COM port is blocked - Githubissues

RudolfAtHome commented 1 year ago

Describe the problem

Since version 2.0.3: The COM port is blocked even if the "Serial Monitor" is not used! I use an external program as a replacement for the Serial Monitor. That doesn't work anymore. I classify that as a mistake!

Up to and including V 2.0.2 the COM port was not blocked and I could use my external program. Now I have to close the IDE - that doesn't work at all.

To reproduce

IDE is open and I can download a sketch,
After that my external program has no access to the related COM port!
I must close the IDE to deal with my program

Expected behavior

Same as in V 2.0.2 and bevor: The IDE has to release the COM port after download. If one uses the integrated Serial Monitor, only than the port must be used too.

Arduino IDE version

Arduino IDE 2.0.3

Hi @RudolfAtHome. Thanks for your report. I am not able to reproduce this. Please provide more information:

Please provide detailed step by step instructions I can follow to reproduce the problem.
Which Arduino board?(s) are you using when you encounter this problem?
Does the problem occur consistently, or only intermittently?
Do you ever open the Arduino IDE Serial Monitor or Serial Plotter during the session (regardless of whether they are closed at the time you try to open the port using the external program)?

@RudolfAtHome - Does killing the serial-discovery.exe process in Task Manager (select it in "Details" tab and click "End task") give you back access to your COM port?
