So, the problem was that we need to subscribes to "indication" in order to receive a response from the Nuki.
I also needed to add some time.sleep(2) after every char_write_handle and more sleep after the characteristics discovery. Don't know if this is only a problem with my raspberry pi 0, but anyway it is working (a bit slow) now with my Nuki v2.
Yes, it is ugly and inefficient, but it works (at least for me) ;)
I cannot test it with a Nuki v1 (I don't have it) but i guess it should still works.
If someone can test it, let me know.

I'll try to make it better if I'll find the time!
