I've a problem building pybluez[ble] where it crashes my PiZero-W as described in this thread:
It builds fine on my RPi3
I'm using Raspbian-stretch 2017-09-07 image.
Can I expect the card setup on the Pi3 to "just work" if moved to the PiZero-W
I'd just try it but I've the "official" PiZero case and a camera module, I had enough trouble getting the camera installed correctly that taking it apart again to swap SD cards is very unappealing!
