How to get started with M2 and SuperB?

So I’ve been playing with my M2 and Savvycan, using M2RET. That has been working great and I’ve done a lot of logging.

My goal now is to send data through the GMLAN (SWCAN) via my Android phone connected by bluetooth (serial?). I’ve read through the docs, tried various sketches but I’m at a loss of how to proceed.

Could anyone point me in the right direction? Thank you.
