Brilliant! Just what I was planning to do, so your code is potentially a great time saver... Cool, thanks.

I tried it, I doesn't close the server and set the module to STATION mode
wifi.sta.getip() always gets "nil"
I am pretty sure if my network SSID and password

the code is not correct..

Code works. Just add a close server on whatever event you want. You don't need to put the device in station mode, it can be AP and Station.
