Hi all,

I've seen a few Android projects around using bluetooth bridges, but I was wondering if anyone had thought about connecting a 3DR radio to an IOIO board (IOIO board contains a single MCU that acts as a USB host and interprets commands from an Android app) for telemetry/control from an Android device?

They seem to both support UART, and my phone fits in my pocket, unlike my laptop!

I'm a Java/Android programmer, so I'm comfortable I can write a Android UI, and the IOIO SDK seems pretty straight forward, but I've never used UART etc before.

I also believe that there is no native java mavlink library, and JNI is the way to go, but I've never used JNI on Android (although the copter-gcs project seems to have done this!).

I've got a IOIO board to play around with already, but not 3DR radios yet.

Does this sound feasible?Could I test this simply by plugging into the APM2 telemetry ports and then just plug in the radios at a later date?
