To reproduce

I am using Astrovim, and installed arduino language server with mason.

Expected behavior

For the Language server to start and work. Right now it doesn't. it can just make the syntax. But no completion

Arduino Language Server version

0.7.6

Arduino CLI version

arduino-cli Version: 0.35.3 Commit: 95cfd654 Date: 2024-02-19T13:24:18Z

Operating system

Linux

Operating system version

Linux Mint with i3

Additional context

No response

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest version
• My report contains all necessary details

I have the same issue. This LSP message gets displayed as soon as I open the .ino file:

Client 1 quit with exit code 2 and signal 0

This Arduino LSP was working fine a few months back.

I may have a possible fix. For everyone who is facing this issue, I was having the exact same issue, and JUST COULDN'T FIGURE IT OUT. But finally! I have managed to fix it for myself.

My config was just the fact that I was using NeoVim with the Arduino LSP, and the Arduino-cli to to upload sketches. But to check it out, I downloaded the official ide, and turns out that the LSP wasn't working EVEN THERE! So, I tried compiling a Hello, World program, and it showed me an error saying, "serial not found", turns out, my system-wide install of python was missing the pyserial library. Which is really simple to fix! Just try the
python3 -m pip install pyserial --break-system-packages.

Note: The pipx install didn't work, and had to use the --break-system-packages instead.
Just try restarting your IDE after it, and it should work!! If it doesn't, I recommend trying out by compiling a hello world program in the official ide!

[anmoljhamb]

@mroavi Let me know if my suggested fix works for you!!

[mroavi]

I already had pyserial globally installed 😔.

❯ python3 -m pip install pyserial --break-system-packages
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pyserial in /usr/lib/python3.12/site-packages (3.5)

I still get

Client 1 quit with exit code 2 and signal 0

when I open an .ino file in neovim.

Here is my LSP log:

I finally fixed my problem. When I updated the LSPs installed in my Mason setup, clangd was updated, and the path to its executable changed. I updated it to the new path, and everything works fine now. Sorry for the noise. The problem I was having is different from the one that the OP described. I assumed it was the same since we both experienced the issue on the exact same day. My mistake.
