Arduino Create

I am a high school teacher and teaching Arduino with my students through E-learning. We are just starting and using Arduino Create. Students are having problems connecting to their Arduino Uno boards via USB (see attached screenshots) to their school issued Chromebook. Any ideas on what is causing this and how to solve it?

  • Your OS and version can be valuable information, please include it along with extra security you are using. Antivirus etc.
  • Always list the version of the IDE you are using and the board version if applicable.
  • Use quote or add error messages as an attachment NOT a picture.
  • How to insert an image into your post. ( Thanks sterretje )
  • Add your sketch where applicable but please use CODE TAGS
  • Add a SCHEMATIC were needed even if it is hand drawn
  • Add working links to any specific hardware as needed (NOT links to similar items)
  • Remember that the people trying to help cannot see your problem so give as much information as you can

COMMON ISSUES

  • Ensure you have FULLY inserted the USB cables.
  • Check you have a COMMON GROUND where required. ( Thanks Perry)
  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
  • Try other computers where possible.
  • Try other USB leads where possible.
  • You may not have the correct driver installed. CH340/341 or CP2102 or FT232 VCP Drivers - FTDI
  • There may be a problem with the board check or remove your wiring first.
  • Remove any items connected to pins 0 and 1.

COMPUTER RELATED

  • Close any other serial programs before opening the IDE.
  • Ensure you turn off any additional security / antivirus just to test.
  • There may be a problem with the PC try RESTARTING it.
  • You may be selecting the wrong COM port.
  • Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.
  • Clear your browsers CACHE.
  • Close the IDE before using any other serial programs.
  • Preferably install IDE’s as ADMINISTRATOR or your OS equivalent

ARDUINO SPECIFIC BOARDS

  • CH340/341 based clones do not report useful information to the “get board info” button.
  • NANO (Old Types) some require you to use the OLD BOOTLOADER option.
  • NANO (ALL Types) See the specific sections lower in the forum.
  • NANO (NEW Types) Install your board CORE’s.
  • Unless using EXTERNAL PROGRAMMERS please leave the IDE selection at default “AVRISP mkII”.
  • Boards using a MICRO usb connector need a cable that is both DATA and CHARGE. Many are CHARGE ONLY.

CREATE editor install locations.

  • On macOs ~/Applications/ArduinoCreateAgent-1.1/ArduinoCreateAgent.app/Contents/MacOS/config.ini
  • On Linux ~/ArduinoCreateAgent-1.1/config.ini
  • On Windows C:\Users[your user]\AppData\Roaming\ArduinoCreateAgent-1.1

Performing the above actions may help resolve your problem without further help.

This seems to only be an issue with their school issued Chromebook. When I plug it in to my teacher's school issued laptop the Arduino board connects via USB with no problems (see attached). Any ideas on how to fix the issue with connection via USB on their Chromebook?

It may be a policy / restriction set by your IT department.
That said I have put the issue upstairs to see if they have anything to add.

Thank you for the input! We do pay for / subscribe to the Arduino Create App for Education. I have our IT department looking at it as well.

I do not think this problem is limited to a restriction set up on school chromebooks. My children and I were working on personal chromebooks and a couple of weeks ago our arduinos connected through the USB with no problem. We uploaded several programs. We tried again today and the Arduino is not seen by the chromebook. I have read elsewhere that a recent update to the Chrome OS may be causing the problem. We are stuck and unable to upload. Please advise.

I will push this upstairs ready for them to look at in the morning.

Hi @amynoble00,
there's a regression bug introduced in Chrome OS 85. The current stable Chrome OS version 85.0.4183.83 is affected.
The issue is caused by the Chrome OS serial API (chrome.serial.getDevices()) that the Arduino ChromeApp uses to list the devices connected to the serial port.
The Chromium team released a fix in the Chrome OS version 86.0.4210.2, currently sitting in the beta channel and scheduled to be released as stable in Oct 6.

Thank you for the info! I was able to update to the current Chrome OS beta version and now all of our Chromebooks are able to find the Arduino and port. Fixed. Thanks ballscrewbob and smellai!

Hi,

We have released an update on the app that fixes the error caused by Chrome OS on most of the boards.
Download the latest version of the app 1.0.15.12 to test it out.

Please let us know if you have an official Arduino board that is still not being detected by contacting us here.

Best Regards,
Therese
