Intermittent failure to recognize ports #573

per1234 · 2021-10-23T15:54:19Z

Describe the bug

From time to time, the IDE exhibits the follow symptoms when I open it:

No ports are shown under the IDE's board/port menu
The "Select Board" dialog (accessed via "Select Other Board & Port") shows "NO PORTS DISCOVERED"
The Tools > Port menu is missing

However there are multiple detectable Arduino boards and generic serial ports on my computer and other times when I start the IDE the ports are detected just as expected.

To Reproduce

Start Arduino IDE
Check if ports are listed. If so, then exit IDE and start again at step 1.

Command line looks like this when the issue occurs:

Expected behavior

All connected ports and boards are always shown in the IDE.

Additional context

Unfortunately, the issue occurs intermittently (maybe once every 10 open/close cycles) and I have not been able to identify any pattern to its occurrence. I have not noticed any correlation with

I have never had this problem with the Java IDE, even when I check it at the same time IDE2 is failing.

Thanks to a tip from @RudolfAtHome, I learned that new ports are still discovered when the IDE is in this condition, including previously unrecognized ports after disconnecting and then reconnecting the board.

This is fixed for me by builtin:serial-discovery@1.3.0, which is now in use by the nightly build of Arduino IDE 2.x.

These are the relevant changes:

builtin:serial-discovery@1.3.0 release: https://github.com/arduino/serial-discovery/releases/tag/v1.3.0
Change to Arduino CLI that causes it to use builtin:serial-discovery@1.3.0: Remove hardcoded builtin tools arduino-cli#1537
Update to that version of Arduino CLI in Arduino IDE 2.x: Update Theia, CLI and LS #610

jegjessing · 2022-06-15T14:58:02Z

I just downloaded version 2.0 RC7
I normally work with 1.8 but wanted to give 2.0 a try.

No matter what I select as board I still get no ports discovered. Since it works for 1.8 i suspect there is a bug in 2.0?

per1234 · 2022-06-15T15:03:34Z

Hi @jegjessing. Please try this:

Select File > Quit from the Arduino IDE menus.
Start the Arduino IDE.

Are the ports discovered after restarting the Arduino IDE? I have been noticing this problem lately, but it is always fixed for me after restarting the IDE.

jegjessing · 2022-06-16T03:34:09Z

You are right. It worked after restarting

It often happens on my Windows notebook when one of the boards is the Portenta H7. I reopen the issue.

Seeing this exact behavior on Linux. Restarting does not help. I'm already in the dialout group, etc. The board is recognized by the system USB driver. It's just the IDE that doesn't see the port, at all.

jayrabe · 2022-09-20T19:13:25Z

Is this still open? Any clues? I'm using IDE 2.0.0 and have also tried nightly build 20220920 and have the same problem: IDE starts, edits, works up to uploading, then gives "no upload port provided" error. No ports listed in IDE > Tools.
$ lsusb detects the board, but IDE "Select other board and port" dropdown says No ports discovered. Not fixed by restarting IDE, unplugging/reconnecting arduino, using different cords, etc.
Using Linux Mint 21

jayrabe · 2022-09-20T19:43:15Z

Here's some more info that is above my paygrade to understand, except it seems that when I plug in a board, it is at first recognized by serial-discovery, but then immediately told to remove the port.

I start the 20220920 nightly build IDE with terminal command ./arduino-ide, with no arduino board plugged in.
I plug in a board, and these lines are added to the terminal:

Hi @jayrabe. I see you also posted about this problem over on the Arduino forum:

https://forum.arduino.cc/t/arduino-ide-2-0-not-showing-ports/858267/8

We can use that forum thread for the purposes of investigating and supporting your problem.

jayrabe · 2022-09-21T01:47:48Z

Very good. Thanks.

If the board select dialog is listening on the backend's event, the frontend might miss the event when it comes up, although boards are connected and ports are discovered. Closes #573 Signed-off-by: Akos Kitta <a.kitta@arduino.cc>
