Hello,
i'm trying to use a Due with a Nexus4 phone. I've compiled an loaded the sample successfully (thanks to your code modifications tips

, but when i plug the Due on the Phone, the phone battery charge status start to blink, and i get a repeated "disconnected" message in the arduino serial console. (the phone detect an adk accessory sometimes, somtimes not...)
I use a USB-A female <-> micro-B male on the phone side (not referenced as OTG), is it a problem ?
Another question, has anyone tested a blutooth shield on the Due ? and the ADK2-over-BT feature ?
Thanks.
Anthony.
