I'm interested in developing hardware which would communicate via wifi with an iPhone. I know this is typically accomplished over a home network or the like, but I was hoping I could stick a chip (I'm currently looking at a Microchip TCP/IP Stack with BSD socket) into the device that would negate the need for a router middleman. Basically, is there a way that I could create an ad hoc wifi connection between the iPhone and my device whilst avoiding the need to go the MFi route?
