Some, if not all, Fuji X-series cameras seem to contain a Wifi (802.11) network function with ability to send/upload/download files and possibly do some tethered shooting or remote control.
Mostly Fuji mentions this is for using their specific "apps".
There seems to be all the needed mechanisms for sending photos to a NAS or website or doing unlimited timelapses etc (whatever a dev dreams up) if only it could be automated instead of being stuck with interactive proprietary tools.
These could be killer documentation cameras (consistent manual exposure), for example.
Is there any better information or documentation on how this system works, what protocols might be involved, and whether there is a way to develop applications for this yourself?
