Not possible to setup a coms port for uploading sketch

HendrikDijk · October 25, 2021, 3:09pm

Hello Team,
I was using Beta version 11 with a program for the NodeMCU 1.0 (ESP-12E module) at com11 and that is working fine. I can upload the software and see on the build in Arduino IDE serial monitor the data what is send to the monitor. I can even switch to different communication ports on the computer.
I update too version 12 and use the same setup and software as in Beta 11, I was not able to select a com port at all. In the option Tools there is no option available such as "port"or "serial" with a section option of the existing com ports. Also in the drop down section at the top "Select board & port" it is not possible to select a port.

I am still using windows 7

It happens sporadically with me. If I disconnect the processor from the PC and then reconnect it, the IDE finds a port again.
This is a small (annoying) mistake.

I have experienced something like this and reported it here:

topic: code type: imperfection

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

https://github.com/arduino/arduino-ide/issues/540 - https://forum.arduino.cc/t/not-possible-to-setup-a-coms-port-for-uploading-sketch/918369 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. ![image.png](https://zube.io/files/arduino/8b152a447d09edc0a87faff948c6a960-image.png) Thanks to [a tip from @RudolfAtHome](https://forum.arduino.cc/t/not-possible-to-setup-a-coms-port-for-uploading-sketch/918369/2?u=ptillisch), 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.

For me, the issue is only intermittent. If I close all Arduino IDE windows and then start the IDE again, the ports are then recognized. @HendrikDijk does the problem occur always for you, or are the ports recognized after restarting the IDE?

Thanks for mentioning this! I didn't notice that before, but I just tried it and it is the same for me. I have updated the issue report above with that information.
