Hi @EvgeniyVol, can you please provide some more details? How are you executing the monitor? Are you using some IDE shortcut? Or are you executing the command in the integrated terminal of IDE?

If you are using some button in the IDE to execute the monitor, please make sure that you have followed the installation guide on the Clion website: https://www.jetbrains.com/help/clion/esp-idf.html

Please ensure you can execute the monitor using the idf.py monitor or python -m esp_idf_monitor command. Note that both commands need to be run in the ESP-IDF environment. Both the command line and PowerShell should work in this case.

1. IDE CLion 2024.1.4
2. I use the configuration in the upper right corner and the build button
3. Everything works in IDE terminal
4. I did as it says it doesn't work https://www.jetbrains.com/help/clion/esp-idf.html
5. In command line everything works

If everything works in the terminal, I am afraid that we cannot do anything about that from the ESP-IDF side. Please report the bug to CLion.

It is interesting that the linked page has a video tutorial and this issue is not happening there. IDF Monitor requires STDIN to be connected to it from the very beginning because it is an interactive tool and is not just receiving but also sending characters to the ESP. So I guess something must have changed on the Clion side. I agree that this should be address on their side.

However, we might think about to add a non-interactive mode for IDF Monitor in the future when it won't send anything and those related features would be disabled. Or if no STDIN is attached then disable those features with a warning.
