This is a very specific use case: I need the RPi zero w to generate a local Wifi network that my client will connect to from a smart phone, browse to a specific IP address and setup the second wifi connection through a web form (ssid & psk).
The idea is that my final product has no screen, and it needs to be configured by the user to reach its wifi network.
For now, I'm able to create a local wifi network (I only tried on B+), and use the ethernet port to reach the internet, but I will not have ethernet on my final product.
My question is: is that possible? and if so, how?
I'm open to other ideas to reach the same goal (why not Bluetooth...)
