Hey,
The Hardware I'm using is an Arduino Pro mini (3.3v) and an RFM69HCW on the Adafruit breakout board.
The LPL sketch that works is below, as for the MySensors one It's basically just the examples (as a serial gateway and node) that won't work.
// Sample RFM69 sender/node sketch, with ACK and optional encryption, and Automatic Transmission Control
// Sends periodic messages of increasing length to gateway (id=1)
// It also looks for an onboard FLASH chip, if present
