With html5 I know it's possible using the code below, but obviously there isn't a file structure in the code like there is on a computer. So how would I do this?
<a href="path/to/the/download/file" download><input type="button" value="Download"></a>
I'm aware of a few datalogging sites, which works, but I would like to be able to setup the 8266 as an AP and not have to worry about if there will be wifi for me to connect to and programming in the credentials as the wireless router changes.
