Wondering if this is possible. The main limitation is the file says, lets say on average 8mb. From what I can see so far, the XBEE type TX/RX won't work because of data rates. If I found the right numbers, it looks like using those type of methods would take 4 minutes to transfer. This leads me to believe that a WIFI protocol has to be used. So essentially what I need to do is:
usb data out of device, into the Arduino that is battery powered. TX through WIFI (something else?) to RX small arduino. The RX arduino just needs to the data and put it into a USB port on a laptop lets say. So both ends look/feel/act like a USB cable was plugged in, but in between it's wireless.
I essentially want to do what these will do http://www.amazon.com/Cables-To-Go-29570-Wireless/dp/B001JEPC3G/ref=pd_sim_sbs_pc_4
except not all the extra hubs, and the "dongle" attaching to the device needs to be self powered (not powered through the USB connection).
Any thoughts on how to do this? Where to start? I tried searching around and can't find any real information.
