Callback help

That code looks a lot cleaner, @countxerox!

Thanks for that advice @oesterle. I've had a go and I think it's improved but I can't close the wifi connection. wifi.disconnect() isn't recognized.

Well, at least it's perfectly OK to call wifi.connect() even when already connected according to the docs. And, your callback is called.

I wonder why wifi.disconnect() isn't working? @Gordon, any idea?
