I'm currently trying to build a robot based on the Arduino Mega. Now I wanted to expand my project by using an Arduino Mega ADK r3 + Samsung Galaxy S3 so I can use the S3's Wifi and sensor capabilities. Also I wanted to use the much faster processor and the mass storage inside the smartphone.
But trying this, I have encountered the problem, that my phone doesn't communicate with the ADK. The ADK's sample sketches to parse descriptors of usb devices works with mass-storages, mice or keyboards but my S3 seems not to be sending any data. It just uses the arduinos power to recharge.
Any ideas what I could be doing wrong?
