Sorry for my ignorance, but I'm new to AJ and I couldn't find a complete answer to this anywhere.
When an app advertises itself, where does the advertisement go? Is there some sort of a DNS for AJ apps? And where do apps search for providers? I'm clueless about the communication requirements of AJ - does it require an internet connection? Or only a hotspot?
There probably exist answers to this which I couldn't find, please feel free to refer me to existing pages.
Thanks in advance, Amit
