getting esp32 to communicate with GraviTrax

[GravitraxRosie]

I'm completely new to MicroPython and esp32, before I have worked a lot with other types of arduino.

I'm looking to get a bluetooth bridge to my GraviTrax connect.
but I got stuck just after starting...
I'm able to connect to my esp32 from arduino lab for micropython and run a basic program from there and saved it in boot.py

Then I went online to download the packages needed for GraviTrax. (https://github.com/Ravensburger-Verlag-GmbH/GraviTrax-Connect)
Followed all the steps descriped
but when trying to run an example I get this error:

ImportError: no module named 'gravitraxconnect'

I figured it is because I don't have it saved on my esp32, so I followed all the steps descriped here: https://docs.arduino.cc/micropython/environment/modules/
only in step 6 it says:

mpremote connect mip install github:arduino/arduino-modulino-mpy

I was unsure how to replace the file with the thing I need, I tried several options:

mpremote connect COM9 mip install gravitraxconnect
mpremote connect COM9 mip install C:\Users\rosem\Downloads\GraviTrax-Connect-main\GraviTrax-Connect-main
mpremote connect COM9 mip install GraviTrax-Connect
mpremote connect COM9 mip install Ravensburger-Verlag-GmbH/GraviTrax-Connect
it all gives about the same error

mpremote: Package not found: https://micropython.org/pi/v2/package/6/gravitraxconnect/latest.json

please can anyone help me out???

update:
I figured the right way must be: mpremote connect COM9 mip install github:Ravensburger-Verlag-GmbH/GraviTrax-Connect
but still no luck, I looked further into it and noticed there is no package.json file in this folder, as there is in other folders on github
is there a way around?

It looks like you are trying to install a cpython module on micropython which has different packaging (requires package.json).
Even if you copy over all python files with mpremote the code will likely not work without modifications.

Aha that explains a lot , but that would mean that my project is impossible with current hardware :(

currently impossible, maybe, with an ESP32. Maybe ask Ravensburger about implementing a MicroPython version?
