Missing Baud Rate Dropdown v2.0.4 IDE

Development Tools IDE 2.x
1

Hi,

Appimage and gz versions of the 2.0.4 Arduino IDE are missing the drop down for baud rate selection in the serial plotter.
This is on two different computers both running KUbuntu.

Tested with version 1.8.19 it works fine. Also if a dev come accross this the detachable serial monitor was really good. The version 2x one really misses this feature.

Hi @sparksaregoodright. I'm going to ask you to post some additional information that might help us to identify the problem.

Please do this:

  1. Open a command line terminal in the folder that contains the Arduino IDE installation.
  2. Type the following command:
    • If you are using the Appimage package:
      ./arduino-ide_2.0.4_Linux_64bit.AppImage
    • If you are using the ZIP package:
      ./arduino-ide
  3. Press the Enter key.
    Debug output should now be printed to the PowerShell window as Arduino IDE starts (or fails to start).
  4. Wait for Arduino IDE to finish starting.
  5. Select your board from the Arduino IDE Tools > Board menu.
  6. Select the port of your board from the Arduino IDE Tools > Port menu.
  7. Open Serial Monitor.
  8. Verify that the baud rate menu is missing as before.
  9. Switch back to the terminal window if the Arduino IDE window took the focus.
  10. Use the mouse to select all the text in the terminal window. Make sure to scroll all the way up to the top.
  11. Press Ctrl+Shift+C.
    This will copy the selected text to the clipboard.
  12. Open a forum reply here by clicking the Reply button.
  13. Click the <CODE/> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.

  14. Press Ctrl+V.
    This will paste the output into the code block.
  15. Move the cursor outside of the code block markup before you add any additional text to your reply.
  16. Click the Reply button to post the output.

Please let me know if you have any questions or problems while following those instructions.

In general it indicates that your board is not detected. One reason is that the serial port is open in another application (or in another 'task' in the IDE).

I'll leave it further up to @ptillisch ;)

I often use Arduino Serial Monitor for anything serial not only arduino board. For example i was testing a AT Lora module via USB to serial TTL.
It is really useful good tool for that. I hope they don't remove this flexibility =)

Sorry Arduino folks for clogging up the forum -- I can put the post down to human error BLUSH.

For anyone else:
If you want to get the Serial Monitor working but for something else just make a new sketch, select an arduino board that you may use (or one you don't) but select something then select the USB/Serial port you want.

As long as the IDE has a board and a port you are good to go. You can just ignore the board.

Thanks.
