Only Store Credentials when necessary #29
Description
Message from Pete
Just sticking this here as a reminder - I've been looking through wifihandler.cpp and if I'm reading it right it stores the wifi details to preferences every time it connects. I can see why this is done on the first connection to an AP (as you only want ot store the credentials if it successfully connected but I'm worried that this, along with saving to preferences on every sleep, is could lead to early ageing of the flash. At some point we could do with changing this so that preferences are only saved when something changes.
