This was working fine with auto detect for the upload port until I plugged something in which created a COM3 port. That COM3 port is gone now but the uploader keeps trying to use it. The correct port is COM17. I added upload_port to the .ini file to force it but it still ignores it and tries COM3 then fails with the error:
CURRENT: upload_protocol = esptool
Looking for upload port…
Using manually specified: COM3
Uploading .pio\build\esp32dev\firmware.bin
esptool.py v4.5.1
Serial port COM3A fatal error occurred: Could not open COM3, the port doesn’t exist
*** [upload] Error 2
It shouldn’t be manually specified as COM3 (and never was). No matter what I try, it refuses to try COM17. Ato detection was working just fine until this mysterious COM3 showed up.
