Whats the otg cable for and is it a simple hook up thru bluetooth and go thing to get this going?
sent from my RAZR MAXX
The otg cable is a micro USB(male) to USB(female) cable. This allows you to connect USB devices to your Nexus 7 through the otg cable. You can connect flash drives, external hard drives, controllers, etc.
It doesn't hook up through Bluetooth. You just plug it in straight to your N7. It's way simple, even a kindergarten can do it, lol.
If you want to use a flash drive of some sort, you'll need stickmount(if you're rooted) or Nexus Media Importer(not rooted).
I currently use this otg cable along with my Buffalo Mini station 500gb external hard drive and it works like a charm. Still get powered even when the nexus 7 has 4% battery left.
