Arduino Nano 33 IoT Timeout Error

Development Tools IDE 2.x

Hi, I am using the Arduino Nano 33 IoT and I am getting this error when I try to upload any sort of code. It was working find until yesterday.

"Timeout. The IDE has not received the 'success' message from the monitor after successfully connecting to it. Could not connect to /dev/cu.usbmodem101 serial port."

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

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

  1. Select Arduino IDE > Quit Arduino IDE from the Arduino IDE menus if it is running.
    All Arduino IDE windows will close.
  2. Open macOS Launchpad.
  3. Type terminal in the "Search" field.
  4. Click on the "Terminal" icon.
    A "zsh" window will open.
  5. Type the following command in the zsh window:
    "/Applications/Arduino IDE.app/Contents/MacOS/Arduino IDE"
  6. Press the Enter key
  7. Wait for Arduino IDE to finish starting.
  8. Upload the sketch to your Nano 33 IoT, just as you did before.
  9. Wait until you see the "Timeout. The IDE has not received the 'success' message from the monitor after successfully connecting to it. Could not connect to /dev/cu.usbmodem101 serial port." error.
  10. Switch back to the Terminal window.
  11. Press the Command+A keyboard shortcut.
    This will select all the text in the Terminal window.
  12. Press the Command+C keyboard shortcut.
    This will copy the selected text to the clipboard.
  13. Open a forum reply here by clicking the "Reply" button.
  14. 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 output is correctly formatted.
    Code block icon on toolbar
  15. Press the Command+V keyboard shortcut.
    This will paste the output into the code block.
  16. Move the cursor outside of the code block markup before you add any additional text to your reply.
  17. Click the "Reply" button to post the output.

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