not able to connect to teensy 4.1 from python
Hello all,
my electronic box build is based on AR4, but the robot is AR3. Therefore i use the AR4_teensy41_CUI skatch.
situation:
i can connect from Arduino (both (Arduino + Teensy) SW-packags installed) to Teensy to upload sketch:
but when i open the python AR4 Software and set the com to: 4 (and click on the button: "Set Com Teensy") it still shows the error message: "unable to establish communications with Teensy 4.1 controller:
any suggestions how to debug/check the connection?

Hello Simon, the baud rate is set in the app to 9600. my problem with the new app version is that I can not connect to Teensy when I select the correct com port. I still try to understand what the problem is.
somehow i wonder that it looks like that this problem is only on my end. even when i run a vm on win10, i have exactly the same issue.
anyway, I will post an update once i have some news on this.

note about the windows exe app: when i run the exe version, only a small window starts and the curser spins but the main app is not started.
