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?
br Martin
minor update: when I try to save the config, i get an error in console:
(ar4-py37) PS C:\........\Annin Robotics\AR4 HMI interface source> python .\AR4.py
Exception in Tkinter callback
Traceback (most recent call last):

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.
@martin-hermann Did you ever figure this out? I am having a similar communication issue after upgrading my AR3.
Make sure you’re using the correct baud
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.

Having almost the same issue, Unable to connect to teensy, if I put in the com port and click the button, the screen freezes and the circle just spins, as soon as I disconnect or reset the teensy it starts back again but still wont connect to the teensy
