@JoseMY. I just purchased an OTG (On The Go) cable and am interested in getting it to work on my Nexus 4 running Android 4.4. Any help would be deeply appreciated. I would like to send/receive text or data with an Arduino Uno if that is possible. I know the cable was initially designed primarily to run a printer and could probably find one to hook up if necessary. We might have to start a new thread if you’re interested in pursuing this.
