I've been interested in RPis for a while, but I travel a bit and it's a huge hassle to onboard to a new wifi network. This is great, does it work for other RPis besides Zero?
What I would love is to do the RPi wifi configuration wirelessly, perhaps through bluetooth on my phone.
Are the OSs compatible between Zero and 3/4 Pi's? Maybe you could set up everything needed on a headed Pi and then pull its SD and slap it into the Zero, no funny phone apps.
