I bought a couple of these on a discount deal today. My previous model ended up being an E02 and less of a struggle, but ran across this site for dealing with the Oxnas and thought I’d better bookmark it now. I’m thinking of using these devices either as a headless barcode scanner for grocery and inventory purposes, or possibly some tinkering for door/window sensors or an Internet relay for my garage door.
