Pyfirmata 2 AUTODETECT only returns none

[AlboProgrammer]

Im new in programming with pyfirmata 2.
I have a Arduino Uno and want to controll it python.
Because we have diffrent computer and the Arduino has always a other Port we wanted that the Program to auto detect the right Port.
We can find the Adress from the arduino but the Programm gives us none back. What can I do?

I comment the part out because to test the other things.
I am Programming on Windows with Python 3.12

AUTODETECT is a constant (none):

it makes the constructor to detect it. If successful then all good. If not it throws an exception.

yeah, but this is what i become when i try run the programm:

when i do to find the comport myself , this i got in return:

it's not using any com port but only those which have the word "USB" in it as com ports are also used for other purposes. Perhaps your computer has a different description than "USB"? Can you check what description it returns? It could also be that you have either a newer or older version of pyserial which just returns something different for the description. If pyserial is very old then description might be blank. Just put a print statement in there and see what description gives you and report back. Thanks.

I saw you changed the pyfirmata2 Libary for the windows part.
I downloaded it and start the programm again. Now it come this in return:

I have pyserial 3.5.
Is this what you mean with describtion?

[berndporr]

I would like to know what d.description contains in your case:
https://github.com/berndporr/pyFirmata2/blob/master/pyfirmata2/pyfirmata2.py#L106
Or just add a print(l) here:
https://github.com/berndporr/pyFirmata2/blob/master/pyfirmata2/pyfirmata2.py#L96
and tell me.

[berndporr]

Even simpler. Run this:https://github.com/berndporr/pyFirmata2/blob/master/examples/scan.py

[AlboProgrammer]

I ran the scan.py and this i got in return:

[berndporr]

thanks. I've just added "Arduino" as a valid description. If you check out the newest version it should detect the COM port. Can you try?

967da5a it's here. Feel free to play around with it. Not at a computer with an Arduino so cannot check.

Thank you, its now working. Have a nice day
