@William-Scott Thank you for your great response we need more people like you on the internet.
First of all, sorry for not explaining myself enough or at least not the best I could've.
In summary, I would like the setup wizard as a tool to use it in other SBCs like the RPi.
The RPi creates a Wifi Network
You enter to the network
Put the credentials for the Wifi you want the RPi to connect
The RPi turns off its wifi network and tries to log to the new one.
Something along the lines of that. I think it should exist, but I don't know if that kind of process has a specific name which I can use to look around.
Ideally, I should work or thought to work on Linux computers (as most SBCs have some version of Linux available), this is kinda colors but yeah, some redundancy isn't bad sometimes.
Thank you again for your response.
