module, and it gave the same results.

What I'd want to be able to do is to start the daemon as a separate process, forget about it, then stop it when I'm done using it. Is there any way I could do at least the first two?

Here is my code (the runArduino function is where I start the daemon, and the main() function is where I access it):

I'm trying to load .proto files coming from the arduino-cli repo. More specifically, I'm loading the commands.proto that has a dependency on a few other .proto files within the same directory.

In the load options provided to proto-loader, I specified the paths to all these .proto dependencies, yet an error pops up stating that proto messages defined in one of these dependencies are not defined.

Here is my code:
